Question about Televison & Video
No sound is probably because you're not on the right input but the horz line is a failure in the vertical circuit. Could be the vertical Ic itself Ic401 (LA7833) or the feeder caps just in front of it... In either even it in itself not an expensive repair. Be aware though that's an old unit and it is likely that several caps going bad through-out the unit. Make sure that you ask the tech to go through the unit with an ESR meter and test all the remaining caps in the power supply, horizontal, HV and regulation circuits. A little preventative and that set will still be running long after I'm dead and gone...
