Onkyo tx-ds575 receiver shuts down when switching input and sound functions.works fine otherwise

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.

Most likely is that you have weak capacitors in the power supply,if your not a tech. i`d rather not be more specific.

Check the units internal "menu" settings for speakers and audio. beyond that, there would be an internal problem and neded service. Hope this helps

You have a problem that was inherent with all Onkyo receivers from this period. You need to contact Onkyo because the microprocessor needs to be replaced. Last I checked, its about $80 from onkyo.

This is NOT an isolated incident as darn near every Onkyo receiver model had this problem.

Good luck...

You have to raplace IR sensor PIC-26043TE2 or similar and should help.

I would check your wireing in the system end and just make sure nothing has loosened up over time this can happen even if you don't move the system. The only other thing I can think it maybe is the system is overheating and shutting down. When it does it again carefully feel around the system particularly the rear of the system if it is really hot it is probably shutting down. Is the cooling fan runnig?

Had it ever worked, or are you setting it up for the first time?
Have you ASSIGNED the digital input in the menu?

Hi, I just started having the same problems with my Onkyo TX-DS575. I have to play with the DSP buttons...the A/B speaker button...and now it has gotten to the point where my family and I lift the receiver up in the front, and slam it back down on the shelf and then hit the DSP buttons again and eventually we get some sound. This unit was already fixed once by Onkyo right after the 2 year warranty ran out for a similar problem. They returned it working...but scratched. This is the second Onkyo receiver that has died an early death within 15 years. I love Onkyo's styling, ease of use and sound, but I found the best way to solve this was by purchasing the Yamaha RX-V861 this week. I am done with Onkyo. Scotty D, Middletown, NJ

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.

Called Onkyo and here is the solution they gave me.

1. Turn on unit.

2. Press and hold VIDEO 1 button.

3. While pressing VIDEO 1, press Speaker A button.

4. You should see "CLEAR" on the display for a second and it will go on stand-by mode.

5. Turn on the unit and check if sound is back.

Hope this helps
