Display blank – EDM has power

August 17, 2012 by Craig Peyton

If there is a light in each upper corner then the CPU has failed – return for repair.
If no light, then the display is cracked – return for repair. Visit: https://www.jpinstruments.com/jpirma/ for a RMA number before sending it in.

Check RPM sensor if applicable – if shorted together will kill EDM display.
