You may have speaker wires touching each other or a short circuit in the wire. "Check SP Wires" means to check your speaker wires.

minr froze and wont turn on now either has anyone had any luck fixing this problem?

SOURCE: Check SP wires

if you checked wire carefully in high ohm reading and confirm no internal short circuit.-please follow me:-1-disconnect all speakers cables from receiver and check if it is fine-try to connect your speakers one by one until you find the bad one.if it is still shut down you will have a problem inside receiver itself and needs service center to fix.
-it maybe speaker check it also one by one with good known cable.

The speaker cables are the ones that clamp or tighen down on the back of the reciever. All the spkr wires have to have the positive and negative leads correct. Also not aven one little strand of wire can be touching another conductor or you will have this problem. Make sure all leads are correctly ran and hooked up positive to positive and negative to negative from the back of the reciever all the way to the speakers. This should solv your problem.
