MX-2640N Static display panel

[Jammed]

The op panel is like an old TV set when it goes off air. Very colorful static lines fill the display screen.
Replaced the op panel PCB, no change. Replaced the 5V PCB under the op panel board and the screen goes black and stays black. Only thing left is the scanner board on the copier rear wall... ?? Any ideas? TIA

Try reseating the connection between the MFP PWB and the mother PWB.

Turned out to be MFP Brd.....
1. Screen would display static pattern, however would work, the button mapping remained intact.
2. When you remote into machine via VNC the remote image would display correctly

I had that problem before, but I was ale to get into the web interface and update FW. And it fixed the issue.
