Question about Yamaha RX-V650 Receiver

3 Answers

Yamaha RX-V650 receiver won't power on.

I have a Yamaha RX-V650 receiver that has developed a fault.

If you switch it to standby for any length of time, ie overnight, it won't then power back on again.
I have discovered that if you pull the mains plug out of the socket and then plug it back in again, something clicks within the amp, and you can then power it on.

This has been going on for about a week, but the other night it seemed to be worse. It took several goes of unplugging, replugging before it came on.
Once on it works perfectly well.

From my brief description could anyone hazard a guess as to what's going on?

I have searched the web in vain for a service manual hoping that might give me a clue. If it's something like a failing component then I'm sure i would be capable of replacing it.

Any pointers greatly appreciated.

In my case ButtFuzz was right... except that there was no visible faults at all....

I've fixed my RX-V650 with these symptoms by replacing the capacitor namned C405 close to the transformer with a new polypropylene capacitor of 0,022µF 630V...

Might be worth a try before tossing it out... :)

You've probably already tried this, but...

Disconnect power from the mains, remove lid.

Reseat all the low-power connectors in the unit.

Check the thermister on/near the main transformer.

Check capacitors on or near power supply for obvious anomalies (fattness, leaking, smoked, etc.)

Replace lid and, plug back in, do a rain dance and hope.

Yamaha rx-v650 wont come out of standby, fuses ok switchmode ok no display at all fault pointing towards microprocessor problem.

There is a common psu problem occurring on a few Yamaha models from ~4 yrs ago. Any Yamaha dealer should know what it needs. probably the mod component in the stby supply.

Doubt it would be a micro fault.

The unit does not work

check the standby power supply first and then the main power supply.also check the output transistors and fuses your problem is in one of those points, normally the standby transformer goes bad, it is the small one right next to the big one.
good luck

Yamaha RX-V995 receiver turns on & then powers off 2 seconds late

I suggest you run self diag.  press [FM/AM] key + [Input mode] key and press the [power/standby] switch.

ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink

you'll likely have to measure the resistances of the output FETs to find a short,

Yamaha RX-V595A tuns off automatically

This was happening to mine also, all of a sudden. This solution came from the owners manual. Sure enough, the impedance selector was stuck in the middle , between 4 and 8 ohms....I also, made sure the speaker wires were not touching each other at the splice. Problem fixed.

The unit fails to turn on when 
STANDBY/ON is pressed, or set in 
the standby mode suddenly soon 
after the power has been turned on. 
The power cord is not plugged in or the 
plug is not completely inserted. 
on the rear panel is not fully set to the 
upper or lower end. 
Firmly plug in the power cord. 
Set the switch fully to the upper or 
lower end when the unit is in the 
standby mode.
