Pioneer VSX-D850S audio output delayed?
Hello: I am trying to repair this receiver. All channels work ok until you
change dsp modes . There is a audio output delay of 10 to 40 seconds. Then all is ok again. Same problem if you turn loudness on -off. I have switched the dsp board with a working one, same problem.Anyone have any ideas or where to check or a service manual or schematic. It appears to be almost the same as a VSX-D810S. TIA Mike |

There is a service bulletin which refers to the DSP, but since you've already swapped that out, I don't know if it applies to your situation. I do think I'd look to see what the muting transistors are doing. Do you have the manual? If not, it's about 6 meg or so. Can you take an attachment of this size? Mark Z. |
