Hello,
So we've been programming DP710 with this same code for years without issue. Then yesterday we went to program a display, it started up alright showing the Danfoss logo, however; after we were done programming it, no images show on the screen.
We thought maybe the display unit was damaged so tried another one, same issue.
You can tell the backlight is on and we still have communication with the buttons. We can also see that the logic of our program seems to work as we can go through our menu on service tool but nothing shows on the display.
Also, not sure if relevant, but we noticed that the screen was getting abnormally hot during testing, at least to 100F.
Any help is much appreciated,
Thank You
