I have a E300 Beijer HMI conected to Mitsubihi PLC FX1. Everything seems working ok, but today the HMI just doesn't show anything on the screen, seems like just the backligth is working.....I checked voltage and is fine in the terminals. Is there any special key to press and bring the letters back?????.....Have somebody experience this before with this HMI???....
