I have a 26" Sanyo

I have a 26" Sanyo TV. Its about 9 years old. As I was watching, the screen shrunk to a 1/4 line across the middle of the screen. What might this be and is it worth fixing?

The vertical IC either has bad connections on it or hit has failed completely. These are common ICs and are available for about $12-$20. If you can solder, you should be able to repair this yourself. Open up the back and look for a small flat IC with about 11 pins attached to a heat sink. It will be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC. If you have any question about whether or not you have the correct part, post the marking here and I'll confirm the part.

Keep us posted.

Tv screen is black except for 1 horizontal line of color


The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

CRT TV with only a horizontal line through the center of screen.


Hi,

Yeah. Unfortunately you are right. It is normally the ic that controlls power to the gun. And it is expensive.
Your only chance is to find another model of the same TV that some is ready to trash or throw away at low cost and that TV having some other defect. Advertise in the local newspaper or other channels. It is worth a shot.

Tv not working


this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
