Panasonic DIla PROJECTOR PT-D995U Operating Instructions

							Replacing the Light-Source Lamp (Cont.)
Loosen the lamp-unit screws, raise
the handle, and pull out the lamp
unit.
Loosen the two screws with a flat-end screwdriver.
Screw
The screws are fitted so that they do not come off the lamp-
unit.
Lamp unit
Insert the new lamp unit fully
inside and fasten the screws.
Fasten the two screws with a flat-end screwdriver.
Do not touch the glass surface of the light-source lamp
directly with your hand as well as staining it. If you touch
with a bare hand, stains on your hand may adhere to the
lamp, possibly preventing the lamp from performing as
specified due to a shortened lamp life, a darkened screen,
etc. To handle a new light-source lamp, hold its plastic
part. Never touch the metal part or the front glass
surface.Screw
Handle
Replace the lamp-replacement
opening cover and fasten the
screws.
Fasten the two screws with a flat-end screwdriver.

Lamp-replacement
opening cover
Be careful not to
damage the claw.
Install the lamp unit and close the lamp-replacement opening cover correctly; otherwise, a safety switch is activated
to prevent the projector from operating.
If the claw on the lamp-replacement opening cover is damaged, the projector may not possibly operate. Then, replace
with a new lamp-replacement opening cover.
After replacing the lamp, be sure to reset the lamp use time (see page 52).

							Replacing the Light-source Lamp (Cont.)
Resetting the Lamp Use Time
After replacing with a new light-source lamp, reset the counter inside the projector. This works to reset the life calcu\
lation of the
light-source lamp, allowing the used time of the new light-source lamp to be accumulated.

Turn on the MAIN POWER
to go into stand-by mode.
ON: The main power turns ON and the
indicator lights.
switch
STAND BY
Press and hold down the “VIDEO”,
“SETTING” and “QUICK ALIGN. +
” at the same time for six
seconds or more.
The STAND BY and OPERATE indicators come on at
the same time.
[Control panel]
STAND BY indicator
OPERATE indicator
While the STAND BY and OPERATE indicators are on, press
the “VIDEO”, “SETTING”, and
“COMPUTER” buttons at the same
time.
The STAND BY and OPERATE indicators blink two
seconds alternately, and after blinking, the projector
returns to stand-by state (the STAND BY indicator lights).
* This completes the resetting of the lamp use time.
To check the lamp use time has been reset :
You can check it by LAMP TIME on the OPTIONS menu.
After replacing with a new light-source lamp, be sure to
reset the lamp use time. When the lamp use time
indicates 1000 hours, and if it is not reset, the projector
does not operate. (The light-source lamp does not turn
on.)
Reset the lamp use time only when you have replaced
with a new light-source lamp. Never reset it at a halfway
time. Otherwise, the replacement time may become
unclear, degrade performance markedly, or cause lamp
explosion.

							Cleaning and Replacing the Filter
Clean the filter periodically. If the filter is heavily stained and does not get clean, or if it is damaged, replace the filter
with a new filter. Otherwise, dirt may get inside and appear on the screen, possibly preventing you from enjoying the
video image fully. If dirt gets inside or if you need information about the filter, consult a Panasonic-authorized dealer
where you have purchased the projector or nearest Panasonic Service center.
Turn off the MAIN POWER switch.
After the projector goes into stand-by state with the STAND BY indicator on, turn off the main power switch and pull out the
power cord from the projector and the wall outlet.
Remove the filter.
Loosen the screw with a flat-end screwdriver.The screws are fitted so that they do not come off the filter.
If the filter is clogged with dirt, etc., the projector goes into an
emergency mode (the EMERGENCY indicator blinks).
So, clean the filter periodically. For the emergency mode, refer to
pages 11 and 27.
Screw
Filter
Be careful not to
damage the claws.
Clean the filter.
Clean the filter with a neutral detergent, wash it in water, and then dry it in the shade.
Reinstall the filter.
Fasten the screw with a flat-end screwdriver.
Put on rubber gloves when using neutral detergent.
After you have washed the filter in water, make sure the filter is
completely dry before reinstalling it. Otherwise, electric shock
or malfunction could occur.
Do not clean the filter using a vacuum cleaner. Since the filter
is soft, it may be sucked into the vacuum cleaner or damaged.
Install the filter correctly. Otherwise, the projector does not operate.
(Goes into an emergency mode.)
If the filter’s claws are damaged, the projector may not operate. Then,
replace with a new filter.

Has the lamp life expired? (Has the
lamp use time reached 1000 hours?)
Light is not emitted,
or light level is low.Is the lens cap removed?
Is the lamp life near its end?
With power on,Is the air intake or exhaust area
operation starts butblocked?
stops in a few minutes.
Video image does not

appear, or audio sound does not occur.
Are connected devices connected
correctly?
Are signals being supplied from the
connected devices?
Are input signals (scanning frequency, etc.) appropriate?
Is the source setting correctly selected?
Is a wrong source (forced mode)
selected?
Is brightness adjusted correctly?
Is volume set at minimum?
Are video and audio turned off bypressing the remote control’s AV
MUTING button?
Video image dims.Is focus adjusted correctly?
Is distance too short or too long?
Color is poor or
unstable.
Are TRACKING and PHASE adjusted
correctly?
Is picture quality (color density, etc.)
adjusted correctly?
Is the correct broadcast system (color
system) selected?
Are signals (scanning frequency, etc.) to
connected devices appropriate?
Is the source setting correctly selected?
Is a wrong source (forced mode)
selected?
Corrective action

							Symptom
The upper part of the
video image bows or
distorts.
Video image and
audio sound suddenly
go out.
Remote control unit
does not work.Probable cause
While computer system signal is input,
isn’t a sync signal for composite sync
(C
S) or G on sync being input?
Isn’t signal with much jitter or skew
distortion being input to a video deck?
Is the source setting correctly selected?
Is a wrong source (forced mode)
selected?
Are video picture and audio turned off
by pressing the AV MUTING button on
the remote control unit?
Are batteries installed correctly?
Are batteries exhausted?
Is there a shielding object between the
remote control unit and the remote
sensor?

problem still persists, set it to the
correct dedicated source (forced
mode).
Turn on video picture and audio by

* This projector is equipped with a microcomputer that may operate abnormally due to interference from external components.
If this happens, turn off the main power and disconnect the power cord from the wall AC outlet. Then reconnect the power cord
to AC outlet and turn on the main power again.
(For the turning on and off the power, see pages 27 to 28.)
Maintenance
Stains on the cabinet
Should be wiped off with a soft cloth. If the cabinet is heavily stained, wipe it with a cloth soaked in water-diluted neutral
detergent and wrung well, then wipe clean with a dry cloth.
Since the cabinet may deteriorate in quality, become damaged or get its paint peeled off, be careful about the following:
Do not wipe it with a hard cloth.
Do not wipe it forcefully.
Do not wipe it with thinner or benzene.
Do not apply any volatile substance such as insecticides to it.
Do not allow any rubber or vinyl article to remain in contact with it for a long time.
Stains on the lens
Should be cleaned off with commercially available blowers or lens cleaning paper (for cleaning glasses and cameras).
Do not use liquid cleaning agents. This could cause the surface coating to be removed.
Do not rub or hit the lens as its surface is prone to damage.
