GT2560 + lcd12864 encoder scroll problem

[polovi]

Hi,
i have working GT2560 with reprapdiscount full graphic smart controller. Everithings seems to be OK, dispaly working, beeper working, touch down encoder as selectworking, but scrolling in menus or change value didnt work. In RAMPs based board encoder works and i can scroll normaly.

Does anyone idea where could be problem? thanks

Maybe one of the two cables is not connecting well,as i know,one is for "clicking" and the other is for "scrolling".
