Question about Cell Phones
Make sure screen is clean from moisture/oils from fingers...if still not resolved try rebooting by holding power button selecting turn off then wait 30 seconds and turn back on...if still not resolved if there is a battery turn it off again remove battery press and hold power button with battery out then put back in and restart it...if still not resolved is there a screen protector? Has it worked before now? Are your hands dry or callused? May need to get a stylus pen for touch screens just be careful not to press hard with these as the rubber collapses to the point the metal edge can scratch the screen protector or screen...hope this helps

Generally speaking, an amp protects 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.
