Just witnessed this problem with our old Agilent 1100 VWD. All the modules on the HPLC tower would initialize fine in Chemstation, but when the pump, column heater and VWD is turned on, the VWD would take a long time to initialize and eventually fail. Looking at the D2 lamp through the little port shows that power is going through the lamp (hence not dead) but it would shine bright, then dim significantly but to a steady faint glow, then shut off after 1 min or so. In addition, a weird phenomenon is that when the lamp error pops up, which says UV lamp failed to ignite, a "run" starts and the pump and column heater display turns blue. I don't think this is normally what happens when there is a module failure on the Agilent HPLC. Any ideas? Suggestions?
