Samsung TV makes a strange clicking sound
My Samsung TV (52″ LCD) started clicking several times before finally switching on after 30 seconds, this relay clicking gradually got worse each time I turned the set on. ( It turns out that this is quite a common problem with Samsung TV’s of all sizes). The problem seems to start after the TV is a year or two old (normally outside guarantee) and sounds like a relay clicking on and off. Samsung deny there is a design problem, so I thought rather than spend money on an engineer, I would try and fix the problem myself.
I thought the first place to look for a problem like this is in the power supply.
- I unscrewed the back cover of the TV (20 screws)
- Removed the metal cover of the power supply (4 screws)
- I carefully looked over the power supply looking for anything out of the ordinary, low and behold I could see a few capacitors (the cylindrical shaped components) that had raised tops. These raised tops are caused when the capacitor breaks down and forms hydrogen gas, if left, eventually the capacitors will blow, and hopefully the top will split open and release the gas pressure, if not, they may just explode.
Check out Capacitor Lab for more details on what to look for when a capacitor fails.
I checked out the replacement cost of a new power supply board, I couldn’t find the exact power supply online but this company has ones for smallers TV starting at around £160. So I was guessing it would be around £200 for a new one. Ouch, definately time to DIY.
I decided to replace all the capacitors in the power supply, I guessed if some were bad, then probably Samsung use cheap or poorly designed capacitors and at some point the others would go bad too. and replacing all the capacitors wouldn’t cost much more .
Each Capacitor has 3 important values
- The capacitance measured in μF (micro farads) eg (1000μF)
- Voltage (eg 50V)
- Temperature (eg 105°C)
This particular Power Supply Unit (PSU) has 3 different types.
- 1000μF 105°C at 10V
- 1000μF 105°C at 25V
- 47uF 105°C at 50V
RS Components have a good selection, so I opted to buy from there. It cost about £12 including postage for a 5 pack of each of the capacitors. I took a few photos of the circuit board so I wouldn’t forget what I was doing and set to work.
I re-opened the TV, and completely removed the Power Supply Circuit Board, you need to remove several connectors, again, I took some photos just in case I couldn’t work out where they all went when putting it back together. I made sure the Power Supply didnt have any residual power stored in the capacitors by unplugging the TV (whilst it was turned on) from the plug. This is very important as messing with a power supply even 30 minutes after it has been turned off can still give you a nasty shock.
I then drew a simple diagram marking the polarity of each capacitor. To remove each capacitor takes a little time, you need to heat each pin using a soldering iron and whilst it is still molten pull or wiggle each leg out in turn. I found it easiest when I used the other leg as a pivot and rotate the capacitor around the fixed leg.
Anyway once removed, you I used the de-solder pump to clean up any solder that was clogging up the hole and then I inserted a new capacitor (checking the values again) and making sure the polarity was same as the one I had just removed. turning the board over, I bent the pins a little, soldered the joints, and snipped off any left over wire.
I put the board back in and hey-presto it all worked beautifully. Job took about 2 hours in total and excluding tools £12 for the components and postage.

If you snap off the solder connector on the PCB when doing this replacement, it is worth noting that you can re-attach your component in another place as long as it is electrically equal. The Red Line in the diagram below shows where an existing component was, this component could then be re-soldered into any of the positions marked in green. But in the case of a capacitor which has + positive and – negative legs, you must make sure that the leg is re-attached to the same track, I have marked with a + plus sign which track it must be re-attached too.
[Added 7th Dec 2009]]
After replacing the capacitors a few people are still having problems, it appears that this can be fixed by resetting the EPROM chip (apparently – a simple matter of shorting two of the pins). http://www.tv.quuq.org/forum/index.php?topic=2377
and http://www.tv.quuq.org/forum/index.php?topic=1744.0 both detail the procedure, although it hasn’t worked for everyone who tried it. (Thanks to Jason for these links)

You are not alone, there have been almost 65,000 visits to this page in the last year. The answers to many of the questions people are asking are scattered through the previous comments, Most people with little experience have been successful in fixing their TV’s although for a few, it didn’t work, the symptoms were similar but cause was different. A few of the more recent comments reveal that people are becoming more successful with getting Samsung to repair their TV’s, its definitely worth trying before you launch into a self fix.

