HCM1011121BCHA is our most popular TFT LCD monitor that replaces the monitors used in all Charmilles machines that were fitted with the old, original 14″ tube monitors (except the Roboform 20/22 and Robofil 290/295/310, and Fanuc controls.) . This stunning, new monitor gives a welcome facelift to your machines with a crisp, clear display which your operators will appreciate.

The new monitor is mounted to the front door using the front mounting plate provided in the kit. This frees up valuable space inside the cabinet where the old monitor used to sit. Then simply reconnect the original cable to the adapter cable supplied and connector the power cable.

I got a Universal MLD Slant Igt with a Bad Monitor . The Monitor is a Kortek KTL220MD-04, the 3D monitor. The issue with the monitor is that it has a bad front panel , to make sure it was the panel  I swapped the video boards and it did the same thing and I even swapped the front panel with the back panel and the good panel came up while the bad panel kept on glitching.
