By means of a dongle for the USB interface, TNCremoNT can be enhanced to
TNCremoPlus. With this version you can view the control display on your service laptop.
You can call this function with the icon View TNC screen.
The symbol is part of the menu bar, next to the camera symbols.
The dongle can be ordered from HEIDENHAIN.
If you can see the display information with TNCremoNT, it is still not 100% sure that all areas

If you have found out that the screen itself is defective, then a further inspection of the
flat-panel display is not possible without special test equipment.
