I OWN AN OPTIMUS STEREO REVEIVER STAV 3400 professional series which I need a manual for. can you help me? on the back of the receiver are the numbers 310-3025, i HAVE ALREADY CHECKED WITH RADIO SHACK WHERE IT WAS PURCHASED ... NO LUCK.

google Optimus STAV-3770 remote
several offers on line. eBay has several starting at $6.00

Your best bet would be to call Radio Shack Customer Service at (800) 843-7422

Just Google Optimus STAV-3350. One of the first items listed will be access to Radio Shacks documentation for the system.

unfortunately most stereo mfgs. install a protect (shutdown) citcuit if it detects an internal short (bad amplifier )or a external short( bad speaker)....disconnectl speakers see if it still shuts down if so there is a genuine component failure inside..however if it stays on then in all likliehood its a bad speaker

Buy a universal remote, program it manually and try the Yamaha codes first.

Optimus was sold only by Radio Shack. It would be a special order. Get the catalog # from the rear of the receiver (31-XXXX)

Most often it will require an output IC, but I have seen it be a bad ground or a transistor in the protect circuit.