I have a NEC monitor and I like it, no problems, and it even has speakers on the monitor that are loud. Not to mention they have good prices, as far as samsung goes Ive had a samsung air conditioner that broke 2 weeks after buying!!!! This was last summer and there customer tech still hasnt come to fix it for me!!! I used to think samsung was a good company because of their tvs have excelent picture quality, but In the past year I have discovered that they are whack! They use cheap parts and sell their products at top of the line prices, I think ima look into buying sony, or phillips because Ive had some phillips electronics since I was a teenager and they are STILL in great working condition, so maybe my next tv will be a phillips. Oh yah for any music people out there dony buy Numark either there shyt sucks to, so does there customer support
I have a Samsung LCD LN-T4669F with power up problems and brought it from Plasma Bay.com and the extended warranty from servicetech.com both out of business feel so ripped off and extremely disappointed in Samsung especially after all the good press there products are getting.
Do not,I repeat do not ever buy a Samsung television they should not even be selling tvs. I bought a Samsung television in March of 2008 and about a year and a half later the power is out of it. I have another brand television that is still going after 12 years. If I can save many from this disaster I am content.
Hi,
Well last night the TV which has been running 24/7 as I knew it wouldnt come back on went off with a blip in the power supply. I had always intended trying to fix it over the Christmas holiday but this made it a must do and also the capacitors which I had ordered from Maplin arrived today. My son dismantled the TV and got the power supply board out. There were 2 capacitors with raised tops and thankfully the spares I had ordered were compatable.About 30 mins later the new ones were soldered in and the TV reassembled.
Switch on and BINGO TV now works as new.
Its a shame Sansung are acting this way as I still think the picture quality is one of the best in its class, even more annoying is that we have 2 other Samsungs which are older and have never been a problem.
Thanks again for this web link as I just could not afford what the TV repair companies want for this simple repair.
I am also annoyed that none of the so called consumer investigation teams were interested in showing up what seems to be a major problem, what do you have to do to get them interested?
Anyway Merry Christmas to everyone and this repair really is worth attempting
BILL
SAMSUNG TVS ARE JUNK!! They start clicking and burn out just after the warranty expires (ALL MODELS}. There are thousands of screwed and pissed off Samsung customers that were told by samsung TOUGH LUCK SUCKERS!!
I came across this post cause my samsung plasma started doing the exact same thing. however I opened up the back of the set and inspected the boards inside, none of the caps show signs of swelling or any other type of deformity. Mine will click every few seconds and if look down from the top of the set I can see a set of 3 green LED’s. The two outside ones are lit and the 3 comes on and flashes for a second or two and the relay clicks it off. Sometimes it will sound and turn on for a second, I even saw the “Component 1″ source id in the corner but then it died again.
Any other ideas as to what to look for?
I been having have this same clicking noise from my LN-T4665F its just 2 years old. Not sure if i should call for a repair quote. I have been putting the TV in PC mode and letting it go to sleep instead of shutting it off. I just use the source button when starting it up with no clicking noise. Not sure how long this will last but seems to be working for now.
MatthewB: that’s a clever colution, I hadn’t thought of that! However, I do know that even if you leave your TV on constantly, it will eventually cut out (and you may do further damage) – because that’s what happened to me! Another thing which might prolong your TVs life is to switch it to one of the “energy saving” modes – they seem to decrease the brightness of the screen, which presumably means it uses less electricity
i have a 42″” samsung l.c.d t.v,i already checked the capacitors and they are obselete,{leaking considerable amounts of black gunk}….trouble is my old pals,i dont know how too order the blumming things from r.s,can anyone supply me with the correct codes……many thanks……….leigh,leicester,england……….p.s happy new year…
Just want to thank you guys for all the help because I was able to successfully repair my bad capacitors. It actually was quite easy just need a steady hand and good eyes or magnifying glass…lol MY LN T4669F samsung is back up and working just fine and no more clicking
Wow! I feel better and had to write (I never do online) back to all of the people and Chris. I have the same problem with the clicking TV. I own a 52″ inch Sam..ops meant Shitsung and after reading and knowing the frustration that you all feel and the betrayal on loyal customers (and want to prove wife wrong that I can repair it)haha. I also thought Shitsung was reliable, but I did not research long enough and made a bad decision I hope the company AND SAM (rich shit head) come out and do something to save face. Needless to say I will not purchase another Shitsung product any time soon and I will spread the word. I will keep you all posted.. HAPPY NEW YEAR to all you good people, amazing how well we do when we work together.
