I have an old mitsubishi tv. It's hooked up to cable. It worked fine this morning. When I turned it back on this evening, all I have is a screen with a dark band across the top, white in the center part of the screen, and a dark band at the bottom of the screen. Nothing is showing on the display. Is it dead?

your tuner card is likely shot, not worth fixing

Try with the Mitsubishi remote the soft restart, set on Menu,1,2,3, and enter.

There's something wrong in the power source of the tv , very bad sign on a tv just 2 weeks old. Just take it back, not worth the hassle.

There was a software update early this morning which caused your recvr to go to recovery mode until it downloads the new software which takes about 4 hours. Once this is done you should be just fine!

Easy...first connect the hdmi cable between laptop and tv. Press and hold the 'fn' key on the laptop keyboard - bottom left corner. while holding the fn key, press and release the F4 key. This will toggle the laptop between its multiple display capabilities.

Press and holfn - press and release F4 until you get an image on the big screen.

Enjoy :)

Blue screen of Death?
No, this is not windoze.

can you change channels?
a blue screen usually means that you don't have a signal.
Is it hooked up through dvd/vcr player?

Try a straight connection to cable or antenna.

If it remains, then it requires surgery.

if you have warranty work they will direct you to the service center you will need, I do not know of any bb that service tv's.

Same problem, worked fine this morning and then tonight I million green horizontal bars - sound is fine. I think from reading up on this we are doomed. I am so pissed, the TV is not even 2 years old.

This looks like an internal fuse has blown, or a problem with the start up circuit. It could be just a small mains transformer about 5 cm cube in size has a fault. They have a built in over temperature cut out which may take half hour to reset.
