Make sure your speakers and speaker wiring is the correct impedance and not shorting.
Ensure there is plenty of clean fresh cool air for the amplifier.

This device does not have an internal tuner. It is simply an amplifier. The buttons on the front labeled TUNER - TAPE - PHONO - DAT/VCR 1 - VCR 2/TV are selector buttons for additional components that hook up to the respective connectors at the rear of the unit. If you want to play a radio with this device, you must buy a tuner and attach it to the tuner inputs in the rear of the unit.
You'll need 4 connections total. On my integrated amp, I connected the four connections to all Line In and Line Out ports. And the other ends into the tape 2/EXTRA ports respectively.
your voice coils in the speakers could be damaged (i have had this happen on my stereo just from age), but it is more likely that the amp itself has been blown and needs to be replaced. if you are good with electronics you could open it up and see if there are any charred parts or burst capacitors.
There are bad solder connections inside the receiver that are causing the protection circuit to kick in. This is a simple resoldering job and should only cost the labor rate at a local service shop.
