LCD12864 not working on MKS_base motherboard

I used my LCD12864 Full Grafics on my Melzi 2.0 ( Arduino 1280) and was working always fine for a year now .

Now I upgraded my motherboard to a Xinray board ( Melzi update board ).

I neaded this for more memory on the Arduino 2560 ( compatible with Ramp 1.4 or MKS BASE) and the LCD12864 is not working anymore .

The settings are correct in Marlin 1.6.0 with the newest 8glib software inclosed

When i connected the two flat cables on the right position EXP1 and EXP2 , the display is frequent ligting up on the with a tikking sound on the beeper ( the LCD is not broken and working still on the Melzi 2.0

I used several LCD configurations in the Marlin software with the same results.

Is there a incompatible problem with the 10p headers on the Xinray perhaps or is there a other issiue , pin configuration settings in the Marlin ?

If the board is MKS_compatible, you'd need a LCD from MKS-Base or find out, how to connect the reprap-LCD with jumper wire.
Last time I read abut it, some users where trying to find the pinout of the MKS headers.
