You should be able to use a universal remote that you can purchase at any store with a decent electronics department. You can also try online.

The problem might lie with the TV itself. The optical input might be switched off. You can check if the signal is coming out of the TV. With the optical lead plugged into the TV and the TV on. But not plugged into the Amp. You should see a red light come out of the unconnected end. If you don't see that the socket is switched off at the TV end. It might come under sound in the menu, or options, or digital audio output. Or a combination leading to the other! If you see an option for Dolby Digital, set that to on as well. Some HD TV channels use Dolby, but others don't. It will only come on with certain films and TV shows though, it should switch your receiver to the Dolby setting, just like DVD and Blue Ray discs do.

Hi Its in protection mode .. check your speakers cables first if is all OK then the receiver needs to be serviced the power supply section has a damaged parts or re-soldering the points again , but mostly damaged parts due to age of the device. hope this helps Kind regards M.Mathis

Generally, you put it in the tape in/out connectors.

Yes but you will more than likely have basic control. Unless you get a custom programmable remote. Depends on how much you want to spend. I'm sure Amazon or Ebay will have the factory remote.

Check speaker selection switch. If set properly then perhaps the amplifiers are blown - check for fuses that may be open.

It is sensing a short circuit remove the short circuit probably the speakers to be disconnected and the receiver to be powered on if it does not turn off you have localized the short circuit

Sounds like DC leakage....pre-drive and/or output transistors (or IC) becoming intermittent often pass DC voltages to the speakers. The "pops" you hear are these DC pulses being passed to the speakers and the "cutout" is the protection circuitry doing its job...protecting the speakers. Speakers want AC voltages...plus voltages moving the cone in one direction, and a negative voltage moving it in the opposite direction. DC voltages push the speaker cones in a single direction and hold it there until it fails. The bad news...it's repair shop time.

There is a short either in the power supply or one of the output channels. Receiver is shutting down to further protect other components. Needs to be serviced. Check if the warranty is still valid since they usually last about one year
