Panasonic TX-P50G10B - Not turning on - Red Light 3 Blink Error
I've got a Panasonic TX-P50G10B Plasma which blinks red 3 times when turning on. I tried changing the power board however that didn't help, and upon further research I found the manual for the TV which said the A (AV) board is the suspect. I changed it with a board from eBay however the problem persisted. I assumed it was a bad board so returned it and bought a new one.
I fitted the new one today and the result is different;
- Before: Plug power in, press power button, TV tries to boot up (green for a few seconds) then 3 red blinks.
- Now: Plug power in, press power button, TV is in standby (solid red). Pressing On with remote turns the light to flashing green then green, no picture (or noise of TV turning on). Holding a TV Vol button whilst pressing On button tries to boot up TV and then the 3 red lights blink again.
So I’ve changed the suspect board twice now, and still have a 3 light error, with slightly different results.
Could it be?
1) Something shorting the board somewhere else in the TV which has broken the 2 new boards as I put them in.
2) Both boards have been bad.
3) TVs just busted.
Thanks for any help.
