Question about Audio Players & Recorders
Sounds like either the main power fuse is blown,or the power transformer is bad. If the fuse is blown, probably means the amp is shorted.

This unit is most likely in protect mode. This occurs when the receiveer detects a problem with the output amplifier section and that section is disabled. The most common failure parts are the output transistors. Expect a parts cost between $15-$40, Add in the local labor rate for the total repair cost.

I am guessing that the ceramic resistor is close to the output transistors. I would also guess that one or more of the output transistors has shorted. This causes a high current draw that is blowing the fuse. You could also have a power supply problem. The ceramic resistor is a .22ohm dual emitter resistor that is used in the output stage. The transistors located close by are probably shorted and should be replaced. Start there and let us know what happens once the transistors and the resistor are changed.

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 'nekkid'. 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.
Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.
