Monitor care and repair Monitor care Troubleshooting Always remove the plug from the AC outlet when cleaning the monitor. Cabinet and control panel section Use a soft dry cloth to lightly wipe away any grime from the cabinet and control panel. If very dirty, apply neutral detergent to a dampened soft cloth, wring it out well and wipe away grime.
