Question about Onkyo TX-SV636 Receiver

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.

Re: Receiver turns on and off in endless cycle

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

Speaker A button turns on receiver - Not power button

With the unit on, try a reset. If there is a small hole in the back somewhere, gently poke a toothpick in about 1/4". You should feel a soft click. If there is no reset hole, disconnect the power cord for a day or 2. If that doesn't help, you'll have to take it in for repair.

TX DS989 turns off after 3 seconds

Sorry but it does sound like an Amp failure and testing the unit for other electronic component failure will be needed

Pioneer VSX-D412 directv remote code

I also have the VSX D412 and DirectTV. My DirectTV remote controls the D412 fine, but I did have the same problem you're experiecing with a Sylvania flat screen that the remote wouldn't operate. I corrected my problem by turning the TV off, then back on using the TV's remote, then telling the DirectTV system that I didn't know the model number and let the system search for the code. Hope this helps.

I can't get the receiver button to work on my remote control. I turned it off some how? VSX-1020k

You could try this:
1. Press and hold the R.SETUP, press "4" for three seconds. The LED flashes continuously.
2. Press the number button "1"
Now press the receiver on button. Did it work?
If it doesn't try taking the batteries out of the remote and wait for at least 30 seconds then put them back in and try turning your receiver on again using the remote.

Yamaha rx-v800 turns off

Sounds like your receiver has a cold solder joint on the power board at a transistor or capacitor. Not a major repair, however, it will probably run $100 or so to pull it apart, hunt it down and fix the problem. Not sure of your problem with the DVDR. Do you have a "line conditioning, surge protection" unit? Not a Power strip or low end monster surge. Panamax, APC, Furman, make line conditioning surge units that keep your power steady and will shut down in case of voltage fluctuation in both directions. They cost from 200 to 2000 depending on the equipment you are protecting. It is a necessary component to any system. Hope this helps.

Yamaha receiver/remote mute button.

Hi brawex

Try this first... unplug amp from the wall overnight and see if it powers up the same in the morning. If the problem is still there, then unplug and leave for 10 days....I know that's a while, but what we are trying to do here is reset the unit back to defaults. One of these 2 methods will allow the working memory of the unit to be cleared, and the mute problem will go away. You WILL also loose all your station presets and surround levels settings also, a small compromise to get it working again.

Another approach is to repair the remote control...I could talk you through that also. You choose. Comment back to me here if you want to go the full method and fix the remote :)

Input selector on my Yamaha RX-V596 stuck

Hi Dush

Sounds like the processor has locked up in the unit. Try powering it right down from the wall socket for a day to reset, and then retry operation. If that does not work, leave it disconnected for about 10 days to erase backup memory completely and then try again. Good luck. Don't forget to give me a "FixYa" rating if this works. If it doesn't, get back to me in here and we can talk more about it.

Sudden failure to power up

I've had this happen a number of times with my receiver. This trick from the Troubleshooting guide in the owner's manual usually does the trick: To reset If an unusual condition in the display window or malfunction occurs, reset the unit as follows. 1 Press the POWER button to turn off the power. 2 Press the POWER button while pressing the ENTER button. Everything stored in memory after purchase is canceled. If the power cannot be turned off in step 1 because of a malfunction, reset by disconnecting the AC cord and carry out step 2.
