Need Help with a 27' Magnavox

pman2008August 24, 2006

Whoever can help. I need help with fixing the following Magnavox TV'S:

1) Model# (RP2748-B101) Chasis (27X102-00AA).

This TV turns on and runs for about 10 to 209 minutes and then it shuts off. Then after it cools down for about 5 minutes it turns back on and then shuts down in 10-15 minutes, etc.

2) Model# (25TSC6-0101) Chasis (25B501-00AA).

This TV doesn't turn on and just kind of makes alittle bit of a humming sound.

I would appreciate it if someone could help me pin point the problem...

Thanks Paul

The first one sounds like a problem with the B+ regulator. Most likely to cause this is a filter capacitor. This capacitor is on the B+ line of about 150-175 volts.
