Question about Projection Televisions

1 Answer

I have a Philips Model 50P8341. About a year after purchasing the sound started intermittently going out. Seemed like when it heated up, the sound was gone. I simply turned the internal speakers off and bought a surround sound. Now, 3 years later, the TV start intermittenly turning off on its own. Then it simply would not turn on. I read a post regarding a small circuit board with an 80-pin single inline connector that would lose connection and cause issues like this. I removed the board, cleaned the connector with alcohol and reseated. Worked great for about 6 months. The other day I moved it to get something out from behind it and now it won't turn on. I tried reseating that same board - no luck. Is this worth repairing? Any clues?

Thats the small signal board. Check the solder connections on the main board where the connector is where that board plugs in Phillips has been plauged with bad solder joints in that chassis. The solder may have hairline cracks in them.
