Yamaha R-V905 Receiver Questions & Answers
1 Answer
Will not turn on.
It has an internal problem. Just received an RX-V2600 back from service for the same issue. It took a voltage drop then a spike. It takes out 5 caps and a few other parts. The repair will run roughly 250-275 depending on who does the service. Hope this helps

Yamaha R-V905 constantly turns itself off
Two things I think are happening. It is overheating and it has suffered some sort of damage to a component inside. Try to make sure there is ventilation on all sides. Can you remember a time where you did not have adequate ventilation for this device? If so maybe that is what caused the part inside to fail.
Hope this helps
Thanks for reading!

How to reset yamaha R-N402 power protection circuit
Remove the short that is causing the protection to engage, then power cycle, assuming it's a short circuit protection. If it's going in to thermal protection, then shut the receiver off and let it cool. If all speaker wires are disconnected and the unit is cool to the touch but still appears to be in protection mode, likely one of the output transistors has failed an will need to be diagnosed and replaced. Don't neglect to check the ESR of the electrolytic capacitors if you find a failed device internally.

I have yamaha ex395 turn on for 3 second ten turn off how to fix
Unplug all your speakers and components. Then turn on, if it still locks up you have one of maybe 5 safety features hooked up that are built in to stop your amp from blowing. You will need to replace board or have some cool tech dude desolder and isolate . Look for wiring diagram for safety shut down system. Sorry but if it doesn't do it after you disconnect every thing then check each speaker with ohm meter to read factory specs.

Yamaha Rx-V371 will not turn on
It's in protection mode. Disconnect all speakers and hold the Tone and Straight buttons while hitting the power button. Hold all buttons down for 3 to 5 seconds. This will turn off protection mode. Now power down then back on. If you haven't damaged anything it should work fine. Make sure all speaker connections are good. Always power down the unit before making any speaker or other connections.
