I can not get my receiver to output sound to the speakers.

It did before.

The tuner does not work, or the DVD, etc.

Any ideas what to try?

The only real chance of fixing this is if it is a bad output selector
switch. That is not unusual tho. I imagine you are going to find the
entire audio output section is an IC on a big heat sink that you can't
find anywhere.
I had one of these on my desk at work (Pioneer) that I just hard wired
to the FM tuner because that switch was bad. It went out with the
trash when they took the office apart after I retired. There is
another one in the shop (Sony) with a bad switch that is probably
going in the trash the next time I purge stuff I am never going to
fix.
