Question about Dell W4201C 42 in. Plasma HDTV
I am trying to tackle this myself. any input would be greatly appreciated. not very old 42" Vizio P42 EDTV - they say is plasma but ooks like lcd to me. just out of warranty - now has black screen - BUMMED .... i have sound and can change channels - but no picture no on screen instructions no snow. :-( same problem. I have a dell 42" HDTV plasma.
First thing to check is if the back lighting has just failed... Power the set on and looking across the screen can you see a shadow of a picture happening? You might even use a flashlight to shine directly at the screen while you look at it from an angle.

it could be 1 of 2 things, the panel could be shorted or the logic main board could be out, you must open the back and take voltage measurements, check the panel voltages and then start pulling the connectors off one at a time, to see if the voltages come back up
