You don't need Schematics for some Basic Things and for Medion there is rarely Something Like that available.

Start with Sharing a HQ Picture of the internal Display Connector.

The easy way Would be to Check with another working Display First before troubleshooting the motherboard.

The simplest way:
01.Check whether its LVDS or edp
02.Check no of pins on lvds/edp connector-30 or40 pins.
03.Grab any schematic with similar connector
04. Now you can check what is missing.
