You didn't mention if you tried adjusting the display density dial above the "Accessiblility" key or if you verified the operation panel is mounted correctly and the cable is installed correctly during setup. Did you dheck the operation panel cable connector and verify the pins are not damaged?

I would try these first before messing around with the boards. If this is a new machine I would also get on the phone with Konica tech support to document this problem for any warranty claims.

Try replacing/swapping the DIMM on the MFP board.

Hate to state the obvious, but bad display? Had to replace a display on a different machine that uses the same display, same issue.

We have had issues with our setup guys not securing the screws that hold the VGA cable in place. Have you checked to make sure they are fully tightned? When you tried to reload f/w, did the display come up? Emujo
