It will turn on whe plugged in and the display turns on for about 10 seconds than turns off and there is no sound at all the amp stays on and i cannot turn it off without unpluging it any answers i want to give it to my brother who doesn't have a good amp
First I would try to reset it. With it off, hold the power button for about 5-10 seconds. It should either reset, or tell you to press enter to reset it.

Open it up, check by where the power cord comes in there should be a fuse. Check to see if it is blown. If so it is an easy fix. Replace the fuse with same type. If not the capacitors are gone and that is expensive to replace.

unplug it discharge output voltages with a 1k resistor then resolder the voltage driver ic's these ic's start with up, ie upc2558 , or stk350 etc. you will see the solder rings and cool solder joints around then. Use liquid flux and solder them back to the board. You might end up replacing them but youl never know until you try soldering them first. Larry's Electronics. [email protected]

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.

Something is heating up to a point that it fails in the rear amplifier section. take it to a tech.
