Try disconnecting the cable box and run straight cable from the wall to the tv. If it clears up it is the box. If it does not it is probably a horizontal or power supply problem inside the set. Hard to say without actually seeing the set. Thanks for using fixya.

I moved my tv from one room to another and when I plugged it back in, the picture stopped working, sound works, but no picture, one small line all the way across from left to right only appears, is there some type of bulb or flash that needs to be replaced?

This has been going on for about a year. I turn the tv on and frequently after a few seconds it goes off, leaving the red light blinking. I turn the tv on and off until it comes back on, then it does the same thing. Eventually, after anywhere from a few minutes to as much as a couple of hours, it will finally stay on and then it may stay on all day long. What do I do to fix this, and how much should it cost to have someone fix it?
