Question about Onkyo TX-NR609

Open Question

My onkyo receiver (TX-NR609) cpu needs to be replaced

According to my technician, my onkyo receiver had this voltage fluctuation, which sorted the cpu. It seems a small transfer was also malfunctioning, which I already got fixed. But the cpu has been sorted too and that needs to be replaced. Whenever I connect onkyo to power, the main screen goes on and then standby more alternately and continously, till I press the standby mode. Then it goes to standby mode. If I press any other key after that, same thing starts repeating! Even after fixing the small transformer, I am facing the same issue. Technician seems to be convinced that it is sorted cpu, since it is not passing 12v output! Now I don't know from where to buy this cpu. Any idea? I am not even sure whether replacing that will take care of the issue. Anyone faced similar problem?

SOURCE: no sound from the receiver

Loose connection or cold solder and cleaning problem this is the main caused of no sound..Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....

Good luck:

SOURCE: Onkio receiver

The output transistors should be replaced in pairs. Also, It may not be just the output transistors that are defective. If you have no experience with these types of repairs, I would suggest that you bring the unit to a service shop. The outputs will run about $15-$25 per pair.

SOURCE: Onkyo TX-SV919THX, No Output

I have found the battery location. It is roughly on the opposite side of the pc board where the display is. It basically faces the heat sinks. It's one of those small watch sized batteries and is soldered but sticking off the pc board with 2 leads. I could see that there was some leakage and corrosion. I still have to figure out what needs to be dis-assembled to get access to it so I can unsolder the bad battery and replace it. This stupid little battery seems to need replacing every 6-8 years! When it dies, it seems to disable the preamp section from passing any signal giving the symptoms that the amps are dead. However, if you try to use the pre-outs to an external amp, nothing. So, my guess is it has something to do with the preamp section. Anyway, that will be my weekend project to try to get at the battery and replace it with "longer leads" so it will be easier to replace in 6 years when it dies again. Great design Onkyo! You dumb-*** weasels!!!! I hate when companies engineer things to break so you are likely to pay them to fix it. Not this time, "No soup for you!"

I'm using an onkyo tx-nr609, I have a wireless speaker adaptor plugged into zone 2 on the back next to where the subwoofer plugs in, but can't seem to get any sound to come out of it. Any ideas?


Hi Chris, not all sources will play to zone 2. Only internal and analog sources. If you want to play your cable box for example you need an analog connection from the cable box to the receiver. Also, the output is very low it needs to be amplified. Thank you, Onkyo USA

My Onkyo TX NR609 is not coming on and immediately shuts off and is progressively getting worse it is hooked to a harmony smart hub


Hi Liz, I am sorry about your issue. Please remove the HDMI cable from the receiver that is connected to the TV as a test. Check and see if the receiver stays on. If it does not the receiver would need to be serviced. Thank you, Onkyo USA

The server connection could not be established or was terminated early. PLease try again later. Trying to play Pandora on TX-NR609


You didn't say if you were using their wireless "dongle" or an ethernet connection. If ethernet try to connect another device - laptop, blu-ray or etc to see if you're getting a good modem signal. You might try re-setting the ethernet connection on your 609.

I'm assuming your audio is working, Onkyo had a lot of trouble with their HDMI cards, for some reason the defect usually took out the audio and ability to connect to the web.

Onkyo had a recall on 609s and they will repair the defect, free of charge or shipping. (In a range of serial numbers that, unfortunately, I do not know.) I took mine to a local repair shop and they told me it was recalled. It was about a year out of warranty but they fixed it.

How do I get network audio


You need to buy a network adapter for your receiver. Onkyo probably sells one.

No sound from receiver to speakers


It's been several months since the original post but :

The HDMI board on several different models of Onkyo receivers were defective. There was a recall on these receivers and Onkyo might fix them for free, even if the receiver is out of warranty.

Cant get tv audio through receiver directly (without satallite, Game, DVD connection)


If your TV doesn't support audio return channel (ARC, which is your TV audio routed back to the receiver through the same HDMI cable), you then need to connect your television audio-out to your Onkyo TV audio input, using a digital cable or an analog one according to the connections on the back of your TV. If you use a digital connection (optical or coaxial), make sure you have the proper digital port assigned to TV on the onkyo I/O assign menu/digital inputs.
In case your TV does support ARC, you need to activate it in the Onkyo's hardware/HDMI setup menu, either by turning on HDMI control (tv or receiver control each other via cable), or by turning ARC on (you'd probably need to activate ARC on your TV as well).
Hope this help,

Receiver will not turn on and is making a clicking sound TX-NR 609


This is the same problem i've had with my POS nr609. I will never buy Onkyo again.. Everyone warned me about the poor quality.. This thing worked for a year and a half, blew the amp., replaced and now another year and a half, f'd again. Save your time, buy a Denon or a Harmon Kardon. Better quality, same features..
