Onkyo TX-SR502 - o Sound!

After enjoying this receiver for 2.5 years, it has decided to not output sound any more. Are there any solutions to this problem other than purchasing a new system? By the way, I get no sound from speakers or headphones. Also, no Test Tones sound either. Thanks!

    I no longer have output on any of my speakers after 3+ years of great performance. I purchased the service manual and ran the DSP diagnostic which causes the display of the following code: _1A48E710x_00_x. Most of it makes sense for the auto FM tuning mode the receiver is in, but a 7 in the 7th field is not even a valid state (only 0,2 or 5 are valid) and the last x indicates that the DSP is NG. I could replace the DSP chip or board but the invalid code makes me think there could be other problems.

    Same problem -- no sound. Yesterday, my TX-SR052 worked perfectly. Today, nothing -- all panels light up as if nothing's wrong, but no sound from speakers or headphones.


    Duncan's solution sounds great, and I'd love to investigate further before scrapping the unit and buying a new one. Problem is, I don't know how to test/remedy this (DC voltage problem). Please advise.

    I have somewhat of a similar solution. After 3+ years of no problems, yesterday afternoon I turn on my receiver and no sound. Everything looks fine on the display. Then about after 5 minutes the sound comes on and works beautifully. This has happened 3 times so far in a row. I just came home from work and no sound. Wait about 5 minutes, and it comes on. Would this still be a "protect mode" type situation?

    sometimes no sound comes out of any outputs

    the test tone does not produce a sound for that channel the speaker is not the problem

It sounds like your system has gone into protect mode which means you probably have some DC voltages in your output circuit area that have triggered the protect circuit. This mostly happens when you have some damaged output transistors or when they are getting some incorrect voltages themselves. When it goes into protect because of ONE bad channel then it will disconnect ALL output channels from their speakers. There are a number of things that can cause the "no sound all channels" problem, but the most common is what I have just said. I hope this helps. (I am of course assuming that the unit will actualy turn on and that speakers are attached etc., etc.) Good luck.

I'm trying to connect my old onkyo tx-sr502 receiver to my panasonic smart tv and my xbox 360 to get surround sound. Any help would be appreciated


Hello, Since the TX-SR502 does not have HDMI inputs you need to connect the HDMI from the XBox 360 to the TV. You can connect an optical cable from the XBox to the receiver if the XBox has an optical output. If not you can connect the optical out from the TV to the receiver. Connect to the optical #2 port on the receiver and press the video 2 button. You should have audio. Thank you, Onkyo USA

Can you use an Onkyo RC-771M remote control to operate Onkyo receiver TX-SR502 ?


Unfortunately, the RC-771M remote doesn't control the TX-SR502. It will only work with these Onkyo models: TX-NR1008 and TX-NR808. The RC-567M is the one for the TX-SR502; replacement remotes that are exact replacements are still available from various places including Amazon.com .

Since the TX-SR502 was released in ~2004, that replacement remote probably won't control other devices that were released in 2004 or later. Onkyo changed its IR code programming before the TX-NR1008 was released in ~2010 and the RC-771M can't communicate with the older receiver. The manuals for the receivers listed above are still available from Onkyo on the product page under the Downloads tab.

I wish that I had better news for you.

When connecting optical inputs there is no audio output


You have to assign each digital input.

Register and download the manual for free at retrevo.com

Search the document for "assign".

I have an audio problem with my TX-SR502.


If your remote also controls the Cable Box you might want to look at its audio settings. Maybe you muted it.

BTW: it would be a good idea to also run video and analog audio from the cable box directly to the TV if it has speakers so you can watch and listen independent of the Onkyo.

My Onkyo TX-SR502 suddenly no sound output. Why?


Same issue on a friend's receiver. I have checked and no signals from preamp pcb to main amp board, which is idling just fine, all channels. The day he brought in we checked it and it played just fine. I then took apart the faceplate to clean the display window and after that had it working for a day and a half while working on other stuff. He comes back a month later to pick up and now nothing. I have decided this is not going to go any further and just thought I'd share my findings. I think it's time we all move on.

My Onkyo tx sr502 quit producing sound?


I have the same problem.It's definitely the pre-amplifier board (board with speaker terminals).I did not quite nail the exact component yet but I replaced with a working one and got back sound output.

Onkyo TX-SR502 AV receiver


this could be the pre amp transistor or the power amp that needs replacing
the pre amp transistor is cheap but the power amp is not
if you did not crank it , then it is probably just the transistor that needs replacing
