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 on how to get this printer back online?

Re: GT2560 Board not responding!!
Hi,
First did you rewire the board during the moving(maybe wrong connection?)?
You can try unplug all the cables on the board except the power cable and LCD cable to see if there is a difference.
After that,you can try reflashing the firmware again with Arduino 1.0.1.

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