Question about Audio Players & Recorders
The "switched off by itself" is indicative that the auto-protect is acting. Auto protect senses that there is something wrong within the unit and rather than the damage extend to other areas, it simply switches the entire unit off. On some models, this also hold true if there are no or faulty speakers connected to the receiver. In others, this happens when there is no intelligent signal received such as in FM when an antenna would be required.
If you have verified that it is not poor signal, speaker problem, then perhaps your best bet would be to seek the services of a qualified audio technician since this would involve electronic circuitry/component diagnosis, soldering and the use of a DVM.
hope this be of some help/idea. Post back how things turned out or should you need additional information.
Good luck and kind regards.

Generally speaking, an amp protects itself from heat, shorts and overloads.
Overloads can be from excessive periods of high output 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 hands-on tech.
