4.8 High Voltage Power Supply

These connectors may be difficult to remove and it may
be necessary to angle the LVPS partly out of the
chassis in order to get a firmer grip on the connectors.
5. Remove the 2 screws on the bottom side of the LVPS
and carefully slide it out of the projector.
6. Reinstall the LVPS in reverse order. After the LVPS is
installed, recheck Timing, Geometry, Electronic Focus,
®
ILA Bias/Sensitivity, Convergence, G2, and Shading.
To remove the High Voltage Power Supply:
1. Remove the front and rear covers (Section 4.2).
2. Remove the High Voltage Power Supply cover (Figure
4-5) by removing the 2 pozidrive screws that secure
the HVPS at the top of the cover and loosening the 1
pozidrive screw at the bottom of the front flap (Do not
remove this bottom screw-it is difficult to reinstall. The
HVPS will slide up and over it).
