Identification LCD board from Buderus Mec 2

Hello,

i want to know the LCD 16x4 "Type"; manufacturer and controller from 
Buderus MEC2. The flex cable from LCD to the controller is defect.
The flex cable from main platine to controller has 18 pins:

Pin 1    -   Vss;
Pin 2    -   Vdd;
Pin 3    -   Vo
Pin 4    -   ?
Pin 5    -   ?
Pin 6    -   ?
Pin 7    -   ?
Pin 8 - 15   could be Data bus line
Pin 16   -   ?
Pin 17   -   A
Pin 18   -   k

maybe 2 special Pins for the Special symbols.

I hope i will get a other LCD who also works with MEC2.
I dont need the special symbols.

Thanks,
Done01
