Hello,
Last night we were watching a movie and during the storms the TV and receiver shut off. I honestly do not think we lost power but seemed like there was some kind of surge. Both TV and Receiver are plugged into a surge protector. The TV came back on and the cable reset. However, the Receiver will not turn back on. It is a Yamaha AV Receiver RX-A760. If I remember I purchased it back in 2017.
Here is what I tried, but nothing has worked:
- I unplugged the power cord from the back of the Receiver for 1-hour + and once plugging back in, power still did not come on.
- I tried to do a hard reset which I have performed in the past on this unit. Pressing and holding the “Straight” button while holding the “Main Zone” button. Tried this several times and nothing. I believe this was how to to a hard reset, but if not, please let me know.
- I unplugged the Receiver from the surge protector and plugged it back in. Still nothing, but TV and others are working out of same outlet/surge protector.
There is a red light lit next to the “Main Zone” button, but that is all. It flashes, but when I try the hard reset it stays solid.
I know someone that might be able to service the receiver to see what might be wrong, but wanted to check here on any other thoughts?
Thanks,
Matt

I have looked into this further. There are service manuals on the NET. That receiver had production years 2016 to 2018. So it is passed the time that parts have to be kept.
The boards are robot surface mount construction and not serviceable. Service is via board replacement.
The power supply is unusually complex, and highly regulated. The red light would indicate a hit to the power supply board.
If power supply boards are still available it might be serviceable. However, in order to get the unit up I suspect the power supply board will need replacement, after doing that further problems may be evident.
With an event like you describe, I think attempting repair will be good money after bad.
My advice is to recycle that unit and replace.
Homes now need much better surge protection. The NEC (National Electrical Code) has had frequent updating of late. The last was November 2024.
This now requires SPD-1 surge protection at entry of electrical supply to the residence, and SPD-2 surge protection on every breaker panel.
Updating all homes to NEC 24 is strongly recommended.
I have heard from more than one electrician where they have been to homes with a total wipeout after electrical storms. Everything pretty much has circuit boards with ICs now, even LED light bulbs. Washer, dryers, stoves, fridges etc. now contain complex control boards packed with integrated circuits. Mechanical relay control is now well in the rear view mirror.
No surge protection is 100%, but with proper protection it would take a massive direct hit to get passed NEC 24. A couple of years ago I had a direct hit here in Eagan MN. It came right out of the blue. There was no major storm going on. The surge protector at entry showed red after and not green, and so had to be replaced, but it did its job.
I also have a generator and in severe electrical storms I go off grid. When we lived in a forest on Benedict Lake MN, I used to switch to the generator frequently in severe electrical storms.
So this whole issue is getting ramped up because of worsening climate with more severe storms and homes and the equipment in them becoming much more vulnerable to power surges.
