About the iiquid crystal display (LCD) screen
Small black dots or white dots (bright dots) may appear on the LCD screen. These are
due to the characteristics of the LCD screen and do not indicate a problem with the dis
play.
At low temperatures, the LCD screen may be dark for a while after the power is turned
ON.
The LCD screen will be difficult to see if it is exposed to direct sunlight.
Keeping the display in good condition
When removing dust from the screen or cleaning the display, first turn the system power
OFF, then wipe with a soft dry cloth.
When wiping the screen, take care not to scratch the surface. Do not use harsh or abra
sive chemical cleaners.
About the small fluorescent tube
A small fluorescent tube is used inside the display to illuminate the LCD screen.
* The fluorescent tube should last for approximately 10,000 hours, depending on oper
ating conditions. (Using the display at low temperatures reduces the service life of the
fluorescent tube.)
* When the fluorescent tube reaches the end of its useful life, the screen will be dark
and the image will no longer be projected. If this happens, consult your dealer or the
nearest authorised PIONEER service facility.
