NVRAM mismatch c534n

[BlakeryBob03]

I have a c534n laser printer. The display quit working. I bought a used display, i get the 950.10 nvram mismatch error. So i bought the system panel out of the same used printer and installed that. So the display panel and the system panel are out of the same working printer. When i fire up the printer, i still get the 950.10 nvram error.

When i put the old display back it, and leave the newer system board, the printer works, but no display.

Is there a way to clear the nvram and have it pair the system board and the display back together?

Any help would be great!
