The set is in sos, or shutdown mode. It shuts down after operating for 2-3
seconds. After numerous cycles, i have determined that it has high voltage,
audio, h sweep but no vertical sweep. Aftr preliminary tbs, i swapped out
the vertical ic, la7838, to no avail. No bad solder in the area, vertical
supply voltage ok, yoke ok.
Any suggestions? I don't have a schematic, btw.
