C2073 Transistor is hot on standby and the channel is silent. Why?

[SeanYB]

The power button of the device was broken and the fuse was burned. So, I changed the fuse, and then I directly connected it over the switch. It can be turned on and there is sound, but I accidentally found that there seems to be a channel that is silent. I changed the input terminal, but it still didn't work. Later I found that the transistor c2073 was hot.

I’m a starter. Does anyone know how to fix this? And what is the circuit diagram?

Are you referring to audio amp? what is the model number? posting name plate or relevant pictures will help you get right answers.

Many transistors normally run hot.

How hot is it? Can it "fry spit"?

It is possible that the hot transistor is a sign of the problem rather than the problem itself.
