Default Old Magnavox TV, no picture RH8520
In article ,
says...
Hi, I have an old 46" Magnavox TV model RH8520 AK08. The video just
stopped working the other day. Audio still works fine. It turns on
and off ok. Does anyone have any ideas what might be causing this?
Maybe the light source?

These sets have CRT's. Most likely the high voltage has quit, and
there are numerous possible reasons. Bad flyback transformer,
focus bleeder breakdown, cracked solder joints, protection circuit
shutdown from over voltage, over current, loss of vertical scan...

You need a tech familiar with the set and armed with schematics.
Learning curve is very steep for anyone not familiar.
