Buttons on front panel of Yamaha HTR 5930 have become non-functional. Service ctr recommends replacement of switches. Is there any other way out? Say cleaning the switches with spirit?

Check for problem in fuel system - bad fuel - filter - carb/throttle body etc

Hi Anonymous, for what you say you may have a problem with the remote control, that the Speakers A and B keys are emitting and generating the fault, remove the remote control and check if the fault continues, if so, try resetting the team
I pass you the link to download the user manual, look at page 65, the procedure for the reset
I hope you can solve it
Greetings Franco Dosil

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,.

Yah, I know :) An answer to a 10 year old post probably isn't going to help the OP but this was the only thing I found anywhere that matched the exact issue that I was having with my HTR-5930 receiver and RAV309 remote, the remote was confirmed working but no response from the receiver. I checked the output of the IR receiver diode behind the display panel and it did not respond to remote signals so I found one on Amazon (ELEDIY 20Pcs IR Receiver Diode VS1838B - 38KHZ) and replaced the original one and everything works again.

I cut the original leads off 1/4-3/8" above the board and took the old one out of the case that remained soldered to the board (you can bend/swing the bottom 1/2 of the case down and slide the diode out towards the leads). The shape of the lense on the replacement diode was a 1/2 cylinder rather than the original 1/2 sphere so I had to cut a slot in the face of the old case from the bottom up to the opening to make room for that, I used a dremel cut-off wheel. Once you get it fitting in there, bend the legs of the new one and trim to length so they overlap the stubs you left from the old. After bending/swinging the bottom of the case back up the diode is nicely held in place and you can finish lining up the old and new legs, solder them together, test things and then reassemble and enjoy your receiver working with the remote again.

The XBox is probably hooked up separately to the amplifier, try cycling the inputs on the amplifier. If that doesn't work replace the cbale between your amplifier and tv.

... Incorrect setup; incorrect speaker definition; speaker B selected instead of speaker A.

makesure the ampis set on dolby prologic 3 channel

On , HTR-5930, composite inputs are routed only to composite outputs. The same happens to component input. You can't see video from V AUX if your TV is hooked-up on component output. Also, check if you connected correctly GREEN, BLUE AND RED on both receiver and TV SET.
