NR1501. No sound at all.

[Tonke]

Hi.
This receiver has no sound at all, also not on the headphones. In the service mode is said: check DSP. I have added 2 1000uf 16 volt caps one at ic 1006 and a other one parralel to C1204 on the DSP. I also found out the 5 volt was only 2,1. So I swapped the IC201 5 volt regulator. 5 volt is now ok.
I am looking for the update software cable and software itself. There is no DSP ROM value seen in the service mode. The field is empty. So there might be a update necessary. Can anyone help me?
Merry christmas!

Hmmm, you seem to know a couple more tricks than I found.

For those with an eye for detail: service mode values I found:

Firmware: 090921-1
DA: 9-2
DSP: (empty)
HDMI: 10042011
