devolegf check the HT supply to the Deuterium lamp and also make sure the order filter is clean and the solenoid is freely moving. The Du lamp is responsible for the 190nm to 420nm and the tungsten lamp from 380nm to 1100nm my experience with these old school spectros is the Du lamp is not striking, thus there's no energy for the self calibration procedure
This unit does not have a deuteruim lamp it has a 12v 20w tungsten halogen lamp. This is either a display PCB fault or possibly a keypad fault. Unplug the keypad and try to switch on again.
Looks like the Deuterium lamp needs replacing? or the order sorting filter isn't moving out of the beam.
The lamp was replaced, the result is the same.
