Yeah the help documents are not very good. Was my first time using vijeo and not a great experience.
I opened the panel and removed the backlight. Then slid a LED strip in its place, powered externally by the way. Works quite well actually. Not sure why they still using the current backlights that constantly fail.
By default panel goes to error if backlight is broken.
Panel have setting for running also with broken light, but how to change from settings light error function, if panel have allready broken light.
Original HMI programmed knowed that setting, otherwise your panel should have to error with externally powered led.
Thinking that panels are prepanded profaces, at least some of them.
