LCD screen only showing rectangles?

I got the mk2 to mk2.5s upgrade and just finished putting it together. But when trying to flash the firmware, the LCD screen just shows rectangles, even though I flashed the correct firmware. I attached an image of the screen...any ideas as to why it isn't working? I have checked the wires, everything is plugged in. The screen was working before the firmware update. Thanks so much for the help!

RE: LCD screen only showing rectangles?

I upgraded firmware, and downgraded it, no-joy with either.  Finally broke down and ordered a replacement screen from Prusa, now it works well.

No clue as to what happened.
