I have an Onkyo TX-DS575 Onkyo reciever. I cannnot operate the reciever with the remote. All the buttons on the panel of the reciever work fine. I have programed my DVD player remote into the DVD mode of the onkyo remote and that works the DVD player fine. When I switch the remote back to the Audio mode it doens't operate the the Onkyo reciever. This tells me the remote has enough power to send a signal. I changed the batteries just to make sure, it didn't make any difference.
I had the same issue and solved it by replacing the IR receiver on the front panel with a Rohm RPM7138-H4R which I ordered from digikey (RPM7138-H4R-ND).
Hello Fixya customer,
Thank you for your question.
Please determine if the "Audio" button is actually working.... after pressing the audio button, can you still control the DVD, if not then the remote has switched to the Onkyo. Although, this is not 100% conclusive, unless you have a 2nd remote to test the Onkyo with, it provides a sound basis to proceed.
Assuming the remote is transmitting and the IR receiver on the front of the Onkyo is not otherwise blocked, likely faults include the IR receiver, input to the Micro processor, and the Micro processor.
The most probable fault is the IR receiver.
Thank you for using Fixya, and if I can help you further, please let me know.

Normally you hear a clicking sound coming from the inside when you turn on your amp. That's the sound of the magnetic circuit breaker (switch). If you tap your amp to turn it on, and if the amp gets turned on after you did it:), then I suppose the problem is on the relevant switch.
