E7 25 LSU LD DRIVER ERROR (C)

Clean all mirrors in the LSU.
Change the little circuit board at the LSU.

[dwarf]

exactly where is the board mounted?...inside LSU?... could you provide a P/N?

[dsmith46]

The board is mounted on the outside of the LSU I believe. The p/n is: CPWBX2026DS53.

Good luck,
Dustin

thanks for the help Dustin but that didn't work any other ideals what would cause an error code E7-25

[dsmith46]

I would try replacing the entire LSU if it were one of my machines.

Good luck!
Dustin
