Check its backlight inverter board, and CCFL lamps. In most cased, the back-light inverter board might need replacement. Check all the CCFL lamps too for any black edges.

My Panasonic plasma tv is stuck on one channel. The remote has new batteries but only works for the volume. I tried changing channels on the set itself and now the screen is black


If the screen is still on but is black, try changing the channel on the set itself back to the channel it was originally on. If you can provide me with the model name of the TV (usually somewhere on the back of the TV), I might be able to find out how to re-set up your remote with it.

My sony bravia klv40ex600 won't turn on,the light indicator for power,volume and channel is on, the screen is still black


Hi, have you tried pressing the TV button that is under the On/Off button on top right hand side of remote control? Some times its possible to accidently press the DVD or VCR controls and this by-passes the TV as a remote?
Another cause can be a poor or low battery in the remote itself. If you have no luck let me know & we can try some more things, however, I have heard that The On/Off Switch on the TV can be a problem. Goodluck, Jon..

This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know

We have a similar problem when changing channels/surfing, the TV will begin to power cycle, until you unplug THE CABLE TV input, then it will turn on again and stay on as you rehook the cable and change channels....till it decides to do it again, DTV channels seem to trip it up, but not sure....if I leave it on the same channel it will run for days. Yep and the cable TV is grounded outside

You have inadvertently activated one of the closed-caption modes called T1 or Text 1. Find out how to turn the closed-captioning off and on and you'll be able to turn this off.
