P7000 Single Channel dies

Hey Walker or whoever can help,

My P7000 recently started to drop out on the LVM channel. When I do a cleaning, the nozzle check is perfect but then when I run a print, the channel dies during or after with now lines in the nozzle check. It seems as if it is loosing pressure and ink is not getting into the damper. I was considering replacing the damper unit to see if that fixed the issue.

Any insight?