Hi Chris,
Just done my repair. Followed your instructions. My TV is the LE52M87. Cost me £19.99 all in for the soldering iron, capacitors, solder, desolder wire (which is lame, get the solder sucker) and a solder iron holder. All from Maplin. Took about 1hr. All working 100%!! I couldnt be any happier!
Thanks Chris for this article ill sort ya out a cup of coffee as its saved my pocket and the Earth.
many thanks and merry new year sir,
frank.
Been having the same problems mentioned here, and right around the 2 year mark as well…go figure… I bought a 3 year extended warranty so I beleive im covered, but me thinks this is DIY job as I dont want it replaced with the same crap.
Looks like I wont be a return customer to Samsung…I have a 32″ LG flatscreen that I like better than my 52″ Samsung…I think my next flat will be an LG
52 inch LCD Samsung. We had the capacitors changed yesterday and the TV was working great all evening. Woke up this morning, turned it on and nothing but sound and a black screen with a thin line of color on top and one in the middle. Any Ideas??? This TV is two years old.
Make sure the caps were installed correctly if you put them in backwards they will blow out. Electrolytic caps are sensitive to polarity and the board is marked and you can see a neg sign on the cap. If that’s not it I suggest you take it to a tv repair place.
I have a 42″ that I just replaced the 4 1000mf caps on and it works perfectly now. Thank you so much for the info.
Also, if it helps for anyone that has an old Motherboard from a computer, you can usually find the 1000mf capacitors on there and they are generally about the same size. I pulled mine from an Asus K8V Mobo, they were 1000mf 16V 105C, perfect fit. It will save a little time and money if you already have something like this lying around.
I think we Please report these issues to FTC.
http://www.ftc.gov/
sorry…pressed submit too fast..:) I was trying to say is that we should all submit a complaint at ftc.gov.
Same problem with my Samsung 40″ LNT4061FX/XAA, Version CN06. Opened it up today to check it out and found there are 3 different capacitor values in the “problem area” and no cage over the power board. (2) 1000uF 105c 25V, (2) 2200uF 105c 10v, and (1) 1000uF, 105c 10v. The (2) 2200uF 10v are obviously shot. The (1) 1000uF 10v shows no signs of damage but I will replace that as well. Should I go ahead and replace the 1000uF, 25v caps too while I’m in there? I only ask this because several blogs seem to indicate the cause is the 10v rating. I have no problems replacing those as well just looking for a thoughts from those with expertise in this.
I finally open my LN-T4665 and found 2 of the 2200uF looking opened up. All the others seem fine. I have not replaced them waiting for parts to arrive. I was just wondering if I should change all or just the damaged ones.
There are only 2 10v caps in my power supply all the rest are 1000uF 25V.
I have some great pictures but not sure how to upload them.
Thanks
Hi Matthewb,
For some reason the 46″ power supply seems to be a bit different to the others.
I found exactly the same it was the 2 2200uF that had very slightly raised tops and some black staining on them. I replaced theese 2 and the TV now works like new. As someone pointed out before it is a 12volt power supply and it seems to be the 10 volt capacitors that are pushed over the edge.
Hope this helps
Bill
PS the 16 volt replacements that I got are slightly bigger in diamater but you can still fit them ok.
Thanks William (UK) I did order 16 volt replacements. Did you just leave the all the others or did you replace them?
Thank God for this page. My Samsung LN-T4053H started getting that clicking noise before tuning on a while back. At first it was only a short time of clicking and it was bearable, but later the time increased to over 30 minutes and then it wouldn’t turn on no matter how long I tried.
Then I ran into this page and found the solution. Many thanks. I read all the comments and was a bit worried I permanently damaged the tv for leaving it on with that clicking defect for so long. Luckily it all turned out fine.
I would recommend you buy soldering braid (sold at radioshack for $4) to take off all the solder before pulling out the the capacitors. Just put the braid on top of the solder and place the iron on top of the braid. Keep it on top for a few seconds and the braid will suck up the molten solder. Takes a few tries. After taking off the solder, use small pliers to bend the wires straight and the capacitor will fall right off with a small push. Resoldering the new capacitors was fairly easy in comparison to taking out the old ones. I found that using the smallest tip available on the iron made it easier to put on just the right amount of solder. Search for some videos on youtube for proper soldering technique before attempting all of this though.
