Fair enough... on my S950 the LED below PLAY lights up red once I turn it on. Do you get any activity on the MIDI LED if you send notes to it?

I'm no expert, but I wonder if reseating cables might help... but that's a lot of work to get inside and get at the ribbon and other cables to try that.

Yes the PLAY light should be flashing when the machine turns on, now all lights flash up along with the power turning on and dead immediately. The floppy driver light is on for a moment when the power turning off. I assume there's nothing wrong with the power supply, but seriously bad on the board?

Usual behaviour on the S950
Power on
1) button LEDs and MIDI LED flashes 1 time
2) Floppy starts running and floppy led flashes
3) First button LED (PLAY) blinking

I think I have the service manual somewhere on my HD.
Upload?
peace
