Waters detector turning off and then turning back on

All,

Our Waters 2487 dual absorbance detector is turning on and goes through the warm up but then shut off right when it gets to the "homing optical filter" verification stage, and then it turns back on and repeats the cycle.

I've changed out the lamp but it's still behaving the same way. Would appreciate it if anyone could offer some suggestions on what's causing this issue, in particular, if you've had similar experiences with the detector.

Would appreciate it. Thanks.
Hi,

The issue is with your LVPS unit. It needs a new Low voltage power supply (LVPS). Contact your local Waters service department or who ever looks after your service.

This has been discussed before. This link should help you out.
