the UI processor POST or the system declaring a
system error because 3 resets occurred in the last 24
hours.
1. Examine the significant event log, check the recent
error codes and see if the Entries point to either a
Controller PCB, Controller subassembly or UI PCB
issue.
2. If this persists replace the UI PCB
3. If replacing the UI PCB doesn't fix the issue, replace
the controller PCB.
