Yamaha HTR-5990 Audio no longer works

The signal that comes from most tv's via the optical output is a stereo signal only. That is what your receiver is reading. You would have to manually set your receiver to decode the signal into surround,.

according to yamaha website you have 2 hdmi inputs, and one hdmi out on that unit

You probably need to take that issue up with the setup of the unnamed device originating the signal.

Is it going into protect mode???
If so, check your speaker connections. Make sure there are no loose copper wires hanging out, and that your splices are clean at both the receiver and the speaker.

The RVA350 comes with this model according to the manual.

Hope this helps

Can you remove connection between the receiver and TV and then try ? If it still turns hums and turns off, then try disconnecting all the speakers and power it on. If it still turns off, then you have a bad receiver...Let me know..

unplug everything that is pluged into the reciever. plug the power cord into an outlet with nothing else pluged into it and try it again. if your electronically experienced you could try to ground it and carefully try it again. give the unit a smell, does it smell a little burnt? if you have a screw driver and a little trust in yourself tale the cover off and look at the board for visual burn marks there should be fuses inside the unit, you could check those out. If you dont see anything visually wrong and it is still not powering it would be a good idea to bring it in to an electronics repair shop and they could diagnose the problem. With the use of a volt ohm meter it would not take long.

You must be sure that you also have "audio" cables connected to the receiver to make this all work. As far as the TV is concerned, the same applies....accordianman

Did you ever get this resolved?  I have a similar problem, my video feed seems to work but I have never been able to get any sound from my speakers using this component.  I'm not sure what YPAO setup is but I just read a suggestion to reset the receiver to factory settings in the event something is programmed that causes the problem.

I JUST EXPERIENCED THE SAME SITUATION HERE IS THE SOULTION YAMAHA SENT ME TO RESET THE SYSTEM HTR-5990 YAMAHA HTR-5990 FACTORY PRESET PROCEDURES All models require the STANDBY/ON button to be turned OFF to start the reset process. NOTE: The remote control cannot be used during the reset procedure. All necessary buttons to complete the reset process are located on the front panel of the receiver. This procedure is not intended to correct intermittent shut-off symptoms or problems MODEL: HTR-5990 (U.S.A. model/s) (BEFORE YOU CONTINUE, PLEASE READ THE ABOVE NOTES!) 1. Before you start this procedure, locate the MASTER ON/OFF button and the STRAIGHT/EFFECT button on the Front Panel of the unit. 2. MAKE SURE THAT YOUR RECEIVER’S MASTER ON/OFF HAS BEEN TURNED OFF. 3. With the Right Hand, press and hold the STRAIGHT/EFFECT button. With the Left Hand, press the MASTER ON/OFF button and HOLD both buttons for no more than “3” SECONDS, AT THE SAME TIME. SP IMP. * 8 MIN. will appear on the display, which indicates you are in the Diagnostics Mode. 4. Rotate the PROGRAM KNOB to the right (ONCE) until the display reads PRESET *CANCEL. 5. Press the STRAIGHT/EFFECT button (ONCE) and the display will change to PRESET RESET. 6. Turn the unit off by pressing the MASTER ON/OFF button. 7. Wait 5 seconds, then turn the unit on by pressing the MASTER ON/OFF button. You have now reset your component to the factory settings. NOTE: Yamaha receivers don’t have to be reset during normal operation. It is not recommended that you reset the receiver unless a setting has been changed that you are not aware of, or the receiver is not operating properly. The reset procedure will clear an incorrect setting that might be causing abnormal operation. GOOD LUCK
