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.

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.
[Added 28th June 2010]
Before attempting repairs yourself it is probably worth trying to see if Samsung will repair the TV for you, Samsung seem to now accept (unofficially at least ) that there is a defect in these capacitors, and in an increasing number of cases will send out an engineer to fix them. Skim through the comments below to get more info.. A polite but assertive approach seems to yield best results, remember they are in the wrong and there is plenty of consumer law in most countries covering their liabilites and responsibilities.
If you fail to get Samsung to repair it, 100’s of people have had success with the replacement fix I describe above, a few of the failures are probably due to similar symptoms but a different fault. Again if you are unsure read some of the 100’s of comments below

THE P, the 4671F is the same exact one i have, can you please tell me the capacitors you used for the fix? worried that a higer voltage one wont fit, the current one is 10mm a 16v replacement is 12mm there are two and both very close, almoast touching
Great news! I had the same problem stated on this message board but I could not see any defective capacitors. I decided to replace the 6 largest capacitors in the power area and it worked. I can’t thank you enough.
I’m so happy! I reported 2 days ago that my 4061F was sound only. I bolded went were I had no business going, but Chris made it sound so easy. I found my two 2200MF 10V 105C with popped tops. I replaced them with 45volt and it all just seems like a bad dream now. THANKS!!
Hi, i have a problem with my 32″ LCDTV. When i go to turn it on, the tv turns on but after 1-2 secs, there is no picture, but still sound. is this the same problem and how do i go about fixing this. i’m in the army now doing training and i dun have alot of time to research the problem.thanks
well done lee smith for getting your repair. but i can top that now
i have same tv as you. when samsung paid for repair the retailer put on another fault doh. they then sent tv to samsung,
samsung dont make tha required circuit board anymore, guess whose been offered a BRAND NEW 5 series 1080P replacement by samsung.
what a result for my efforts.it comes with another 1 year warranty.
im now happy with samsung again.
minor point:- you do not have to get an engineers report. (its the retailers stock fob off comment to scare you off.) you only have to prove its an inherent fault.
telling them you are confident enough of your facts to sue them (the retailer)for the FULL cost of the tv as compensation is usualy enogh to convince them to pay for your repair. being assertive but not aggressive is the key to success.
I’ve had this same problem over the past few weeks, on an LNT-4669 I bought 1 year and 7 months ago. It was getting so bad that I was afraid to turn off the TV. So after finding a few posts about this manufacturer’s defect online, I called Samsung customer service and politely asked them to extend my warranty to cover the fix. They did, and the repair is scheduled for this week. Hope other non-techies like myself find this helpful.
Had the same issue with My Samsung that was 3 years old, 4 capacitors were swollen and buggered, have replaced at a cost of £2.58 from Maplin for new ones, Also bought the solder Iron there for £7.99 Bargin… Tv now turns on as new!!!! Thanks a million you have saved me a packet!
My TV developed the same problem it is 46inch Samsung, I had already diagnosed the problem I had had the back off and found the bulging Capacitors (different layout to the above), I had my son reading them and then put an order into Farnells. Then I found this post which confirmed what I thought good to see someone else has already done this.
Going to wait to the weekend till doing the fix, as must admit it is a little scary. But look at it this way if you don’t try then it is going to cost you at least £100+, even if it does not work you should not be any worse position.
Capacitors I will be replacing are :
2 x 1000uf 25v
2 x 2200uf 10v
I will confirm once I have got them out
There were some smaller capacitors but they look ok, so might replace depends how my soldering goes.
I actually use a paste to solder, had this over 10 years really easy don’t know if you can still buy. To use it you just apply to the joint and touch with the soldering iron instant perfect solder joint.
I have fixed 3 sky + boxes which had a simliar problems also replaced broken capacitors in two of my Homeplug devices.
So I am quietly feeling confident, will post when I have done the deed.
