Several possibilities come to mind. First shorted connections to speaker wires. Faults in the power supply. Sometimes if the unit has not been working for a while the large capacitors in the power supply can dry up.

Take the batteries out of the remote control, then apply a piece of black tape over the IR sensor, Unplug the power, wait a few minutes, now power the unit back up, does the unit still have the same volume high symptom? If so, remove the tape and see if the unit responds to any other commands(other than volume) from the front panel. If it responds to the panel controls, the processor is most likely good. very seldom is the IR transistor bad, if it is no input command will work.
Try fixing your remote controller, because sometimes when we neglected to replace our remote batteries for a while, it will leak and it will build up on the contacts of the remote pad.
Take off the battery, open the back of your remote, lift the circuit board, clean the green painted part with cotton balls slightly damp with rubbing alcohol as well as the black thingy behind your remote pad, let it dry put it back together, replace with a new battery and try if it works.
Could be the signal board has a bad cap, in this case it sounds like you are getting intermitten power to the inverters....when the tv goes down and of course you have audio....Shine a flashlight on to screen and see if you have a picture...look carefully. If this is the case..you have the above problem!
