    Power on ... charging condensators ... after very short delay:enters with blinking LED.

    Prior to the issue; Exposed to some heavy use in a 5.1 speaker configuration, though working after this.

    B-Speakers also connected though not engaged while incident occurred.

    Schematic for this with measurepoints and reference voltages -anyone?

    I forgot why i put the receiver in the closet: its "power off" mood swings.  I've noticed that when the stand-by light is flashing, it's in one of it's moods.  Once light stops flashing, e.g. three days later, the receiver will work... for awhile.

    My Denon AVR-1600 amp simply shut off last night.  Came back on for awhile then quit again.  Power light still on.  Any ideas?  Should I fix or trash?

There is a problem with one or both of the audio amp circuits. The amp is going into a protect mode as to protect and save your speakers. Sorry but there is no simple fix. this will need to go to the shop to be diagnoised. Good Luck

I have an Onkyo TX-SR501 reciever/home theater amp. The sound works fine in home theater mode, but no sound when FM mode selected, but fine in AM mode. Have checked Antenna.

Hi Anil, please make sure the the receiver is locked into the station. It should read FM Stereo when locked in. Thank you, Onkyo USA

Keep blowing fuses.

Possible that there is a short and is much related to the power section or the output driver. You can isolate the outputs , remove the speakers and check to see the power drain current using a series clamp meter. If the current drain is high then the power section must be checked.

I got an Onkyo amp- TX-SR674, don't know why i turn on it but after 2 seconds, it will switch off and standby light is flashing, can many times. Please help

If the stand by red light starts blinking after 4 seconds of switching On it indicates an output short circuit. In all probability one of the Amplifiers output stage is defective and to prevent speaker damage the protection circuit is getting activated in 4 seconds. You will need professional help to fix this.

I have an Onkyo TX-SR507. I just hooked it up

Hello Katieandjona,

My first & second
guesses would be monitor & head-set modes...
(possibly Zone 2 activated)


To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [ON/ STANDBY] button (see page 93).

Manual... page 5

Hope this helps

Onkyo tx 906 amp

1) I bought the same Onkyo model from goodwill a couple years ago and it had the same problem. The solution is simple: Get yourself some Deoxit D5. This is a spray that will clean out all the oxidation in the volume pot. To do this you'll need to remove the cover of the receiver. Deoxit can be bought at guitar shops, or if you know a musician they might be willing to do it for you.

2) User manual is available for download, for free. Google "Onkyo tx-906 receiver manual".
