Apparently there are hundreds of plasma sets from this era that die in the same way - no picture, 10 blinks. Hopefully there are only a few root causes to explore.
When the set is first plugged in, I believe I get the normal 3 relay clicks - two quickly and a third after ~15secs. The LED is no flashing at this time. When I push the power button, I get some relay clicks, the fans power on for just a second before the set shuts down and the LED flashes 10 times repeatedly.
Holding the power button down does not get me any further.
I am trying to follow the service manual, which has great schematics, and board pics, but does not provide diagnostics or explanations of the power up sequence. For instance the code table pg26 lists 4 SOS conditions associated with a 10 blink code:
Sub 5V SOS, Main 3.3V SOS, DTV 9V SOS, Tuner Power SOS, all with the check point being the DG board.
It took awhile to realize these 4 conditions come from different places, possibly different boards.
Some of those SOS conditions are come from the P board, some the H board, some the DG board.
I would have thought that for a power problem I would first check the power board. Is there a way to verify the power board operation without the other boards attached, or is this not practical?
