Komatsu 7835-31-1003 is the colour cab monitor with function keys and a separate air conditioning keypad, on a cast aluminium finned rear housing with two white multi pin connectors. It is used on Komatsu PC200-8 to PC290-8 excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Blank or flickering screen
A monitor that stays dark, flickers or shows lines once the fuse, power and earth at the plug check out has failed inside. A new unit brings back the gauges and warnings.
Dead buttons or no warnings
Worn keypads stop mode, speed and menu changes, and a failed monitor can miss engine and hydraulic warnings. Replace it before a warning goes unseen.
Water and sun damage
Cab monitors take heat, sunlight and water from open doors and windows. Fogged or cracked screens and corroded plugs are common on older machines.
Fitting tips
Disconnect the battery, compare the plug and the label on the old monitor with the new one, unplug and unbolt the old unit, then fit the new one and check every gauge and warning with the engine running.
