Question about Toshiba Televison & Video
TV was working fine for 10 years, a couple days ago picture went black except for a 1/2 wide horizonal line across the center of the tube. Audio works.
This is a vertical circuit problem that is either bad connections on the vertical IC or a defective IC. If you can solder, you can fix this yourself. Look for a small flat IC attached to a heatsink with about 9-11 pins. It may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace the IC. There may be defective caps in the circuit as well, but those don't usually cause complete vertical failure. If the picture does not return fully, update this and we'll continue on to the next step.
