Onkyo TX-SR502 AV receiver

When powered up there is no sound at all. It receives a signal , but has no output. It is three or four years old and has had only medium use. I have a TX-SR602 and the same thing happened this morning. Working fine last night. Could only find 4 fuses but all were good and power related. Everything works on unit except sound output.

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

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.

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 Subwoofer Pre Out Problem


May not necessarily be the out put, discontect the sub from the receiver and see if it still makes a hum, Making sure that you turn auto on, off on the sub woffer.
If it still makes a hum, then you have a earthing problem, you can get a earth filter put on your internal wiring in your home, or you can remove the earth pin on your sub woffer
