DNS part numbers EEMP-0021X3 and EEMP-0013 are LCD monitors that can be used in either the 60A, 60B, 80A, or 80B tracks, depending on the track configuration.
These can fail or malfunction if installed in a tool not configured for that exact part number. EEMP-0021X3 is a full color display, whereas EEMP-0013 is a monochrome display.
A known symptom of color vs. monochrome incompatibility is loss of directional sync on the monitor. The screen image will continuously and uncontrollably “roll” like the images in a slot machine. Another failure symptom is no image at all, but this is less likely a compatibility issue as opposed to general circuit failure. In either case, GetSpares.com maintains a fully operational DNS 80B track and parts, as well as the capability to repair and test parts. If your DNS LCD monitor is failing, contact GetSpares for quality repair/replacement solutions.