HELLO,,
WORKING ON A PC LAPTOP MONITOR ,WHITH THE SAME SENARIO
AND THERE’S A WHOLE SLEW OF CAP’S ON THE POWER SUPPLY, SO I USED A VOLT METER TO TEST EACH CAP, I HAD NOTHING ON 1 WHICH WAS A
JACKSON 470uf 16V 105C
SO I UNSOLDERED AND NOW NEED TO WAIT FOR A REPLACEMENT,,
QUESTION,::
DID I DO RIGHT BY USING A VOLT METER ON THE CAPS TO FIGURE WHICH ON WAS BAD, B/C THEY ALL LOOK OK TO ME,,,
THX
THE P
My replacement caps came yesterday. I needed 4 but bought 8 considering they were only $0.44/each. My buddy and I spent about 40 minutes pulling out the old and putting in the new. Put the TV back together and turned on like new. THANKS SO MUCH FOR THE HELP!!! Doesn’t change the fact that I’m still pissed off at Samsung for not assuming any responsibility for their crappy parts. Absolutely ridiculous! Go figure, all the capacitors that were over 16v were still completely fine.
Help, got the exact same problem with our 40″ Samsung tv, we’ve already changed the capacitors which did not solve the problem. Next we ordered a brand new ip board and swapped this over but the problem still exists. Does anyone know what to try next? Any help would be great, thanks.
my final post on this subject.
huge thanks to the 1st poster on this forum,showing the inherent fault on samsung tv’s
rather than self repair i chose the sale of goods act route to sort my 2and half year old tv. i was rewarded yesterday when i took delivery of the brand new 5 series 40”1080p tv from samsung.
it replaced my blown 40le73bdx 1080I tv that had the caps fault.
there was no charge for the replacement tv, and free delivery AND another 1year warranty.
thank you samsung for sorting my problem to my satisfaction.
good luck to the rest of you.
Ok all, did the repair earlier, took me about hour and a half. Most of the time undoing the screws on the TV, anyway everything back to normal, TV is working perfectly.
Ironically the capacitors I used to replace are Panasonic, so now my tv is a samsonic! or maybe a pansung! lol
On close inspection of the caps both the 2200uf 10v had blown. The others I am not sure about, I did end up replacing 5 capacitors as I thought I might as well do them all I had the parts.
2 x 1000uf 25v
2 x 2200uf 10v
1 x 1000uf 10v
Now got a perfect working TV.
For all those people afraid of soldering don’t be it is actually quite easy and it is not technical as people believe.
My thirteen year old son soldered the last two, and he had never done anything like it before.
Guys,
Why are you all fixing these yourselves… Samsung is responsible for the faulty good and the more people get on to the retailers/Samsung and trading standards the more that Samsung will realise that there is a serious problem and put a programme together to admit a fault and fix peoples faultly goods.. Appreciate it take a bit of tenaciousness but let us not let these big corporations get away with providing shoody goods !!!.. Good Luck..
To AKL,
I understand your comments and agree Samsung should be responsible. But if you go back and read some of these posts you will find many have tried and failed with Samsung. They also told me I had to have fixed and since out of warranty I was on my own. So how long do you wait and go without your tv while you wait for Samsung to get their act together?? If you can resolve yourself for under $20.00 I say why not. This web site and posts is the place for documenting all this and it will affect Samsung in some way. How many people have been turned off from their products now that they can read how they handle their business. I know I would now think twice in buying their crap again! My choice at the time was between them and Pioneer. Next time I will consider another brand much more highly. This is how you act against the big corporations, by pulling together here as a group. I think we have done a fantastic job of acting against that big corp.!!! We have also acted against another scam out there, the repair people who rip us off charging the big bucks to fix these simple things. I mean, $150 just to come out to tell you it needs to be fixed is crazy. You are at their mercy and they can tell you and charge you anything. So two birds have been killed here. Thanks for you comments…
Hi, my question is a bit out of context here but i hope anyone got an answer. I got a Samsung LN40A650 bought in usa , now i moved to Spain and got the TV with me, it’s connected to a step down power convertor cause TV says it’s 120v and current here is 220v. I was wondering if the internal PSU of this TV got a switch or something like that so i dont have to use the stepdown convertor. Just ask cause like the case of my PS3 says it’s 120v but it actually got a PSU that works with 220. Any help will be appreciated thanks.
I really need help I got fraud because someone on craigslist sold me a broken HPT4264 42″ plasma for 500$… I am broke and does not want to spend the money for repair. I am planning to fix the clicking sound myself. I have hoping that someone in this forum can keep in touch with me closely to help me repair my tv. I am going to take some pictures of my power supply later this weekend. Please email me if you guys can spare your precious time to help me repair my TV. my email is alan_ma123@hotmail.com
I replaced all of my capcitors, but I did not mark the polarity of each capacitor before removing and replacing. Once I plugged the televison on, it powered up but after approximately 60 seconds I heard hissing and then saw smoke. At that point I realized I didn’t check the polarity placement of each capcitor. Since the originals have been removed, how can I determine whether each capacitor is attached correctly?
