DM2800 original controls, suddenly not working.
I was messing with the wiring on the touch probe, had it working but trying to get the LED to light by swapping some wires, might have crossed a couple bare wires or inadvertently grounded the hot (yes I had it plugged in at the time, but hey it's only 5 volts). I heard something "pop" and the pendant went blank. Off, on, nothing. Checked fuses that I could find (2 outside, 1 inside), all OK. There's so many boards in there I don't know where to start.

The motor fans and cabinet fans run, no lights anywhere inside. Spindle does not work. It is VERY humid here today. Bummer 'cause it WAS working so well.
ANY IDEAS? I know just enough about controls to be dangerous (obviously).

Looked at the schematic. distribution board driven by 5V power. located power bus, no 5V power. Looked for seperate 5V power supply, is it integrated with the Lambda power supply? Can I just apply 5V to the bus? How many amps?

I traced the 5V feed back to the Lambda ES-8-5 DC power supply.
Found one on ebay.

Replaced the 5V power supply. No change. Finally figured out my transformer is only putting out 38 volts (supposed to be 115V).

48V power supply has no output. Would like to find a direct replacement, otherwise it might be time for an UPGRADE.

Prior post about transformer was incorrect. I measured it wrong.
