Question about Televison & Video
From 31" picture to 1"vertical picture for 5 sec then no more picture
Usually this is a problem in teh vertical circuit and generally results in a thin horizontal line through the center of the screen. If that is the case, look for a small flat IC that may be marked LA7837 or someting similar with about 11 pins. This should be the vertical IC. Try resoldering the pins on the IC first. If that fails to resolve the problem, replace the IC. Please note that defective capacitors in the vertical circuit can cause this as well. The more probable defect is the IC. Update this with your results. Also be aware that there are potentially dangerous high voltages inside the set even when unplugged.