@Trevor
Is it marked on the printed circuit board?
Take a look on both sides. If not, I think you should post the model of the TV and PSU (if their is a model # on it) and hope someone else who has the same model can take a photo or theirs.
There will no doubt be a way to do it by analysing the PCB (and/or using a multimeter to measure the voltage across the capacitors) but this is outside my expertise. Alternatively you may be able to get hold of a cicuit diagram which would indicate the polairty, however I have no idea from where. Sorry I can’t be any more help.
My 46″ Samsung LCD TV was doing the same thing. I replaced two capacitors this evening and the TV is working great! Thanks so much for this thread! Cost me a total of $10. Would have cost $400-$500 for the repair guy to fix it.
hi, i turned on the pc this morning to try and find the problem with my tv i could hear a strange clicking sound which sounded like a connector problem i tried many different repair places and all the quotes were very high i didnt want to pay this much anywhere between 100 and 400 i found your site and followed the instructions the parts that needed repairing cost me 2 pounds and the rest was a little concentration thank you so much at last i have a tv thats actually works again for a fraction of the prices quoted.
Did you replace the two with the blue rubber housing?
I cannot tell if they’re defective.
Thanks!
Same problem read your post found two that where bad and replaced YOU R THE MAN i dont have pay pal but would love to send u a gallon of coffee THANK YOU ITS PEPS LIKE YOU THAT MAKE THE WORLD GO AROUND
@Sage – as you already have the back of the TV and it costs so little to replace them (just a bit of time) – I would change all the capacitors
I have the same problem (clicking for a minute or two before turning on), and I have been in touch with Samsung. Because I’m out of warranty, they cannot help me, was the first line. I spoke with a nice rep who extended my warranty for parts only, and then sent me to a rather expensive tv repair shop, who won’t even look at the tv without me spending $96 (though that amount would be applied to the repair). I’m pretty angry about all of this, especially as this isn’t the first forum where I’ve seen so many complaints about the same problem.
I don’t know anything about capacitors or how to repair them, and yes, soldering is something that intimidates me greatly. I’d prefer to have an “expert” do the repairs. But, one option I was considering was taking out the power board or whatever it’s called and taking it to an electronics repair place to have them replace the capacitors. Even that scares me – fiddling around with the innerds of my tv. I just don’t know the best way to approach this.
I wish I were as lucky as the folks on here who managed to get replacement tvs! We have consumer protection in the States, but it’s generally enforced state by state, and my tv’s over a year old. I suspect that will be outside of the statute of limitations for a consumer complaint. Doesn’t mean I won’t be sending them a letter, however. . .
To Carolyn,
I have a couple basic suggestions for you. You could order a new board if you are uncomfortable with messing around with the old one. I am not sure cost wise how this compares to having a repair shop fix the old board. In my investigation I found the cost to be around $100 for a re-furbished board, $250 for a new one. You can get the part number you need right off the board. Taking out the old board and installing is very easy. But, if you are still uncomfortable at this point, you could try hiring someone to do that part of it. I am a handyman and have had people ask me to do all sorts of out of the ordinary things. Maybe you can find someone like me in your neck of the woods who would be comfortable with it. It is a very basic job so any confident handyman could handle it. Try calling a few and see whay they say. Take lots of pictures of everything first so you have as a reference before anyone touches anything. Anyway, just some thoughts.
Thanks for the great post. My LNT4671FX kept taking longer and longer to turn on. Replaced 2 2200uF 10Volt with 2200uF 35 Volt. Much larger physically, was able to seat one fully against the board 2nd one is sitting a little off the board. No chance of the leads touching anything. Powered on instantly!!!!!!!!!!!!!!!!!!!!!
Greetings everyone,
….. any ideas anybody..??
wonder if anyone can help. i have a samsung le40 R87bdx tv. with power board bn44-167A. I had the dreaded no start up and just the relay clicking. mine wasnt progressive it kinda just happened overnight. i replaced 7 capacitors in board.kept mostly same voltage but had to uprate 2 of them. BUT alas, still just clicking
apreciate ANY help
To Sam,
Thank you for the suggestion. I put a facebook call out to possible friends with electronics knowledge and I got very little response. Apparently I don’t run in such a circle!
