Question about Onkyo TX-SR801 7.1 Channels Receiver

Open Question

I have an Onkyo tx-sr804 receiver. It's connected to a Mits. WD-52631 DPL TV. When i turn the system on to watch TV, my picture flashes for the first 10 minutes or so until it gets warmed up. I suspect it's the Receiver not the TV that is the problem, because if I turn on the radio only prior to turning on the TV, it seems to allow the receiver to warm up and the TV picture will not flash. Any suggestions? Thanks

SOURCE: Onkyo TX-SR804 power supply

If you imply an AC voltage transformer by saying "power supply", I don't believe it will be difficult to find one. If you stay in Istanbul, I recommend that you go to "Dogubank". You can choose from a wide variety of options at that place. All you have to pay attention is that the AC frequency (Hz) of the transformer you're about to purchase. It must be around 50Hz to operate your amp.

Hi there, sounds like you have a ground loop happening there. Check out ground loops in google to get some tips. What you should try is use one wall plug for everything (with an adapter on it) and check that none of your other cables are damaged. try find new cables and put them in place of the old seemingly fine cables.

SOURCE: onkyo tx sr804 receiver turns on by itself

I have the same receiver and the way to fix is simple. in the main board of this unit there are 5 connectors and they slide into other components like Lego. the issue is the king of material they are made of it's cheap. if you reseat the mainboard it will fix it for a day or two, them it will start again. the easyway is to re seat the board and put a fan inside of the receiver between the transformer and the inside of the amp pointing down about 20 degrees connect the fan to a ajustible voltage adapter and connect it to the outlet in the back of the unit. so it comes on when you turn it on. this voltage adapter is cheap. the adapters people buy for phones and or MP3's at Radio shack or Best buy it goes from 1.5v to 12 volts/ this way you can control how loud the fan is in side the receiver. i find 4.5V does the trick. The connectors on this board start to loose contact with some of the pins when heated. the fan keeps it cool enouth to fix the issue. I fixed manny these ONKYO 804's this will fix it. you just have to do it. the main board is inder the HDMI board in a Vertical position running from one side to almost the Power supply. it has 2 screws also holding it in the inside middle back of the amp. Becarefull with these amps 75 V at 23amp's DC is no joje leave it off for a couple of hours to satart working on it. Good luck.

I hooked up our Onkyo TX-SR607 system a few weeks ago and have watched several movies, but now I cannot get the Hitahci PH35811 TV to sync up to get video. I get audio, but no picture when we try to watch...


Are you routing the video into your reciver from the dvd player? If so route the video directly into your tv. It won't fix the initial problem but you will get picture and sound to watch dvd movies.

No sound in listening modes except pure audio and direct. Was working fine and just stopped one day. Connections are all good. Surround sound seems to be broken?


Check the input mode on the reciever so that they are set for dual, rather than just digital or analog. It might be set for analog and your using a digital optical in cable. Also make sure DTS mode is turned off, unless your watching a DVD that is dts enabled.

The receiver thinks there are headphones connected


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.

Check the rated impedance of your speakers. Use the manufacturer's rating. Don't try to measure it with an ohmmeter. This should be printed on the rear panel. If not, check your manual if you have one. The receiver probably shouldn't be connected to speakers rated any lower than 6 Ohms. If the speakers are 6 or higher, check your wires and connections for any stray strands that could be causing a short. I also have to wonder what "increase the volume substantially" means. Are we talking potential hearing damage? Maybe the receiver is saving you from your self.
