The following keys are available in the Video menu:
r — Returns to the Individual Diagnostics menu.
v — Runs the power-ON video diagnostic.
m — Runs the video memory diagnostic. This test is a more
extensive test than the power-ON video memory test. This test
could take up to five minutes to complete.
d — Shows the display registers.
For product test only- it is of little use in the field.
i — Runs an interactive video diagnostic, which displays red,
green, blue, white, and black screens, for five seconds each.
Inspect the screen for faulty pixels.
Error Log
To troubleshoot intermittent problems, the monitor maintains an
error log for both recoverable and non-recoverable errors in its
battery-backed, non-volatile memory (NVRAM). All diagnostics
failures are logged in the error log.
Most errors relate to the CPU PCBA, but parameter modules or
software errors can cause errors. For example, a particular sequence
of key strokes that always produces the same error code could be a
software problem.
Refer to the XPREZZON and qube System Administration Manual
(P/N 070-2380-xx) for monitor configuration of the System Info
and Error Log tabs under Privileged Access.
