WARNING
Before attempting to remove the lamp module, switch off the WN-5220-V with the
remote and allow the lamp cooling cycle to complete (3 – 4 minutes) before
switching off power at the rear-panel power switch. The lamp module may be
removed and replaced from the front by first removing the screen, or from the
rear by removing the lamp service access cover.

WARNING
Some circuits contain line voltage when the WN-5220-V VideoWall is connected to the
electrical mains, even when power is switched off. Before servicing the VideoWall,
always switch the AC power off at the rear-panel power switch and remove the power
cord or switch-off the circuit breaker that controls the VideoWall.

CAUTION
Do not touch the glass portion of the lamp or reflector. Oils from the skin will cause
these surfaces to become etched when the lamp is operated, dramatically shortening the
life of the lamp. If lamp should be accidentally touched, clean it with isopropyl alcohol
and a soft cloth.
1. Turn off the power
Switch off the WN-5220-V using the remote and allow the cooling cycle to
complete (3 – 4 minutes) before switching off the AC power at the rear-
panel switch.
2. Unplug power cord
Unplug the AC power cord from the WN-5220-V.
3. Remove screen or lamp
access cover
To gain access to the lamp from the front of the VideoWall, remove the
screen first.
To gain access to the lamp from the rear of the VideoWall, unfasten the 8
quarter-turn screws on the lamp access cover and remove the cover.
4. Unplug high voltage
lamp connector
The lamp connector is next to the reflector fan. Unplug the connector by
pulling up on it.
5. Unhook the lamp
Unhook the two latches holding the lamp module to the optical assembly.
6. Remove the lamp
Lifting up on the lamp handle, tilt the lamp module away from the latches
until it can be pulled free of the optical assembly.
Carefully remove from the VideoWall by lifting the lamp module straight
up to clear the fans, and then withdrawing.
7. Replace the lamp
Replace the old lamp module with a new one.
8. Reset the Lamp Hours
Reset the lamp hours in the menu.
Replacement is the reverse of the above procedure. After installing the lamp
module, ensure that the high-voltage connector is securely in place and that the
latches are securely latched before replacing the screen or the lamp service access
cover.
