Hi All
I've got this 55" that flashes on power up but then goes dark.
The red indicator light comes on steady when I apply power and the screen flashes on and I can see a graphics box that says something (looks like a typical blue on grey Panasonic message box) then th screen goes off (lamps off) and the indicator light begins a sequence of a single flash followed by a one second pause.
I've attached pics of all the boards and I've started with the main board, I have 5V on the SRV-5V test point but nothing on SRV-16V and SRV-400V can be as high as 210 but continues to drop, as if it was on it's way to 400V when shutdown occurred and is now bleeding off.
Since I can briefly see a picture with a defined graphic can I assume that my main board and TCon are OK?
I pulled the lines that go to the lamps off the second power supply board but the aymptoms didn't change so I don't think it's a short or problem with the lamps.
Does anyone have suggestions and or a service manual?
Thanks
