My yamaha rx-v461 won't turn on

take it in for repair as the power surge has damaged the electronics on a board
quality surge protectors are the preventative equipment to be used for ALL equipment running electronic controls ( includes fridges and stoves,and air conditioners that plug in

Surge associated with power outage can make disasters in refrigerators. You need a power protector for refrigerators.
Now, what already is damaged, should be repaired by an authorized techician.
For protector, you can do a search; typical return is this one


Electronic Surge Protector for Refrigerators up to 27 Cuft and Freezers

If you have any electronics experience you should check the diodes or the bridge rectifier in the power circuit. Look for burned components or bulged capacitors.!!!Always unplug the unit and wait a few minutes before attempting any procedure!! I have found that capacitors usually fail due to voltage spikes which can happen when power is reinstated after an outage. Always use surge protectors on electronic devices. They have a component called an MOV that will absorb voltage spikes and save your equipment.

The protection mode has activated.
Reset the protection mode as follows and see what happens.

Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.

It has many, depending on the your speaker configuration, the source hardware and the source material...

Hi,
Here you can find the manual for your subwoofer. Looking at its back side, it has 2 RCA plug input for stereo. Receiver has just mono sub output, but as low frequencies are not easily locatable, mono is perfectly OK.
Just connect receiver SUB-OUTPUT with RCA cable to your subwoofer's RCA LEFT input. Then adjust volume to match rest of your speakers.

Sounds like your power supply may be shot on your computer. You can get a power supply tester and check it. Not sure what to do about the printer. If you had a surge protector in between your computer and ac. Plug the computer and printer back in to the AC outlet directly and see if that helps. Hopefully only your surge protector is damaged.

Please rate, Thanks.

you have a faulty circuit somewhere, whether its in speaker wiring, or power source, i dont know, but your reciever has an automatic circuit breaker in it for protection, and a faulty circuit will trip it, i would assume it is a power source problem since it wont turn back on, check wiring, plugs and look around, and smell for burnt, or hot components.

LOT OF TIME WHEN YOU LEAVE IT OFF FOR THE NIGHT DISCONNECT POWER CORD DEFECTIVE SURGE PROTECTOR IS NOT GOOD FORE EVER PLUG TV IN THE WALL WITOUT THE SURGE PROTECTOR IF IT GOOD CHANGE THE SURGE PROTECTOR FOR NEW ONE CHEERS
