SOURCE: Display backlight problem
i have the same problem, i thought it completely blacked out, but i realized it was just the main backlight. i can see it if i hold a flashlight to it, but i tried everything to fix it, and ive had no luck.

Sounds like it may be the backlight ballast on the inverter. Hopefully you are still under warranty, Call customer support even if you are out of warranty and explain problem.

There is no back light in plasma TV, Base on the description, the Z Sustainer board is bad. Replace the board will fix the problem.

Check the DC filter caps in the power supply first. Check the 24vdc (or 18vdc for this 22" model) to see if it goes away when the screen goes black.
There are main AC fuse, backlight inverter fuses, T-CON fuses.
