Question about Televison & Video
This is a problem with the vertical circuit and can be either bad connections at the vertical IC or a defective IC. This is a common problem and is easily repaired. The vertical IC is a small flat IC attached to a heatsink with about 11 pins or so. It might be marked LA7837 or something similar. If you can solder, try resoldering the pins on that IC first. If that fails to resolve the problem, replace the IC. Expect the IC to cost about $15-$25 depending upon the exact one. It is possible that some of the capacitors in the same circuit are defective as well. Once the IC is replaced/resoldered, report back here with the results and we can go further if necesary.
