There is a 1ohm resistor on the 4x4 pcb as soon as you take off the cover. ( I forget the ID # ) It supplys the -15volts to the control bd. The resistor will not looked burned. It was under rated. An ohm meter will find it ( open ). Rreplace it with a 1/3 watt. I believe the orig. was a 1/4 watt.

the above is correct but you need to have the dvd player on with no disc in so "no disk" is shown on the front display. then hold down the stop button for 5 secs to reset the display mode back.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
