VISIO Model VP50 HDTV 20A (screen dead)
VISIO Model VP50 HDTV 20A
I know something like this has been covered time to time, BUT!
Can anyone shed some more on this for me.
I have no inputs going into the TV, just power.
This is what happens.
Plug in and push power button, the power light on front goes from amber to green and stays on.
The screen does not light, Black, Black (Dead).
I removed the back, this is what I see, all capacitors look new.
Checked all ceramic fuses with VOM , all are good.
When I plug in the power cord, relays on the lower right power board (double click).
When I push the power button, again relays on the power board (double click) followed by the
logic boards LED lights 2000, 2001 and 2003 lit up, a second later logic board LED 2002 lit up
for a second and then all the logic board LED's go off and the speakers pop, followed by
LED #1 on the power board starts to blink continuously.
I have tried unplugging X and Y boards from the power supply, one at a time then all with the same above results.
Guy's any help on this would be appreciated.

I upload the wrong picuture 
, guess the old age bug is starting to bite. The sticker is actually on the back of the plasma panel inside the tv. It may be somewhere in the upper left or right corner. How long does the tv run before the speakers give a pop noise? Have you attempted to check voltages? Is there a table on the power supply showing what led #1 would be. It seems the power supply is going into protection mode.
