Resets all adjustment values of
MENU/ items on the PICTURE quality
menu to the factory-set status
ENTER (adjustment values: 0, text mode: NORMAL).
There is a relationship between the adjustment of items R-GAIN, G-GAIN,
and B-GAIN and that of item CONTRAST. For example, when adjustment
values are : R-GAIN: 0, G-GAIN: 5, B-GAIN: 0, and CONTRAST: 0, changing
CONTRAST to 1 changes the adjustment values as follows: R-GAIN: 1, G-
GAIN: 6, and B-GAIN: 1.
Also, when the adjustment value of any of R-GAIN, G-GAIN, and B-GAIN has reached -30 (minimum) or +30 (maximum), CONTRAST cannot be
adjusted to any higher value. For example, when R-GAIN is 0, G-GAIN is 5,
B-GAIN is 0, and CONTRAST is 0, increasing CONTRAST allows the other
adjustment values to increase until R-GAIN: 25, G-GAIN: 30, and B-GAIN:
25, then CONTRAST becomes 25 and cannot be adjusted to any higher
value.

Depending on the signal from a device connected, adjustment may be needed
after a dedicated source is set. If that is the case, adjust the appropriateitems.
When the input mode (SOURCE) is VIDEO or Y/C, and if AUTO is set, the
automatic detecting function may work, possibly causing the screen to be
intermitted or disturbed. In that case, set to a dedicated source (forced mode).
When special effect playback (fast-forward/ twice-speed/triple-speed) is performed on a video deck, etc, the picture may be disturbed or intermitted,
depending on the device.

							Replacing the Light-Source Lamp
The light-source lamp has its service life. It is approximately 1000 hours.
When the light-source lamp approaches the end of its service life, its degradation progresses rapidly. When the lamp’\
s used
hours exceed 900 hours, the projector’s LAMP indicator comes on. Also, at the start of projection (lamp energized),\
 the message
“REPL.-LAMP” appears on the projection screen for about two minutes. Then, replace with a new light-source lamp, o\
r arrange
for a replacement lamp. When lamp’s service has reached 1000 hours, the projector’s LAMP indicator starts blinking\
, and if you
press the OPERATE button (or press the remote control’s OPERATE button for more than one second), the light-source \
lamp
does not turn on. The specified lamp replacement period is 1000 hours, but depending on use conditions, the replacement
period may vary. If video image is dark and its color tint is extraordinary even after you have adjusted color tint and \
brightn ess,
replace the light-source lamp a little earlier.
Purchase new light-source lamps (part No. : ET-LA995) from the Panasonic-authorized dealer where you have purchased th\
e
projector, or consult the nearest Panasonic Service center.
If the projector is set up in a tight place which is unsuitable for work, and if you perform replacement work there, thi\
s could hurt
you. Move the projector to a place wide enough for work, and then replace the lamp.
Use a genuine product for the light-source lamp. If you use other than a genuine product, this could cause a malfunction\
. Also,
never use an old light-source lamp. An old lamp could cause marked degradation in performance or explode itself, possibl\
y
causing the projector to malfunction. Also, its broken pieces could come out of the projector and harm you when replacin\
g the
light-source lamp.
Do not replace the light-source lamp immediately after the projector has been used. The temperature of the light-source \
lamp
is still high and could cause a burn. Be sure to allow a cooling period of one hour or more before performing replacemen\
t work.
Before starting lamp replacement work, turn off the MAIN POWER switch (see page 28), and disconnect the power cord fro\
m
the wall outlet. If you perform the replacement work with the power cord left connected, this could cause harm or electr\
ic
shock.
Never discard an old light-source lamp (used lamp), as is. Otherwise, this could involve a great danger. The lamp cont\
ains a
xenon gas inside, which is applying a high pressure. If the gas is not removed, it could cause the lamp to explode.
For handling used lamps, refer to the manual supplied with the new replacement lamp you have purchased.
Remove the lamp-replacement
opening cover by loosening
screws.
Loosen the two screws with a flat-end screwdriver.
The screws are fitted so that they do not come off the lamp-
replacement opening cover.
