The D5000 error report would point you at the safety ciruit, and the
bulbs are the first thing to check. It's part of the safety
specification that a warning lamp failure prevents HT operation - EU,
UK, and most other places.

Our old PW1730 generator driving two PW1050s has a similar system
with a warning lamp. It is part of our monthly safety checks to
verify that no bulb = no HT.

I'd endorse the D5000 recommendation, though we've only had our twin
goniometer system (general powder and grazing angle options) for a
couple of months. The software is less intimidating to casual users
than the Philips equivalent to my mind. But I wouldn't object to a
X'pert MPD system if it was offered! A lot depends on your
applications, now and in the future. And on your funding!
