Re: Samsung TV

Just an update really and posting so it may help others, my tv still had the same problem of randomly shutting of my display, while still playing sound. So I took my tv apart and checked the circuit board for dry dry solder joint, it turns out, I have two faulty joint which happened to power the main control board of my tv. So it works now, I was a bit worried that id blow something when I fixed it, but it works fine now. I have included a pic for reference....

Re: Samsung TV

Not sure, there is still around another 5 Samwha caps left, it could still be there is another
faulty cap on there. So far the problem rarely happens now, it use to occur after 1 hours of use, now that's about 6/7. When I used to turn the tv off, id have to wait 5 mins, and this would give me another 40 mins of tv time. Now I can turn it off for a minute, then I'll have another 5++ hours before it happens again. There also used to be an electrical discharge sound, kina like a crackle, as far as I can tell this has gone too. Since the swap it happens very rarely...

Re: Samsung TV

Dam it, my tv did it again.
Only this time, its not as freqyuent, I need to buy another 4 caps.
Should of replaced them all, oh well will order next week.

Re: Samsung TV

Well I replaced all but two of my capacitors,one of them I replace a 2200uf 10v with a 2200uf 16v, I made sure all the caps where 105C and the correct ratings. My initial problem was my tv screen kept on going black with the sound still coming through my speaker, it would do this randomly, so it made it hard to watch anything or use my computer. Since my fix, it works perfectly, there is no problems at all. I`m actually buzzing with the fact that a £8 capacitor buy has saved me at least £130 repair bill or worse £500 for a new tv.

The bad caps were...

Re: Samsung TV

Thanks, Ill give it a go at the weekend and see if it fixes my problem as
my tv screen randomly shuts off only leaving sounds, Iv tested too see if the screen in on but its completely off so its not the backlight.

Hi, I have just recently ordered some capacitors of this site, now they are the correct ratings, 1000uF 35v ZLH 12.5mm 20mm but the wrong size. Would this actually matter ? As I want to replace all the capacitors on my power board, I have heard bigger capacitors have a lower esr, does this just mean they are less likely to overheat ? Anyway, here is a pic of a capacitor on my powerboard. that I will replace, as you can see they are much bigger than the ones I have ordered.



Thanks for your help
