SOURCE: my onkyo tx ds747 is saying protect even if i dont

Hello

maybe you have defective power transistor output and this is shorted, or the problem is in the power section like shorted diode shorted capacitors or open circuit may cause this, and the STK IC if shorted you got protect warning..

I have an Onkyo TX-DS747 & everytime I turn the receiver on the speaker outputs a switch keeps turning on & off for about an hr before it rectify it's self. Is there a way to correct this issue??...


What it sounds like you are describing is the protection relay turning on then imediately turning off for the time period mentioned. That would indicate a possible short in the circuitry. Probably a capacitor that is intermittant or even a transistor about ready to fail. This is probably not something you can look for if you are not an electronic tech. Find a reputable shop and get it fixed before it quits and does more damage. Let me know how you make out.

Tx-ds747 no display light,when powering on only stand by mode and the volume knob has light ,how to fix it.


Sounds like the "Pure Audio" mode is turned on. This mode is designed to use the amps power to dedicate to audio processing and sound quality. It turns off all front panel lights and video processing. Check you remote or thr front panel of the Onkyo for a "Pure Audio" button.

My unit switches between speakers A, B and neither, while warming up. Lasting anywhere from 5min-15mins until it settles. Then speakers A can be selected and it will stay there. How do I fix this?


I see that I am not only one with same issue with TX-DS747, and would be grateful if someone could post some more info about this problem.
