What to do if the ISCO Measuring Instruments display is blank but there's a beep?

If the ISCO Measuring Instruments display is blank but you hear a beep when pressing a key, it could be due to the contrast being out of adjustment. Try adjusting the display contrast by repeatedly pressing the up or down arrow while holding down the +/- key. Alternatively, the display might be faulty, in which case you should replace it with a known good display.
