Geeetech

I kept all connections intact.
I'll try removing all the wires except power and lcd.

I have the Prusa i3 pro b, it was working fine for two weeks until I moved it from my office to my home. Plugged it at home and got the two rows of black squares. I tried reloading firmware and it gives me error:
avrdude: stk500v2_ReceiveMessage(): timeout

Has this board gone bad so soon? Any help ...