Only the the four 10v capacitors were bulging, but I replaced all seven capacitors with capacitors of a higher wattage just in case. Here’s a pic how it looked before the replacements.

Here are the exact capacitors I bought for those of you interested.

Two 1000uf 35v 105c to replace the 1000uf 25v capacitors.

Note: The two original 1000uf 25v capacitors were different sizes (one was bigger) but had the same specs. I don’t think it really matters if you replace the capacitors with ones of same physical size. Turned out fine for me.
I also had an old broken HP LCD monitor that I fixed right beforehand for practice. It had the same capacitor problem as the tv.

I have a 52″ Samsung LCD (LN-T5271F) that is exactly 2 yrs and 1 month old. Two weeks ago it started this exact clicking behavior which lasts about 30 to 40 seconds before it comes on. I would like to try the repair myself as I see many are having success at it. However, I would like to find out which capacitors I need before I start taking it apart. Is there any way of doing this. Also would like to know which screws in the back to remove if all of them should not be removed.
Thanks
HI Matthewb
I only replaced the two 2200uf x 10volts that had raised tops, everything else was ok. Replacing the damaged two capacitors with 2200uf x 16volts worked like a dream, TV now perfect.
Bill
Hey thanks very much for the info Bill.
Cheers from Canada
Look for the ones with the tops pushed up on my TV it was the 1000UF 10v caps like in the pictures above. I have a Cap tester and I pulled all the others and they all tested good. Replace them with 16v caps that should do it make sure you put them back in the same way they came out. They have a – sign on one side the board is marked.
DanH – You really can’t tell which are bad before going in. Taking the back off should be a breeze though. You will take off all the screws with an arrow pointing at them, and probably the base (if you installed a base rather than wall mount). You can take the back off, look at the capacitors to see which to replace all within 10 minutes.
DO NOT BUY A SAMSUNG TV. I HAVE MODEL LNT4061FX/XAA AND WE HAVE HAD PROBLEMS WITH IT FOR A YEAR. NOW THE TV WILL CLICK FOREVER AND NOT TURN ON OR IT TURNS ON WITH RAIBOW VERTICAL LINES UP AND DOWN IT. IF YOU KEEP IT ON FOR A FEW MINUTES LIKE THAT IT WILL SHUT OFF AUTOMATICALLY. THIS SAMSUNG TV IS A PIECE OF SH*T!!! NEVER AGAIN WILL I BUY ANY SAMSUNG PRODUCT.
Wanted to thank everyone involved in these post and the how too repair and replace the 2 caps. (2200uF 10 Volt in my LNT4665F) I replaced them today and the TV works fine. Only took about 1 hour by the time I removed it from the stand and save at least 60 to 120 dollars. The caps cost 1 dollar each and 4 dollars shipping. (Canadian dollars)
Thanks to all involved.
Screw you Samsung you fooled me once it wont happen again!
Thanks to EarthInfo.org and all you contributors. With the help of your comments I fixed my 2 yr old Samsung LCD LN-T5271F. The problem was the progessively worsening clicking on and off before the TV would turn on. I found 2 bad 2200 microfarad capacitors when I removed the power supply circuit board. I had seven caps all together so I just replaced them all with higher voltage USA made ones, just to be safe. On Sunday it took a few hours to take it appart, determine what size caps I needed, and then order them online. On Monday I bout the few tools I needed. On Tues morning at 11:00 am FedEx handed me the new caps I ordered. By 5 pm I was turning the TV back on to discover problem fixed.
The caps I found and the ones they were replaced with are as follows:
Cap #851, #881, #854; 47uF/50v/105 C replaced with 47uF/63v/105 C (PN:476CKE063M)
Cap #853, #852; 2200uF/10V/105 C replaced with 2200uF/25V/105 C (PN:228KXM025M)
Cap #876, #880; 1000uF/25V/105 C replaced with 1000uF/35V/105 C (PN:108KXM035M)
Cap #850; 1000uF/10V/105 C replaced with 1000uF/25V/105 C (PN:108CKE025M)
I purchased the caps on-line from http://www.alliedelec.com.

