Can you fix a receiver?
The procedure varies from manufacturer to manufacturer, but most protection circuits can be reset by unplugging the receiver, waiting 30 seconds or so for the capacitors to discharge and plugging it back in. (Make sure to turn the volume down!) As long as nothing is shorted out, your receiver should go back to normal.
How do you know if a fuse is blown on a receiver?
Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
Why did my receiver stop working?

What can cause an amplifier to short circuit?

How can a multimeter help you find a short circuit?

Can a short circuit be mistaken for an open circuit?
A short-circuit should not be confused with an open circuit, in which current does not flow at all. Though the symptoms of a short circuit can be similar to an open circuit, diagnosis is a bit different.
