Yamaha HTR-3064 A/V Receiver. It suddenly stopped responding to the remote?

Sounds like you have degraded, failing capacitors. Take it in for service.

Unhook the speakers and see if it does that. If it does then one or more speakers are bad. If that does not help a sensor circuit is bad or a driving transistor is bad

According to this troubleshooting guide from your OM, it has some sort of "3-tries and then dies" circuitry that MAKES you take it to Yamaha service for repair/reset. Sounds like our auto\'s and the "check engine" resets...geez!

I had a Power surge in Brisbane this week and found my YAMAHA HTR-3064 AV receiver unresponsive. Thanks to the Squish22's post, I tried the above approach, which is also listed for another Yamaha model (RX-V667) Unfortunately nothing happened. Another post suggested holding the 'straight' button as you power up to go into "advanced" menu (under DILLIGAF's post.) This also did not work.
I thought I'd try pressing all 3 buttons and powering up, which worked a treat. so here's exactly what I did:

Yamaha HTR-3064 - Protection mode reset:

1. Remove the Power cord form mains power and wait 10 seconds.
2. Plug cord in and turn on wall socket power.
3. While holding down "info", "straight" and "tone control" buttons, press "main zone" power button. I got a click and it was good to go from there.

I had all of my speakers unplugged at the time and tested off the headphone jack before plugging all the cables back in again. Not sure if I needed to unplug everything, but I was about to dismantle and look for a fuse when I tried this method.
Saved me a new system / service fee. Hope it helps you too.
Thanks Squish22 and DILLIGAF for the head-start!

Dear sir my name prakash my won us Yamaha AV Receivers Model RX-V673 Go To died mode what this problem please sir?

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.

You can find the manual here...
