Cleaning The Rgb Panels - Sanyo PLV-Z3000 Service Manual

Maintenance and Cleaning

Cleaning the RGB panels

Blemishes such as dust and dirt on the internal optical components of the projector tend to degrade the brightness of
the screen and are likely to appear as a shadow on the screen, which can lead to deterioration of image quality.
This projector is equipped with the RGB panel cleaning holes on the bottom for cleaning of the internal parts (such
as optical components) of the projector. When you use the projector for a lengthy period of time or a shadow of dust
appears on the projected screen, clean the inside of the projector.
Using the supplied air blower and with the Cleaning function in the Setting Menu, you can remove the dusts from the
projector.
Note:
✔
• Dust might not be removed completely with these steps. In that case, contact the dealer where you purchased the
projector or service center.
CAUtIoN IN USING tHE AIR BLoWER ANd tHE NoZZLE
● Turn the projector over when using the blower.
● Use only the supplied air blower and nozzle to keep the projector from being out of oder or damaged. We
CAUTION
could not guarantee the malfunction or breakage caused by other tools.
● Never use a commercially available compressed air duster. It causes the interior of the projector to
malfunction with release of cold liquid propellant.
● Put the projector on a soft cloth to prevent scratching the surface.
PROHIBITED
● Open the hole cover only when you clean the inside of the projector.
● Do not look into the holes. A strong light could damage your eyes. (Do not look into the Air intake vent and
Exhaust vent, either.)
● Use the blower and nozzle only to clean the projector. Do not attempt to use them for other purposes. Do
not use the blower and nozzle against persons (particularly to eyes, mouth or ear, and so on). Be especially
careful to ensure that children do not put the blower and nozzle into their mouth and swallow them.
● Do not attempt to pull the nozzle out of the blower. If the nozzle happened to be pulled out, put it back
into the blower immediately.
● Do not use the blower supplied with this projector (model: Z700) to clean the other models: Z4, Z3, and
Z1X.
In the unlikely event that something goes wrong (smoke, a strange sound, an abnormal odor, and such) while you are
cleaning, turn off and unplug the projector immediately, then call the dealer where you purchased the projector or
service center.
