Question about Amplifiers & Preamps
The amp sounds like it has a primary power supply failure and/or may be in protection mode. First, I would check for any blown fuses, replace any you fint with exactly the same type and rating. I can advise you here if you are not sure. If the unit blows a fuse after replace any failed ones, then there is a short circuit that you will have to trace out in the unit. DONT KEEP REPLACEING A BLOWING FUSE You generally are just doing more damage to the amp.
If all the fuses are OK and you are savvy with electronics and soldering, you could open it right inspect for these problems., and you have a multimeter, do some powersupply voltage checks, also check for that the main transformer is ok. Resolder any dry joints you find.
It may also (and or) have a problem in the output stages. Running it hard may have produced some dry solder joints, or blown a transistor in the output array. Happy to advise you further, just ask :)
