Follow these steps to remove the screen, if the display unit is
not
part
of a video wall. Read all the steps before starting.
1. Grasp the screen on
each side at the
bottom
The “screen” you are removing is approximately 2 inches thick.
Pull out at the bottom first, to separate the latch-hooks from the
latches. The screen should now be loose at the bottom, but still
attached at the top.
2. Slip fingers between
the screen frame
Slip fingers between the screen frame and the VideoWall
chassis as close to the top latches as possible and pull the top
of the screen from the latches.
3. Using both hands…
Carefully remove the screen and set it aside.
4. Reinstall
Reinstall the screen by lining up the latches and pressing the
screen inward. It will go in with a distinct “pop.”
Note:
To remove the screens from a video wall configuration, where each
unit is tight against its neighbor, it will be easier to remove the screens
of the adjacent displays to allow access for your hands to the screen
frame.
There is an optional screen removal tool available, the SRT-100. This
tool allows you to remove the center screen of a video wall without
removing the surrounding screens. Contact Clarity Visual or your
Reseller for more information.
Lamp
The lamp must be allowed to cool prior to removal. Wait at least 3
minutes after turning off the VideoWall to remove the lamp.
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 (see Screen on page 45), or from the
rear by removing the lamp service access cover.
WARNING
Before servicing the VideoWall, always switch the AC
power off at the rear-panel power switch and remove the power cord.
When the WN-5220-V VideoWall is connected to the electrical mains,
some circuits still contain line voltage, even when power is switched
off.
CAUTION
Do not touch 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.