What I decided to do is just trust an expert. i am going to have the tv evaluated by a knowledgeable tv repair store that I have worked with in the past on tube tvs, and I trust them. They are also familiar with this problem and indicated that it’s not just in Samsung tvs, which I find interesting. I’ve seen complaints about capacitors that they are Chinese made and are not the highest quality. I suspect more companies than Samsung used those capacitors. Perhaps this is an industry wide problem.
Anyway, I’m going to let these folks take a look at it and see what they can do. While he’s working on it, I’d like him to replace ALL capacitors and replace them with better ones. If he says I need a whole new circuit board, then I will take it to the Samsung recommended repair place and let them get me the part from Samsung (which should be covered in my extended warranty). At this point, I suspect my low-key tv repair guy could get this done for me economically.
I still want Samsung to pay for everything, and I’ll write them a strongly worded letter. (Ha!) Eh, I’m pretty good at letters. . .
HELLO Carolyn
POST YOUR SAMSUNG LETTER HERE WHEN YOUR DONE ,, AS I DID AND SAMSUNG DID REPLY BACK TO ME WITH TIPS TO HAVE MY POWER LINES CHECK THAT COMES TO MY HOUSE ,, STUPID ASSSSSSSSSS’S
LATER
Just wanted to add my voice to the case against Samsung!
My 40 inch LE40R748BD finally gave up the ghost last night. Contacted the retailer (Comet) who charge £30 for a call out plus £44 fixed charge repair plus parts (which shouldn’t run to that much having read the various comments!).
I’m reluctant to do the repair myself because it may invalidate any case against Comet/Samsung. FYI, I managed to get two brand new cars out of Ford a few years ago which had a manufacturing fault, so a refund on this repair should be a walk in the park!!
Greetings
@chris morris
on my power board i changed all 7 of the caps. i noticed that i used the same as you on all the 1000 x 10V x 105′c( al elec caps)
but on the 1000 x 25V x 105′c i used an fc radial capacitor (RS No – 315-0619)
In your expert opinion ( or anyone else who can help) does this make a difference???…could this be why i am still clicking..????
HELP……
@Neil FF
Firstly I’m no expert.
I don’t think the type of capacitor used in this instance should make a lot of difference, in any event 315-0619 as far as I can tell is an Electrolytic Capacitor.
I’m sorry I don’t really have any further suggestions for you.
@ Chris M
ok, cheers for response mate, i am gonna try and change them anyway. for what it costs it could be the clincher.
keep up the good work.
Thank you very much for this posting. I have a 22 month old L-NT4665F which had exactly the same problem. Two of the capacitors had convex tops. I spoke to Samsung customer service (several different people) and they all told me that there was nothing they could do. Their best suggestion was for me to pay for a diagnostic test by one of their approved people and then they might do something, but no guarantee. I had to buy a soldering iron and a few other bits but the actual cost of the replacement components was $2. A bit of nerve wracking soldering later and my TV works properly again. Before this I would have recommended Samsung to anyone. Now I will never buy a Samsung product again. I am amazed that Samsung is prepared to lose future business for such a cheap and easy fix. Thanks again
I have the same issue. Anyone know of a class action lawsuit?
Is this Bob Barry in the States or over seas? I need help in California.
Hi Kathy
I live in England and have tried to bring it to the media attension through tv and news paper without success So dont know what to try next.
Reference my post on the 14th – Comet repairman has been today and changed 4 capacitors (rated 10Volt, 1000 microF, 105 degrees C). He used 16V capacitors as replcaments. New power supply would have cost approx £80. Total cost was £30 call out + £44 fixed labour charge + £4 for the capacitors = £78 (approx $130).
I have a 40″ Samsung LE40R88BD LCD TV, I have had the same problems, Tv would not switch on, just the clicking noise, I took the back off and could see 2 of the bigger capacitors were bulging -I replaced them but no difference, I have now replaced another 3 1000uf capacitators and now have backlight and sound but no picture, should I change the 3 very small 47uf capacitators, any help would be greatly appreciated as Samsung and Curry’s are a complete waste of time and I really could do without forking out a fortune to get it repaired.
