11. DLP (Digital Light Processor) PROJECTOR
(52” = LG, 62” = Mitsubishi, LG, TOSHIBA and ZENITH)
If the adjustment method in this manual does not resolve the problem contact the customer service number in this manual or your supplier.
“Snow” on the screen/changes in brightness for a short period are due to the high pressure mercury lamp in the projector. This is not a
defect and does not need repairs.
The life of the high pressure mercury lamp is the average number of hours 50% of lamps last for. Therefore a life of 8,000 hours does not
mean that the lamp cannot last beyond 8,000 hours. There is no way of knowing when the lamp is going to cease to function. Once it ceases
to function, the projector will be unable to display anything and the product cannot be used. Have a spare lamp ready at all times.
Do not stick tape, stickers or anything else onto the screen. Any kind of adhesive may damage the surface of the screen.
The projector remembers adjustments.
If there is any distortion, etc. that requires adjustment on the TEST screen, use the remote control.
The average life of the projector’s high pressure mercury lamp is approximately 8000 (50% survival), but the its actual lifespan depends on how it
is used etc.
The lamp will not last forever. If the screen is dark or continually disappears the lamp must be changed immediately.
Follow the procedure as outlined in the projector manual to change the lamp and be sure to reset the timer setting.
11-1 CLEANING
THE
SCREEN
Since the Projector screen is susceptible to damage, pay careful attention to
its handling. When cleaning, refrain from using water or volatile chemicals.
When the screen surface becomes dirty with dust, etc., clean it by using a soft cloth such as
gauze. When water, and volatile chemicals such as benzene, thinner, etc., spill on the screen
surface, it may be subject to damage, therefore, do not use them.
Also, since the surfaces are susceptible to damage, refrain from rubbing them with a hard mate-
rial or using a duster.
If the screen is especially dirty, call in a professional cleaner.

12. REPLACING THE FLUORESCENT LIGHTS AND LAMPS
When performing work, be sure to turn power off. Working with
power on can cause electric shock and short circuit hazards.
The Fluorescent Lamp becomes very hot and can cause burns if
touched. Be very careful when replacing the Fluorescent Lamp.
Be sure to use lamps of the designated rating. Using lamps of undes-
ignated rating can cause a
fi
re or malfunctioning.
Be careful not to damage the wires. Damaged wires may cause elec-
tric shock or short circuit or present a
fi
re risk.
To perform work safely and securely, be sure to prepare a stepladder
which is in a secure and stable condition. Performing work without
using the stepladder can cause violent falling down accidents.
Be careful when handling the plastic made parts. Failure to observe
this may cause injury due to damage or fragments resulting from
damage. Make sure that the prop is
fi
rmly in place before starting
any work. If the prop comes loose the control panel may close caus-
ing an accident.
