Lamp Replacement Procedure
CAUTION: The light source lamp produces extreme heat. Allow a cool-down period before
touching or replacing the lamp assembly.
Note: For protection, the lamp circuit contains a “normally closed” switch. Therefore, the lamp
will not operate with the lamp access door in the open position.
Note: There are no tools required for this procedure.
To replace the lamp assembly, slide the access door on the rear of the unit to the right. Unscrew the two
silver thumbscrews holding the assembly in place. Slide the old lamp assembly out by crisping the “metal
handle” and pulling straight out. Install the replacement lamp assembly by pushing into place and
tightening the thumbscrews. Slide the Lamp access door to the left to close
. “The unit will not operate
with this door open.”
Light Engine Replacement and Focus Adjustment Procedure
CAUTION: Do not remove the three “silver” nuts and washers as these hold the Light Engine
support bracket and are critical adjustment points for focus and picture alignment.
CATUION: The Light Engine has an operating voltage of approximately 1,000 volts. Always use
caution when working in the vicinity of the Light Engine while the unit is in operation.
The LCoS Light Engine comes pre-adjusted. No adjustment for focus should be required. In rare cases,
the set may require a minor focus touch up.
Due to screw placement, to replace the Light Engine, it is necessary to remove the upper-back before
beginning the replacement. Use care with the routing of the wiring for the Customer Keypad when
replacing the upper-back. Also, note mounting direction of the Upper-back support bracket for proper
re-installation.
To remove the Light Engine, remove the three “black” T-10 Torx screws located in the vicinity of each of
the three “silver” nuts and washers. The front Torx screw is located directly beneath the 10mm wide,
white clip, located on the top front of the Light Engine housing. Re-install the Light Engine in reverse
order.
Light Engine Focus Adjustment and Alignment Procedure
To access the Focus Adjustments on the Light Engine, it will first be necessary to remove the Speaker
baffle. The baffle is removed by gently prying and pulling with the finger tips. Care should be use not to
damage the plastic retainer pins.
