Check the transistors under the aluminum strips that are screwed down, if there burnt you can replace them(it usually smells real bad when there burnt, you can smell them when you open up the amp. When mine blew, I just replaced them and soldered the new ones on. Make sure you replace all of them though with the same model#.

It doesn't smell though.
And when you turn this amp on, it turns on and clicks into protect and then back to on and keeps going in a loop
