Something's been up with my TV for a while now but it's getting worse and worse to almost unusable.
What was originally happening is that the TV screen starts to pull up at the bottom showing just a black border at the bottom, and having shrunken picture between the point it went up to and the center of the screen (hard to explain really without seeing it do it).
- Hitting the tv a few times would fix this usually
- It could come back once in a while while watching or not do it at all some times
- It doesn't happen once the TV has been one for a while which might mean it's something to do with heat
Now what's happening which is even worse is that after the tv has been on for about 5 the entire screen will randomly shrink to just 1 line. Sometimes hitting the tv will fix it, today i've had no luck with that and am stuck with the 1 line after the tv has 'warmed up' for 2 mins.
I searched google and found this:
I don't really understand it though...does anyone think I could repair this?I don't have a diagram on this set, but from the symptom that you describe, you have a problem in the "vertical circuit". This circuit is what spreads the picture from top to bottom. Usually the first thing that fails, are the vertical filter capacitors. They will cause the picture to pull down at the top, up from the bottom, or both. They will also cause the vertical ic to over heat and possibly short. If it shorts, you will have a line across the screen.
