Basic Precautions
1
Before repairing, record the information below.
Lamp time, Unit Time, ERROR code (total of ten)
2
When replacing the main PCB, input the lamp time and unit time again (to correctly figure out used hours of
the lamp or the OPM unit).
3
If the projector does not boot normally and the lamp time and the unit time are not known, check with the
user about the approximate hours (Especially if the lamp time is set to 0, "replace lamp" message will not
appear at a correct timing.)
Even the approximate hours are not known by the user, input from 50 to 100 hours as the estimate.
4
When replacing the lamp with a new one, input 0 as the lamp time. When replacing the OPM unit or main
PCB with new ones, leave the unit time as it is.
5
Custom logo is not cleared by "Initialize ALL". It has to be initialized in the Custom logo menu.
6
When replacing the main PCB whose custom logo is set by the user, the custom logo cannot be transferred.
Tell the user that the custom logo has to be set again.