Hope my info helps someone else.
This guide worked perfectly for me!
The story:
I bought my TV online from PixMania two years ago, which after I ordered came out to be in France (I live in Norway).
It started clicking before power-up a few months ago and gradually got worse until it couldn’t turn on at all.
PixMania required me to send it from Norway to France, bearing all costs for shipping myself, with no warranty that they would fix it for free. Samsung Norway wouldn’t even hear of this as this model was not imported to Norway.
Paying a workshop to fix it locally would be really expensive.
Started googling the problem and stumbeled over this guide!
Screw Samsung…and PixMania.
Thank you to the Author.
I have a Samsung 42″ LCD TV. It starting making THAT clicking sound and rainbow image everyone else describes.. when you google SAMSUNG CLICKING. My friend came to fix it and immedietely said it will be the capacitator’s. We did a search on You tube and there you have an excellent video showing you how to fix the problem easily!!!! Samsung should be reported to the Office of Fair Trading! It is a manufacturing ploy as it happens after around 1 year. I also checked out the many complaints on Google. Also, if it has just started happening to your TV, it seems turning off the supply from the main affects it more. My friend has now gone home to get the capacitator’s and hopefully I will be watching the TV later this evening! Will keep you posted.
Should I have any concerns over the capacitors I’m removing needing to be discharged before I begin to remove them? I intend to do the work shortly after powering off the TV. If so, how should I discharge them?
Hi Katrina,
I contacted Samsung when this happened to my TV. They told me to unplug the set from the mains for a minimum of 8 hours and then retry. Then they curtly stated that if this did not fix the problem, I would require a non warranty repair, end of story as far as they were concerned!!
Bill
Hi all.
I too have had the dreaded clicking issue. (Bought from Tv’s Direct).
Tv has now finally died! Model is LE40R74BD with PSU BN44-00134A. Have identified the blown caps as:
CM806,811,812,817
811 & 806 are both 1000uf / 10v but i can’t see what the other 2 are are they have been fixed facing away so i’m assuming they are the same – Can anyone confirm this?
I have sourced a great place with free delivery (UK) called Farnell (http://uk.farnell.com/) although I think they have international versions.
I have decided on replacing the 10v with 25v.
Here is the part:
http://uk.farnell.com/jsp/search/productdetail.jsp?sku=1219471
It looks like this is ok but there a lot of specs here and I just wanted confirmation that this is ok before I order.
Thanks for all your help folks.
To Will: To discharge capacitors I read you need to wait a few hours at least after unplugging set from the wall. I also read in order to discharge faster and more completely, unplug set from wall while it is on. What I did just to be sure, the night before I unplugged set from wall while on and the next morning I worked on it. This way I was sure no juice was still stored. Wanted to be as safe as possible. From what I read it sounded like you would be safe after a few hours so whatever you decide. Hope this helps and good luck.
Actually this post me in more in trouble.
I called a technician to replace them, and they estimated $70, and I tried to look on the internet and come accross to this post.
I decided to do it by myself. I purchased all the mentioned parts for $45.00 + tax and while doing unsoldering, I ended up in damaging other component, also had to replace the whole power supply. I ordered a power supply and again re-opened the TV but because of my bad luck, I dropped the TV and damaged it completely.
I would strongly recommend to those who really are aware of what they are doing.
With my experience $70 was worth spent.
We replaced the three ‘damaged’ capacitors amd still not working CLICK CLICK CLICK. Friend gone back to get brand new set for ALL capacitator’s. Not sure what will happen next in the ‘clicking’ saga.. we shall wait and see!
@Will (and others) – I unplugged my television from the wall with the power still on. It was only about an hour after I unplugged it (I took the back off, arranged my workspace, desoldered the capacitors I wanted from my old motherboard) before I went in and started unplugging the cables from the power supply board and started desoldering the television capacitors. I ran into no problems with a stored charge, but it never hurts to be safe.
@Rico – You are right, if you are unsteady or have never soldered before this could end up being a more expensive repair than if you had someone fix it. I would recommend practicing on another circuit board (who doesn’t have something that doesn’t work lying around they can take apart to practice on right?) If you practice on something, make sure you are able to remove parts cleanly, take your time, are removing all solder with a desoldering pen and/or desoldering wick completely (so you aren’t unintentionally bridging trace lines) and are not burning the board itself from too much heat from your soldering iron. A little practice goes a long way, I would much rather spend an hour getting used to soldering and desoldering on something I can throw away than jump right in on a mulit-hundred or more piece of equipment I don’t want to make worse.
