Elektronik Saeco incanto s-class contrast issue on lcd

[StefanVs]

Hi all i have a saeco incanto s-class sirius and yesturday lcd started to flicker allitle bit and in a few hours became dark so dark i can barely see from some angles . the machine works fine and when is a power consumption from the machine the lcd turns lighter and i can see allitle better. Does anyone have a electronic schematic or pinout of the LCD and bord to identify the contrast pin.

Kind regards all

Check the ribbon cable from Display. Check the hot water valve for leaks, Check the circuit board for traces of water

sorry there are no schematics, but follow the the hints from Uhrmacher, hope they help. As he said mostly a contact problem.
