1. LAMP STRIKE ISSUES ON DP2K-XXB SERIES
1.1 General
Phenom enon
Some DPK-xxB projectors have problems striking the lamp.
Cause
The cover plate of the SPG inside the projector has an effect on the m agnetic fie
ld created
by the coil in the SPG (start puls generator). This causes a loss of energy that r esult in a
lower ignition voltage.
Solution
By removing the inner cover plate you can increase the ignition voltage. This results directly
in an easier lamp strike.
Scope
All DPK-xxB projectors.
