93 Toyota Camry

check all fuses and if you want pull the radio out and see if the radio has a fuse on it personally which most after market sony radios do so . what your checking behind the radio is the yellow wire to have constant 12 volts even with the key out of the cylinder if this wire does not that check all fuses and most likely the one in the engine bay cause constant power is usually fused in the engine compartment. so basically check all fuses throughout the car as well as in the engine compartment.
