The first MDT GlassTaster II Smart was broken last month. Fortunate there is a 3 year MDT warranty on it. I spoke to MDT and they said one or several Backlight LEDs are probably broken which gives a sort of rainbow effect. I post a photo below.
If anyone else have the same issue, you can recognize it. The display is at a steady 21degrees place and maybe it's touched once a month
