Question about Onkyo TX-SR803 Receiver

1 Answer

Listening modes not working??

I have a Onkyo Tx sr804 and it is used very lightly. Just the other day the listening modes stopped working for my sources. The only listening modes that sound comes out are the "direct" and "pure audio" listening modes. All other listening modes show up and I can change them, but there is no sound at all. This sucks, I've only had the receiver for two years. Talked to tech support they gave me all the usuals, reset, unplug. Did all that, didn't work. Any help is appreciated before i have to send it out for expensive repair.

    Thank you very much for your quick and great reply. So I'm guessing my next bet would be to take it to the authorized onkyo tech nearest to me. What can cause these problems to happen?? Do you see this pften??

    Once again I appreciate your time and sharing of knowledge. If I have any more questions I know where to turn. I'll just ship it to you, ha ha ha!!

    Thanks again!!

    Hey Dave, sorry to bother you again for your input, but why are those two "listening modes" still working and not the others? Is it just the pathways and the way they are set up? And since those two still work is that a clue as to there not being multiple unfixable damage to the board??

    Thanks a ton,

I am a little hesitant to tell you what this is because sometimes people give bad ratings to an expert when they do not get the answer they want to hear. I will take a chance here and assume you are a reasonable person and tell you what the most likely cause is. I have been reparing these type of receivers for as long as they have been making them, and every time I see this particular problem it is always something on the digital board. This is the board the the optical and coax inputs go into on the back. They also run all the audio thru this board, and when you only get the audio that you have, a problem is going to be found there. There is some good news and some bad news that goes with this, first the good news. Many times (about half), the digital board only needs to have some of the solder reflowed on a few of the IC's and it will return to normal operation. If this is the problem your repair should only cost from $90 to $150 depending on the rates of the shop. Now the bad news, if the board has a couple of bad compnents on it, it will need to be replaced. The reason that is bad news, is because those boards are very expensive, usually over $250 just for the board, if the board is even available. Many of these receivers you can not get the digital board for them. Most all of audio equipment is component level repair and there are not many technicians who can troubleshoot these boards, they are a very difficult task.

I hope this free information was helpful, and if so a "FixYa!" would be the appropriate rating. You do not need to have your receiver fixed in order to give a good rating, only that you are given the correct information.

Let me know if I can be of any more help to you, good luck with your Onkyo.

    I see this type of thing a lot. The most common reason is because of the heat that audio receivers generate. It causes the solder to get degraded from the cycle of heating and cooling over and over again for a few years. It just breaks down the chemical composition of the solder. The solder will still hold, but it just doesn't have the right properties anymore to conduct electricity they way it needs to for these circuits to operate at proper levels. It can even cause the components to break down from heating and cooling in cycles and with bad solder connections the components do not have the proper voltage levels either and that can cause component failures.

    And yes, an authorized Onkyo service center would be best, but if it is not under warranty you can take it to any good service center.

    Thanks for the great rating, I really do appreciate it. It is the only reward we get for offering people free help. You would be surprised at how many people give bad ratings because the answer they hope for is not the correct answer. Some experts even give wrong advise because they think it will get them a better rating, I won't do that, I will live the results of the truth.

    Thanks again,

    When you start getting problems with these digital boards the problems can be very strange and not make much sense sometimes. Thats one of the reasons they are so difficult to troubleshoot as well. I have actually fixed some of these thinking that the part I am replacing is not going to fix the problem, but it does fix it, or sometimes it will only fix part of a problem. When you have several problems and trace it back to a particular part, but that part only fixes one out of 2 or 3 problems. Sometimes there just seems to be no rhyme or reason to why some of these problems occur or what it takes to fix them. Bad solder connections seem to be a very big problem with audio equipment because of the heat they generate.

I have an Onkyo TX-SR804, it's stuck on CD mode and the volume is stuck on -22. It won't let me do anything, to turn it off, I have to unplug it. Before it got "stuck" it would scroll thru modes.

Your electronics have gone south and unplugging unit will not reset them . So, it is a trip to the repair shop. Get an estimate first because if it is too expensive might just be better to replace than repair.

The Mainboard on the TX SR804 is falty and i just fixed two units with this solution and it bullet prof un der the HDMI board you will find the mainboard stating up right with its back facing the preamp board and it has 3 screws that secure the mainboard to the system 2 on the middle top of the receiver and one on the right side just under the screw you removed for the HDMI board that secures it to the Audio processor board.
Once the screws have been removed pry the board back going from left to right and slowly disconecting the board. THE FIX. once infront of you clean all of the ribom connectors and the and bend the pins on the connector P954A, P959A , P2005A and P2004A THESE CONECTORS ARE THE REASON THE SYSTEM WILL SHUT DOWN SPECIALY THE FIRST TWO. I ALSO RECOMEND PUTING A INTERNAL FAN POINTING TO THIS BOARDS KEED THE HEAT DOWN. the reason the SUB is low or the HDMI does not seem to work well they are related to the SIF connectors on the the are 4 on this board and i used a thin bud hard plastic and inserted bering each sif cable to push the pins againt it. this is a 20 minute job and you amp will be fixed. i fixed many like this. Have a wonderfull holiday. Mvianna

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.

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.

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.
