Did that except cleaning the keyboard connectors if they were bad it would not perfectly work on MIDI I would think

Check. Replaced with known good power supply. Same thing. The power supply is actually
the same as the Triton and same model number


> It can be some crack on the boards, bad contact,


Checked for any cracks including all the chips.

That could be possible but only the DSP is not loading. Audio is working too all the time you can hear it.


> Maybe reloading of OS could help, too.



I think too risky. Right now it is a great organ controller THOUGH it could still be useful if it turned
into toast by stripping it out and rewiring to the HX3 but now it is 'plug and play' as Bruce said it can be set to about anything. However it would be nice to get the CX3 (that I think is still a great organ especially with a Ventilator or tube preamp)


> OS version can be found after starting this way:


It is version 2 without that "AB" suffix of a bad load. I have it apart right now so I can check exact OS later.

I will try the diagnostics again.
