Bga Solder
Samsung Tv repair question?
I have a Samsung LNT4665FX with screen problems. I have replaced two caps on the PSB and got the tv to turn on. Now the screen will have lines in it, and then go dark. green blob in corner migrates towards center sometimes. The backlight is still illuminated though when screen goes dark. I tried to reflow solder on the main BGA chip on the main Audio/ video driver board. No luck. Replaced the main Audio/ Video board with a new one. Still no luck. Could it be the LCD controller board? I don’t know what else would cause this? What should I be looking at now, knowing the power supply board is ok and the main audio/ video board is ok? I don’t suspect the screen, but, you never know…
Thanks
Sounds like you are very good at repairs and probably have already tried, but many people open the back of the tv and reseat all the cables attaching everything inside the tv, especially the large main plug into the panel, and that sometimes it fixes the tv.
