Bluesound Powernode N180 PSU failure

Dear Forum,

Trying to repair a Powernode N180 with power failure. This is an early generation (second?) of the Bluesound Powernode.

The problem manifests itself by the infamous “red Play/Pause” button. This version has a combined PSU/pre amplifier board.
I have replaced most (large) electrolytic capacitors in the PSU, as these were “bulged”, completely dried out and no capacitance at all.
After the repair and switch on, strangely a small capacitor blew up on the Hypex NC102 power amplifier board. After that all elco’s on the NC102 were also replaced.

At present the Powernode is mostly working again: staring up normally, can be seen from the BluSound app, music can be streamed and headphone output working.
Only the NC102 power is not working. It appeared that +/- 42V power is missing.

It is very hard to debug this failure, as traces on the PSU board cannot be traced on the PSU board. Probably an active element in the switched power supply has failed.

Can someone help me with a schematic diagram of the Bluesound Powernode N180?

(if copyright issues prohibit this, please send me a DM).

Many thanks in advance,
