Question about Onkyo TX-SV636 Receiver

1 Answer

Receiver turns on and off in endless cycle

The receiver has operated flawlessly for years. Two days ago, I turned my receiver on via the power button on the remote. It came on, and then sut off a half second later. It continually tries to turn itself back on, then shuts off one half second later. This is an endless cycle, and the only thing that I can do to make it stop is to unplug it. Upon plugging it back in, it immediately enters this cycle again, without me trying to turn it back on. If left unplugged for a good while, the on/off cycle will start slow, but then will quickly get back to its regular pace. I took the cover off, and the main fuse (6.3A) looks fine. I unplugged the speakers in case there was a short, and that did not alleviate the problem. With nothing plugged into the receiver, it still does this. I'd appreciate the board's expertise in solving this.

Its one of Three problems. The main b+ filter is defective, one of the standby power sources have a bad capacitor on the line, or theres a short in the main amp. section. Its probabvly going to cost you more then you would care to invest in a reciver thats around 5 to 6 years old. Its most likly time for you to upgrade to a suround sound dydtem with new fancy lights bells and whistles. Good Luck

When I turn the receiver on, it suddenly turns off after only 4-seconds. Advice?


sounds like there is a problem in the amp. If you hold the "STRAIGHT" and "AUDIO SELECT" buttons and then press power, what does it say on the display? This will help narrow down where your problem may be.

press and hold both the "DIRECT" and "TONE CONTROL" buttons and press power and see what it says on the display. This will give us some idea of what is causing the receiver to turn off.

Why would JVC 8010 optic digital randomly malfunction?


I don't know if this helps but, if you have your bluray hooked directly to your tv some times TVs can have issues sending the proper channel to audio out to the receiver. You should always connect your bluray and other devices directly to your receiver.

if that's not the case,
Try turning the tv speakers back on, test the bluray hooked directly to the tv and see if things work flawlessly just with the tv and bluray.

If they don't there may be something just wrong with the cables.

If they do work flawlessly then there may be something wrong with the receiver.

If you already had your bluray connected to the receiver, I would still try direct to tv test and swapping cables.

The randomness leads me to think cables. But you can rule them out by testing directly to TV.

I hope that helps

My DVR-625, wont even turn on.


at the time the hard drive problem came up the receiver would of went into recovery mode this can take a good hour for it to fix and can do nothing until it would finish on its own and take care of. Doing the power reset is just like unpluging the receiver. Try unpluging again for 30 minutes and plug back in again and just wait receiver should come back on its own. Don't hit any buttons. If not will have to send out to dish for repair. 800-333-3474 dish
