I had an Onkyo Receiver for a short time and I believe it fried. So I got another receiver Yamaha and IT keeeps shuting off. I unlugged all speakers and actually everything. Then it is fine. As soon as I hook an HDMI cable or a digital optical cable from the Satelite box to it, thats when it starts to shut down again. I CANNOT figure for the life of me what is going on. This started with my Onkyo, but still persists with the Yamaha. I even swapped the sat. receiver. Chaned plug outlets. What could possibly cause this. Appreciate any help in figuring this out. Thanks, Al

Re: Home Theater Receiver keeps Shutting Down
Have you tried a different input on your TV? HDMI communicates both ways. You could have an issue with the input port on the TV. Try using Component. If you still have issues post a reply and we can dig further into it. Hope this helps

HI Bart, which model is it that you are using? Have you tried a hard reset? Please email me the units model number so that I can email you the reset procedure for your model. You can email me at [email protected], Thanks, JT
The receiver doesn't have a password, but the unit can be fried, let's go with by a process of elimination.
First, the most noticeable procedure would be to not plug in anything in back of the receiver, and plug it in the an outlet and turn it on. If the unit shuts off after a few seconds, then the unit has a short and must be sent in for repair.
If the unit stays on, then there is something that is being plugged into the Receiver that doesn't seem to agree. Start by plugging in one source at a time and repeating the step above. It's a slow process but hopefully and eventually, you will find the culprit.
In most cases though, it usually the speakers wires in the back touching even a slight bit or your speakers impedance don't match what the receiver is capable of taking.
I strongly recommend starting with the first step since this will allow you to figure out if the receiver is defective or is something else the culprit.
Hope this helps, Best of Luck
What leads you to think you fried the power supply in your unit? While touching the speaker wire to the chassis is never a good thing it should not have fried the power supply. Might have opened a fuse in the speaker circuit. Have you checked all the fuses yet? Try that first and get back to me and make sure the unit is unplugged before you open it up!!!
Check all your connections.. The best way to troubleshoot this is, unlug all your speaker and a/v connections. Just leave power plugged in. If it still does it? It could be an internal problem. If it stays on after? Attach your connections one by one until you see which one is causing the short.
the reason why the receiver probably keep turning off is that the systems come with overload protector to keep one from burning or short the systems out so it shut its self off. make sure you have the speaker wires is connected properly, its very important that you do although the receiver has 0% tolerance when it come to speakers hook up. positive from speaker to positive connector behind reciever; same as negative. double check all speakers wires. repost if that not an issue
Onkyo & Harmon Kardon it a very nice unit and it built very professionaly and very sensitve unit. Its very important that you make sure the correct pole is connect correctly when it come to speakers. the unit come with resetable breakers inside the receiver (safety protection) so you wont blow or short the unit if not connected up correctly. when wiring speakers up from an to the receiver you have to make sure the poles are hook up correctly. positve speaker wire go straight to positive plug behind the receiver same as negative. the speaker wires should have some kind of making on it to mark as either positive or negative. try that and see if that help, if nedd more help.
Onkyo directed me to return the unit to a service center. Apparently this is a known issue and after reading web postings I believe it. There were dozens of similar cases with a variety of Onkyo recievers. I was able to remove the ribon connector from the headphones and discovered it is not a shorted headphone detector. We will see what the service center does. I'm not looking forward to paying for shipping a 66 lb receiver.
No, they are brand and model specific. If you visit a local retailer that sells Yamaha, tell them your model # and they may even have a mic you can use. If not, let me know, I'm a Yamaha dealer and can get it for you or point you in the right direction to get it. Hope this helps
If the receiver shuts down after some time operating properly it is likely caused by a heat issue or crossed (shorted) speaker wires. Please make sure that the unit is adequately vented and the air vents/fan on the back of the receiver is clean. If it is then carefully check all of the speaker wires for cracks, damage, and/or crossed wires.
check to see if there are any speaker wires that are touching each other near the connections. i had this happen on an onkyo receiver and found it was a purposeful feature intended to keep you from shorting out the receiver. if the + and - speaker wires touch (at the receiver posts or the speaker posts) this can happen.