@Stu – The capacitors will be fine as long as the heat rating is the same (should be 105C) the capacitance value is the same (uf rating) and then you should also be aware of size. It seems most of the 16V capacitors are the same or close to the same size, whereas a lot of the 25v caps seem to jump up in size. There is room in the box for them, but on the board itself you have to worry about the caps touching or being to close together because they are larger. Something to consider anyway.
I want to say thank you to whom started this website! Cheers!
I own a Samsung LN-T4671F and that clicking sound started about 18 months after ownership, I dealt with it for about 2 months until yesterday it would not start after 3 hours of waiting. So it was time for this fix! I went to a local electronics store in the suburbs of Detroit Michigan, and bought (2) 2200uf 25v 105c and (1) 1000uf 25v 105c capacitors, when I went to pay for them the clerk was about to ask what I was working on, when he saw what capacitors I was buying, he said “don’t tell me a Samsung LCD TV”? I guess someone prior to me bought the same capacitors and was fixing his TV? Yes because of this site, he was doing the same thing! He even had printed out every page to have a step by step guide?
I am going to write something I hope will help some people how to fix this, somethings that others have not wrote!
I am a Design Engineer, and have a little electronic experience, enough to be dangerous! LOL
1) drain the electricity from the TV, by either unplugging it for a few hours or by pulling the plug from the wall while the TV is on!
I had help with adding the new capacitors, I held the board and the tool while my friend lined up the capacitor, once in position
just like a laptop, you remove the battery or plug, then hold down the power button.
2) remove all screws from the back of the TV, they will be marked with arrows next to the holes. If you are using the stand
(not mounted to the wall) it too has to come off! I placed my TV on my bed(something soft) so the screen will not get damaged.
3) remove the metal shield covering the circuit board held on by 7 screws.
4) some wire connectors need to be removed first, before the cover, do not worry all wires are connected by idiot proof connectors
in other words they can only be connected one way! Do not force them on! and on my TV the only 2 connectors that are the same are
the blue and white wires at the bottom, the wires coming from the left go to the left connector and the wires coming from the right
go to the right connector!
5) remove the circuit board by removing the 6 screws.
6) Now comes the fun part, SOLDERING, you do not need to be an expert at this! Just a good soldering tool is needed, a high watt is
preferable. On the circuit board should be a number of the capacitor you are replacing (for me it was CM850, CM852, and CM853.)
I noticed on pictures of other repairs here, that each TV is different on placement of the capacitors. To remove the old capacitors
hold the capacitor you want to remove (pulling lightly) and apply the soldering gun to wire on the other side, the board has the
numbers and a circle representing the capacitor you are removing! Do not worry about the old solder in the hole. Remove all old
Capacitors.
7) on the circuit board is a circle, half the circle is what we call “Cross hatching” (lines on an angle) this represents the negative
side of the capacitor, you want to line the negative side of the capacitor to this, hopefully the capacitor is marked with a minus
symbol or a silver stripe?
I applied heat to the old solder as my friend pushed it through. When the capacitor was seated I applied more solder and made sure
it was secure after cooling. When all three were replaced I cut the excess wire off the capacitors.
9) Re-install the board and wires, the cover and screws! Plug it back in and hopefully enjoy a tv that starts immediately!
That is it, not hard work and can be done by anybody! You do not need a de-soldering tool to do this, I had one and never used it!
I should have taken pictures of the work I did, you could not tell it was touched or replaced, no burning of the board or excess
solder, it looked professional! You do not need to add a lot of solder, and pre-tin your tip of the tool, doing this you need a wet sponge, add a little solder to it and wipe it on the wet sponge!
I do not believe you need to replace all capacitors like some has done, only the 10volt ones! 12 volts going through a 10 volt
capacitor is not a good practice that any reputable electronic company should be doing!! And Samsung has lost a customer that will not
be back to buy any of their products!
This cost me about $15.00 for the whole job, I am lucky my friend had the soldering tools, even he was afraid to do this!!
