However, If I hit the top of the tv hard the picture/sound will return. Sometimes it'll come back on its own. This is not a consistent problem (but often). Sometimes turn tv on & works fine. The picture and sound are excellent except for the problem. Is there a fix for this? Could dust have gotten into the tv? I noticed when I moved it - there was lots of dust behind it.
Dust is not the problem.they most be an open cecuit on the cecuit,just open the tv and look persiently if u can fine the open cecuit and resolder it with a soldering iron if only u can do it but if u can't take it to a qualify technicien

Most likely the volume down button on the front of the TV or the switch that it activates is sticking. Should be an easy fix otherwise.

The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

I have a similar problem on my CRT computer monitor (AcerView 76c). It is an old screen and I think it is just at the end of its life, much like your TV. Having some background in physics, I would be pretty sure that the problem is with the cathode ray tube's vertical deflection system. The horizontal deflection electrodes are working while the vertical one is not. This results in a display of a single horizontal line (or in my case, a few superimposed) in the centre of the screen. Where both X and Y (horizontal and vertical) deflectors fail then the electron gun firing would result in a single bright spot in the dead-centre of the screen.
So really, we have no choice but to move on and buy a new set as repair is probably just as, if not more, expensive than replacement with a new device. Seeing as your post was in 2007, I hope you managed to solve the problem.
Best wishes,
