Hi, i have a samsung tv lcd serie 5 from 2012 it have of problem that it turn on after some hours so, after searching, i found that i need to replace the capacitors on the power board but the capacitor looks ok, not blown or something anyway, i replaced 2/8 capacitors and the problem didn’t fixed and i got new problem which is the colors in the screen and blinking led 6 times every 1minutes for about 1hours(which is better than before that it was taking 4 to 5 hours to turn on) Another thing The motherboard have a lot of acid in the back of it, so, i clean it with alcohol 95% What i should do other than buying new motherboard or power board? Do i need to continue replacing the capacitors ? what is the reponsable components for that colors ? Two boards photos
Appreciate any help !
Hi M J, yes, you must exchange all of the capacitors. The capacitors can look fine, but inside the capacitor, there could be an issue. The electrolyte is having some “life cycle” and if the electrolyte is old, it can lose capacity or lose the right conductivity. The capacitors will work fine for about 2 up to 4 years, then they will start losing their electrical characteristics. The first step in any repair centre is exchanging all of the capacitors, except tantalums. If the issue will still continuing, write below, and we will try to find another solution.
