Question about Pioneer Audio & Video Receivers
In my case, if I push in on the balance knob, I can get the channel that quits to work for a while.
This leads me to believe that the pot is dirty as opposed to a circuit or component failure.
A couple of years ago, I sprayed circuit cleaner into the pot as best I could and the problem disappeared but, it has returned.
My next attempt will be with one of the newer cleaner/lubricators that are available now.
I don't know if this will solve your problem but, it might be worth a try.
BTW, getting access to the volume/balance pots takes some doing. As long as you are there treat both pots.

Have you checked within the set, the fuse and if the standby circuit is working. thre could be a failure of this sub votage which is required for the switch on of the main power. If you do not have any standby indication you must check this section, however if you arre getting the standby you would have a failed output or a shorting that is triggering the error amp to swtich off. If you are familiar with the circuits you can check but I would suggest that since you will need more experience to look into the main board for tracing the fault. In such case check for the service centre nearest to the place you are in using a google search for Pioneer - Audio systems- sevice. Helpful I hope. Good day.

The relay buzzing fault is caused by a faulty electrolytic capacitor.
You need 47uF 100v 105C radial.
C52 on the corner of the board near some power resistors.
