Default Service mode for Dell Ultrascan P991

From memory this monitor has no service mode to speak of. There are failed
components causing your fault. Sometimes it is the high voltage multiplier,
and or sometimes it is also some of the capacitors in the HV and scan
circuits.

As for any service set-ups you will require the DAS alignment system with
the software and interface. There is also some factory training and proper
instrumentation required to do this type of work. This is available to
authorized service centres only. The cost of this system is far greater
than even buying a number of new montors. The unauthorised centres job
these types of monitors out to the factory service if this level of service
is required, and bill the customer accordingly.
