My receiver went no sound, and I have checked the debug code it should be something to the DSP. However, after replacing the DSP with a newer version(D808K013DPTP4) still no sound coming out and also the DSP version are all question marks. I checked the signal path between MCU and DSP by a oscilloscope and it seems DSP has outputs to MCU but MCU keeps sending RESET signal to DSP. So I assume DSP works so only thing to doubt is the firmware(which could be corrupted??? I can't believe). I see there is 8 pin SPI flash on the board and I dump the data and it looks there is something weird in the end of the data. I'm running out of idea. Just checking if someone owing the same model has the firmware dump? Really appreciated!

Similar models with the same firmware:TX-SR309/ HT-R290/ HT-R390/ HT-R548/ HT-RC330

I also own a Pioneer model which has the same DSP chip and I copied the firmware and flashed into the Onkyo receiver, it doesn't work as well. If someone needs the firmware for Pioneer VSX323 I'm happy to provide.

retiredhvac: Onkyo TX-SR353 Service Manual Request. Tried to contact forum member who offered it but no reply. This unit may share identical traits with a Pioneer.
