I picked up a 46" Samsung LCD from a friend who had upgraded. Well, it worked great for about 1 month. Then every now and then it would do the "clicking" on power ON. After a few seconds it would turn on. Fine, I can live with that. Then one day it just started clicking and never stopped. So, I did the research and read a majority of the posts here and elsewhere. I took the back off the TV, removed the metal protective cover to reveal the board(s) and VOILA, blown capacitors. Well, no shock really after reading all the issues that Samsung has had with these boards. But, I bought it used and figured that Samsung would laugh at me if I even asked for a replacement.
So, I bought a refurbished BN44-00166C board off the web from a reputable company and had it shipped here. I installed it on 3.29.2012 and turned it on. Perfect. I watched TV for about 6 hours just because I could.
Anyway, my roommate left a note on my laptop this morning that around 2am the screen went black, but the sound is still on. It still flips through the channels with AUDIO ONLY, no video, no grey lines, no nothing.
So, I did some more research here today and found the backlight issue. So, I hauled the back off again and all the capacitors look perfect, they should, they were only used for about 9 hours!!!! All wires were in place and nothing out of sorts.
So I turned off the lights and grabbed a flashlight. Well, how about that, I can see the picture VERY dim if I shine the flashlight on the screen.
So, now what? Its not the board, its getting power, it sorta works, what is the solution to the backlight problem?
