Shield compability with arduino MEGA, motor Shield , and 4DSystem screen shield

[flowwww]

Hello
I have a new projects with different motor and an LCD display

I use the following material:

Arduino MEGA
screen gen4-uLCD-50-DT
shield 4D syhstem E198919
motor Shield HW130 L293D

Apparently the shield for the motor and the shield for the screen use the same pin on the arduino, therefor i can't use them together.
When i activate the motor shield the screen stay black.

Do you know if their is a way to use them together? Like allocate different pin with jumper cable...?

thank you

I'm missing the links to the schematics of the used components in your post.

Thank you very much

The motor shield and the 4D adapter shield collide on pins D3 and D4.
