LCD 2004 Screen for A10 A10M A10T with GT2560 V3.1 or V4.0 Board, 2*10 Pin LCD Cable Connector at Backside of the Screen

_br_Hello Geeetech Support,_br_I recently received a MeCreator2 as a gift for our men's shed, and as someone who builds 3D printers, I'm having some trouble with it. I noticed a hole in the ribbon cable of the screen, so I replaced it with a 600mm long new one, but now I'm only seeing two lines of four on display. I also cut the old cable, so I can't trace the fault. I reinstalled the firmware from your site of GT2564 Rev. B without a problem, though altering the number of steps per unit on the Y axis didn't make any difference in the movement of the Y axis._br__br_I would really appreciate any advice you can offer._br__br_Thank you,_br_Istvan