I was not, look at it this way, you would have to replace the board! But it will probably have the same crappy under volt capacitors
on it, and you will have to replace it in a year anyhow? So give this a chance!
Hope this helps!
Hi All
As you will see by my earlier posts, I was starting to despair.. however, I had some faith by what I had been reading on the Internet about ‘CLICKING SAMSUNGS’… and knowing someone who could fix the problem. Well I can proudly announce that my TV is now fixed!!!!! Yes, after my friend buying new capacitors and still not working, we read up more and found out it may be the eeprom needs re-setting (I had never heard about these things before) but I have learned a lot through this experience.
As mine was connected to Sky TV it had no problem retuning.
It is like magic when the set comes back to life!
Paid my friend enough to buy a few pints!!
I suggest us ALL complaining in review sites anywhere selling SAMSUNG TV’s!!
I pasted below for those who still have problems after putting in capacitors:- This was the magic trick. These instructions are almost EXACT and needs to be followed in that order!
This is for model: Samsung LE40R88BU
On this model the eeprom in question is IC 1803 (24C256) 8 pin smd and is located on the underside of the main board near the common interface. The clock and data pins are pins 5 and 6 and are identifiable by the 100 ohm smd resistors connected to each of them. Fit a shorting link (on long wires) between the pins. Reassemble the chassis. Switch on and then remove the short. Bring the set out of standby. Now access the service mode as follows-
NOTE ON HOW TO RE SET EEPROM
Using the remote control, switch to standby, press info, menu, mute and power. The set should start and display the service menu. Using scroll keys select item 8 and enter by scrolling right. Select “tuner” and set to auto. Revert to previous screen by pressing menu. Now scroll to “reset” and enter by scrolling right. The set will revert to standby. Power back on and tune in stations. Thanks again tv john for the information.
Hi,just wanted to say a big thankyou to this site for helping me repair our tv, just like everyone on here our 52inch lcd started clicking ,eventually refusing to come on at all ,its less than 2 years old and was pretty expensive too ! Samsung should be ashamed of themselves, I repaired my tv at a cost of £2-60, local tv repairman would nt even look at it, so what the hell have a go ,tv not working anyway so what to lose ? It was so easy even for me a woman !!!! Thanks again to the early pioneer who was brave enough to tackle the problem and share with us ,YOUR A STAR !!!
Just wanted to say thank you for this guide. Saved me a lot of time and money. TV has been fixed and working like new!
Happy new year!
I have a Samsung LE46a796, with some clicking noise in between, even when in standby. I dont know if this is the exact same problem as the others here. The tv is working perfect, just a little annoying with this small clicks. This tv i bought in may 2008.
Thank You. This was the second time for this problem. First time was $475.00(transport and repair shop). THIS time I did the repair…Parts : $1.76, one hour of my time, points to self esteem priceless
Annoyance at the bad design: ENDLESS.
I sent this to samsug and here is what they replyed.
My 2 year old TV
NOT HAPPY
I did a lot of research before purchasing this TV. It was very expensive purchase. I have been very pleased with the picture quality but when it started clicking on power up a few weeks ago I got nervous. It started taking longer and longer to start up. (more clicking each time) I of course call the service center and I was told that the TV is out of warranty and was given a phone number for a repair shop.
I did a little search on the internet and found a surprising amount of answers and how to repair.
I cannot believe that 2 pieces a dollar each was the fix to the clicking and start up fix on the power supply. I have replaced these capacitors (2200uF 10 Volt) myself and the TV is working fine now. I’m sure that this is not the first time for this complaint.
I bet that this small problem is costing Samsung a lot of money in sales because a lot of people are talking about it.
Here is some good reading http://www.earthinfo.org/samsung-tv-makes-a-strange-clicking-sound/
Thank you for submitting your inquiry to Samsung.
You are correct Jody.
But technicians in North America do not work at the component level, they would just relace the parts.
capacitors burn out due to power fluctuation, its all depends on how much fluctuation are there on the line.
Thank you for the info. I have submitted to our quality control department.
They wont get anymore of my money
i have a 42 inch samsung lcd,can anyone supply me with the correct codes for the capacitors on the psu,would 52inch capacitors work for a 42inch model,please desperateee.thanx leigh……………happy new year everyone.2010

Best bet is to take it apart and have a look so that you get the rigth ones the correct amount. You will also get to see what ones are burnt.
