Huge magnavox Combo roundie Warren MI
 

I own that as of today, it was tested by a fellow smarter than me, he said it has a bad thermistor and a weak green and blue, but can be brought back up slowly.
The player works and the radio did tune in when I got it home, however there is no sound in any mode, first of all where should I begin in this process of restoration?

radio tuned it based on the tuning meter?

does it have a remote, look on the back for a large metal switch

Yes it was moving and stabilizing as I moved the tuner on stations in my area and some I know where in Indiana as well it was able to pick up on the dial

on more what is your experience level in electronics?

yes it does have the switch, there are two of them

make sure you have the remote off.

speaker switch to internal

modern electronics fair to average this old stuff I know where the on off switch is lol and I do know basics

ok it is on internal and I can hear scratching sounds out of the speakers when I adjust volume but no output sound

pm me with your phone and I will call you gotta go off line for a bit but can talk

make sure your not on stereo, that is phono, select fm mpx

ok I sent my phone number to you I will check my settings

Can any one point out?
 

I have some pictures the thermistor is suspected bad where do I find it and how can I tell?

not on those pics, those look like signal pc boards. FYI I did see at least one likely electrolytic caps on one of those board that prob should be replaced. It looks like a paper tube on laying on the side, about 1.5 inch long and .75 inch wide. should have a + marking on it some where. Any of those are suspect.

if they leak they can throw off the tube bias and cause the tubes to pull too much current. you will need to locate and replace all of them. A Sams will help you find all the parts.

Maybe some more pics of the rest of the chassis.
