Wrong ID Tag on MD4 Start up

When powering on the MD4 the system message "IQAN-Master Wrong Id Tag!" appears on the screen. This does not happen every time the machine is powered on but is getting more frequent. Restarting or shutting off the power to the MD4 does not resolve the problem consistently. The screen remains black when this issue happens. Any help is greatly appreciated.

sounds like a wiring issue- check tightness of all connections in address tag circuit- loose connection will affect the resistance leading to error detection.
Failing that try another tag?
The address tag is dependant on the +5v VREF in the MD4-7, so if you have anything connected (sensors etc.) to the +5v on the display, there could be an issue there that may affect the stabilised voltage.
