check ur speaker wires, try disconnect all wires from back of unit and then try to turn on unit .

Trying to hookup XM radio to RX-397; no sound. Which inputs should I be using?

Anything that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input (except PHONO). Get a cable like the one described here: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10218&cs_id=1021804&p_id=665&seq=1&format=2

Of course, if your XM device has standard RCA outputs, use RCA cables without adapters.

Yamaha RX-770 Receiver display quit


there is a bulb inside the backlight on the lcd display.it is 12 volt and alot of manufacturers run it from the +- 15 volt preamp power supply,on the plus rail.when the bulb burns out it can activate the dc speaker protect,or some other 12 or 15 volt circuit..if it is a flourescent display that is a different problem.those run on 5 12 18 and -32 volts.there is also a 6 volt ac filament voltage.you need the schematic.
