MDT947B-1A Mitsubishi monitor is one of the earliest generation Mitsubishi monitors. This monitor was fitted on Fanuc controls. The MDT947B-1A is a 9″ Green monochrome CRT based, though amber mono variants do float around. DNC has been offering exchange and replacement on this monitor since 1994.

Most of our customers opt for the service exchange MDT947B-1A @ £245.00 GBP available today. We strip and clean the monitor, repair the circuit and replace the CRT with a new tube – looks great. Hence it offers the best value for money for 30 year old CNC machine tools, and carries a 180 day warranty.

The replacement for this is aptly named the DNC 92B. We can do either a CRT based DNC 92B (which we are phasing out) @ POA GBP (1 Year warranty – While stocks last). Or new DNC 92B replacement which is LED based @ £695.00 GBP (2 Year warranty). The replacement DNC 92B is an equivalent replacement monitor for the Mitsubishi MDT947B-1A monitor. It will physically and electronically work in Fanuc system 6 series controls fitted with the MDT947B-1A.
