SOURCE: no sound on right channel
Take a look if your outputrelay is switching on.
If so, then measure if the signals coming thrue.
Offcourse only if you are sure that there is a signal present.

Unplug the power, open the case and try to locate some electrolytic
capasitors is series with the audio at the channel with the problem. One
of them must be blown.

If you have lost the channel on all functions IE:tape, radio, aux etc. Then there's nothing wrong with the back connections. The good thing about stereo amps is that it uses the same parts for one channel as it does for the other. Which in your case means that the left channel can be used for a guide to the right. The first thing to do is look around the amp. Find the two channels parts and compare them, first by looking at them. If you find one burnt and the other good, you have solved it.
As long as you keep away from the power supply parts, you can touch them with an insulated screwdriver. A buzz means it's working and if you work backwards from the speaker section, poking parts with the screwdriver you should be able to find the cause of the problem. Remember use the left channel as a guide to what happens in the right.

Testimonial: "Many thanks for the advice!! "
I've suspected that your main problem is the output amplifier stage, since when you turned the volume way up you slightly hear the sound, meaning your pre-amplifier stage is working. The most common defect is the output Transistor/IC and its coupling/bias electrolytic capacitors. This kind of problem needs to attend by an experienced technician to confirmed where the fault is. Also, you have to consider bad solder joints in that area. This will do the same symptom if there is a cold solder/dry joints.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
