We are trying to resuscitate a G1956A MSD. Recently replaced power supply which got the heaters working but MSD still not ready. On running diagnostics, got an MS Ion Optics Test Failure:
Ramping Test Error: Not enough signal at m/z 1218 for ramping test.
(see page 8 of attached).
Not sure what next steps are. Can anyone suggest how to troubleshoot this?
