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.
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.
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
