I’ve got a TAZ 6 and I was pulling a piece of loose plastic from my extruder tip with metal pliers, lost my grip, and contacted something that sparked. Screen went blank.
Light on power switch turns on when activated
15 Amp fuse is undamaged
F2 and F3 Fuses replaced without fixing the problem
I tried to boot the control board with all the sensors/motors disconnected in case they were damaged and re-shorting the new fuses, but the board didn’t boot.
I Checked this page.

And it looks like the Rambo board is completely shorted out.
I think I’m going to have to replace the Rambo Board. Does anyone know a diagnostic check I can run to make sure I didn’t just fry the LCD screen or something similar before I replace the whole control board?
