Yamaha RX-V2600 does not power up

Yamaha RX-V2600 A/V amplifier clicking relay sound but does not power up help would be much appreciated

This is one of those Yamaha recievers that uses a pulsed supply in it's standby supply circuit. There is a coupling capacitor that usually goes bad.

YAMAHA DSP-AX2600 RX-V2600 Service Manual free download, schematics, eeprom, repair info for electronics

On page 107 of the service manual you will see a diagram for a board labelled POWER (2). There is a capacitor C4 on this board. This capacitor may be bad. Replace it with an X2 rated dielectric capacitor (the original one might be an ordinary metallised polyester capacitor).

On these yamahas, C4 is a common failure, 22nF greencap that looses its capacitance.

Up and running (replaced with an X2 rated 22nF 275 volt capacitor) thank you jaycee and Tekko both very very much absolutely flawless advice
I knew it would be that standby board but never would of picked that cap as it looked pristine in appearance until of course you guys mentioned it and it measured all over the place .

Merry Christmas and a Happy new year to you both

P.S. the Aussie version has a brown 22nF 275 volt capacitor for reference not green

Kind regards Paul

Now I have flickering blue lines or an occasional green screen and no picture the GUI will not come up on screen I have done a master reset and it still will not clear the problem any further help would again be great

Having the same problem with the power staying on. Error code PS PRT 107Q. It is set to turn off at 106 so do you thing changing this cap will fix it? My C4 cap is brown and 473K.

How old is this.

473K ??

If there is a standby red light and it does not power on and you get a relay clicking sound it is most likely this cap this cap .
if you mean something else please describe more of your problem .

The unit works for like a month then shut off. Then powers on for 10 minutes and shuts off, 10 minutes then off. Works for another month and then 10 minutes like before. Doing the diagnostic test it shows the error code (ac power to high) at 107. Looking in the diagnostic menu it is set to turn off if it goes over 106. Not sure how to fix.

473k is the number stamped on the brown capacitor at (C4) on the power board.
