My XBTGT series HMI was indicating a burned out backlight, but when I replaced it, the screen still does not function. Why?

The Backlight burnout indicator (Solid Amber LED on Bezel) means either the backlight is burned out or that the inverter board may be bad. The inverter board is not field replaceable and the complete XBTGT will need to be sent in for repair. Please ensure that you have a backup of the HMI program before you send in your HMI. To arrange for repair please call 1800-468-5342 and use option 2.