Hi Tracey
Not sure why you think Comet are a complete waste of time – this hasn’t been my experience but you’ve now got a real catch-22. Change the capacitors and see what happens but with no guarantee of success or call Comet. However, Comet may refuse the repair if they see you’ve had a go yourself, in which case they’d insist on a new power supply which would cost you circa £160. If it were me I’d have one more attempt to repair it myself, what have you got to loose?
Thanks for your reply Neal, I am trying one more time as like you said I have nothing to lose, I have gone from nothing except the clicking to the Tv now powers on, I have sound and a strong back light but still no picture, I am now going to change the small 47uf capacitore as it cant make it any worse. It was Curry’s that have been a waste of time not Comet, they deny any fault with the Samsung TV’s even though I sent them about 15 links and told them I could send a lot more of different forums reporting the fault, they passed me through to 5 different numbers before I even got the “no known issue” answer and wont do anything unless I pay for an engineers reoprt which is slightly less than it will cost me to get it repaired and then there are no guarantees so again your right I am in a catch 22 and Curry’s know this.
My next step is to email everyone in my address book the issues I have had and links to about 10 of the forums, I am asking everyone to email it to everyone in their in address book’s and ask them to ask their friends to keep emailing it on but copying in Curry’s and Samsung as I feel this is the only way I can get some satisfaction, (knowing I am letting other people know before they buy a Samsung.
IF ANYONE WANTS ME TO SEND THEM THE EMAIL FOR THEM TO START FORWARDING AROUND AND I HAVE CC’d DIRECTORS OF THE GROUP WHO OWN CURRYS AND SAMSUNG DIRECTORS PLEASE EMAIL ME ON Traceytom16@aol.com AND I WILL FORWARD IT ON TO YOU.
Negative publicity and lots of it is the only thing that may make them take notice.
Thanks for such indepth guide to this problem. I have just replaced all the 10v 1000uf capacitors on my 40″ LCD and it is now working like new.
Thanks so much i have now saved a fortune on repair costs
Thanks for the info. My TV broke this weekend. I told my husband about this post and sure enough we opened the back and two capacitors were bulging. We got the replacements and installed them and the TV is working fine now. I called Samsung and like everyone else was told since it was a wear and 1/2 old they would do nothing. Repairman was charging 150 just to come out and look at it. $8 for new capacitors and it is working like new!
Hi
have read this and numerous other web threads. It is obviously a relatively common problem but Samsung are denying this! When I sopke to the escalation team, they said if there were problems, they weren’t aware of them and that people should ring and let them know.
This is the number for Samsung UK customer services 08457267864
Excellent advise. My Samsung is 52″ LCD and has the same clicking problems and would not come on now at all. it just over 1 yr old so am out of the warranty. I’m not Tech Savvy but will try the suggested solution, the Pics and explanation are clear, however, should I freak out in the middle of it if by any chance you live in London could I solicit your help even for a fee? I’m sure it will be more reasonable than the expensive authorised repairers.
Allan
I live in south London, if you get stuck let me know. No fee required, I’m no expert but my repair was very straight forward and took half an hour. Good luck
I contacted samsung uk a couple of months ago they denighed there was a problem then thats why i tried to contact tv and news paper about the problem but no one wants to listen so what can be done?
My Samsung LN40A550 started clicking and taking a while to come on yesterday. This was on my mind all day at work and then I found this site. when I got home I opened up the TV and noticed the two bulging caps on the PS board. I removed the board and took it to one of my friends who is a tech who repairs circuit boards. He replaced the two caps in about 2 minutes. Took it back home and once installed the TV WORKS FINE!!!!! Thanks so much for your post:)
I have a 52″ Series 5 samsung LCD. It started clicking yesterday. I pulled the 2 1000uf 10v caps and a few others only the 1000uf caps were faulty the others are still good. Just replace the bulging ones. I found the parts at Fry’s Electronics. I own a digital cap meter and only those 2 are bad you don’t need to replace all caps on your power supply board. The parts cost be $5 and I’m back watching TV again. Also I would increase the voltage on the electrolytic caps to 16 or 25 that will keep them from having issues. The caps samsung chose 10v are just too close the voltage on those 2. They probably wanted to save cost so they went with the lower voltage caps. That is just a max voltage so as long as you get he UF correct at polarity the shaded area lines up with the – sign on the caps. The longer wire is always positive on the new caps.
