Unfortunately, P/A does not release schematics - even to repair techs. You have to find a knowledgeable repairman, or ship it to P/A.
1-888-990-1236 for support, and RA# info.
Plan to be without your amplifier, as NEW WARRANTY repairs are backlogged approx. 6 mo.
Rule out external problems by hooking it up to an isolated bench power supply.
If planning on doing your own repairs, see this site for info.
P/A has an ONLINE SUPPORT WEBSITE to order parts etc, and may be a useful resource as well. Do some fishing, and you may find what you're looking for.
I will too, and post any findings.

Make sure your head unit is off.
Reset the amplifier using the manufacturers specified method. Usually this is just power down briefly and then back up. I usually pull the amp fuse and make sure all LED's on the amp go out. Wait 10 seconds, and then put the fuse back in.
If the LED comes back on when you reconnect power, without the HU being on, you've got a bad amp.
If the LED does not come back on after reset, then check for short circuits on the speaker leads. Still leaving everything off, from the amp terminals, remove both wires to a specific speaker and check for shorts.

That means that 2 wires must have touched and the protection light came on to prevent further damage.. There is usually a reset button somewhere on the amp and pressing it should reset that light
