I have a Samsung 55" LCD TV that is over the warranty. The model is LN55C630K1F and version is SQ01.
The screen start flashing like the screen get darker and flash quite bright at like 4Hz intermittently. At first I can change channel or change screen display and it will stop. But is slowly getting worst.
I had gone online and look for the service manual with no luck. I need to find the schematic so I can get into it. Anyone has ideas where can I find the schematic or have any opinion on what's the problem. I don't exactly want to open it blindly and probe and I am too cheap to call for service yet because being in field service before, the hardest problem to find is intermittent, I still cannot control how to get it flash at will.
