How to fix a Waters 2489 front panel display that doesn't illuminate?
If the front panel display of your Waters Security Sensors fails to illuminate, check the electrical connections first. If that doesn't work, check and replace the fuses if necessary. If the problem persists, it could be a bad LCD or control board, and you should contact Waters Technical Service.
Why doesn't the deuterium lamp light on my Waters Security Sensors?
If the deuterium lamp on your Waters Security Sensors doesn't light, there are several potential causes. First, the lamp itself might be faulty and need replacement. Ensure the lamp connector is properly plugged in. There could be an issue with the lamp power supply board, in which case you should contact Waters Technical Service. Also, check the rear panel connections and timed events within a method, as they may be programmed to turn off the lamp.
