My technics amplifier su-g86 started by clicking off and leaving no sound. Now it turns on, but has no sound. The speakers are hooked up and everything else is fine. It just clicks off periodically and now no sound, but it turns on and lights up

Most of the time this problem is caused by bad solder joints.
All the units I have repaired all that was needed was to reflow the solder joints.
The most common place is the leads of the hybrid IC.
Usually there are very very fine cracks which can barely be seen with a good magnifying glass.
I usually go ahead and resolder most of the solder joints related to the output section.
Basically the mechanical stress of the heating and cooling causes this as well as the manufacturer trying to use as little solder as possible.
Hope this helps,

This unit uses a hybrid amp ic RSN3305 which is probably faulty. These can be purchased for $65.73 from tritronicsinc.com
