Cleaning and Maintenance
Once the WN-5230-S is set up and adjusted, periodic maintenance will
consist of cleaning the display and replacing consumable parts such as
the lamp and filter. Use the procedures in this section to remove and
replace WN-5230-S modules as needed to maintain trouble-free
operation.
Lamp
Before you remove the lamp, switch off the WN-5230-S with the remote
control, or press the black POWER button on the electronics module,
and allow the lamp cooling cycle to finish (30 seconds). Then switch off
the power at the rear panel AC switch.
CAUTION The lamp is very close to its cooling fan. This fan does not
stop when the lamp turns off or after the cooling period. It is
always running, unless power is removed from the whole unit.
When you remove the lamp, your fingers may go into the
moving fan. Whether you replace the lamp from the front or
from the rear, remove the power cord or switch off the power
at the power input on the rear panel, before removing the
lamp.
The WN-5230-S has three screen options:
• The standard screen has a mullion about 1/8
th
inch (3 mm) wide.
The mullion is a strip of sheet metal surrounding the screen which
holds it in place.
• The Ultra-Thin Mullion Screen, or mullionless screen, does not
have the 1/8
th
inch strip of sheet metal around the screen. The
viewing area of the screen goes right to the edge of the display
unit. This makes the lines between display units much less
apparent in the finished video wall.
• Blackscreen, like the Ultra-Thin Mullion screen, but looks black
when no signal is applied.
With standard screens, electrical interlocks prevent operation when the
front screen is removed. Do not operate the display with any access
