While watching TV screen went blank. Voice stayed on

Have you tried replacing the cable? They can cause all sorts of trouble.

Is it possible the timer was accidentally set???

Aside from checking the fuses it likely will require a technician or a shop to examine the set to see what is wrong and what needs to be replaced.

Sounds like a power supply issue but that would need to be checked.

Maybe the plasma controllers are gone.

Any luck getting this fixed?Please let me know.Thank You very much!

i would suspect the Y-SUSTAIN board as the problem they can fail and the tv will stay on with no video. they way to verify would be to check fuses on the board they are usually white and look like traditional GMA fuses usually located near connectors for power.

if you see the volumn bar on the screen when you adjust the sound then the tv should be OK. So look for HDMI wire not inserted fully or what ever wire sends your info to the tv from your cable box, satelite box, or whatever. Or does anything show at all on the screen that you can see, like snow on antenna without a signal input. Maybe a real problem.

Tries unplug,replug about 1 hour later,if doesn't work,than Ur main video backlight board it dead,must replaced.

I repaired mine. It had the same problem. Could be power supply. If you open it then maybe I can help.

tha same problem
