Problem
Check These Items
Does not turn on or shut
down
• Check that the power cord is plugged in and that the power button on the projector cabinet or the remote control is on. See
pages
23
and
24
.
• Ensure that the lamp cover is installed correctly. See page
60
.
• Check to see if the projector has overheated or the lamp usage exceeds 2100* hours (up to 3100* hours : Quiet mode). See
page
60
. If there is insufficient ventilation around the projector or if the room where you’re presenting is particularly warm,
move the projector to a cooler location.
* LV-X7: 3100 hours (up to 4100 hours in Quiet mode).
• The lamp may fail to light. Wait a full minute and then turn on the power again.
• The lamp has reached the end of its usable life. Replace the lamp.
• When the lamp is turned off, the projector internal temperature is hot. If the power is turned on before the projector has
cooled down, the fan will run a short time before the lamp will turn on. If this happens, wait a couple minutes and turn on the
projector.
[LV-7365]
• Set [Fan mode] to [High altitude] when using the projector at altitudes approximately 5500 feet/1600 meters or higher. Using
the projector at altitudes approximately 5500 feet/1600 meters or higher without setting to [High altitude] can cause the
projector to overheat and the projector could shut down. Also the projector could not turn on due to the increased temperature
of the lamp after power off. If these happen, wait a couple minutes and turn on the projector.
[LV-7265/LV-7260/LV-X7]
• Select [High] in [Fan mode] if you use the projector at a high altitude or under low atmospheric pressure because LV-7265,
LV-7260, and LV-X7 do not have the [High altitude] option in [Fan mode]. Using the projector at a high altitude or under
low atmospheric pressure without setting to [High] can cause the projector to overheat and the projector could shut down.
Furthermore, the projector could not turn on due to the increased temperature of the lamp after power off. If these happen, wait
a couple minutes and turn on the projector.
Will turn off
• Ensure that the Power Management or Off timer is off. See page
51
,

.
No picture
• Use the INPUT button to select your source (LV-7365/LV-7265: Computer 1, Computer 2, Video or S-Video / LV-7260/LV-X7:
Computer, Video or S-Video). See page
26
. If there is still no picture, press the button again.
• Ensure your cables are connected properly.
• Use menus to adjust the brightness and contrast. See page
46
.
• Remove the lens cap.
• Reset the settings or adjustments to factory preset levels using the [Reset] in the Menu. See page
55
.
• Enter your registered Password if the Password function is enabled. See page
37
.
• When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the power to
the notebook PC. In most cases signal cannot be output from RGB output unless the notebook PC is turned on after connecting
with the projector.
* If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power man-
agement software.
• See also the next page.

pen, let the projector stand until there is no condensation on the lens.
Picture is distorted

.
Flicker appears on screen
• Set [Fan mode] to other mode than [High altitude] when using the LV-7365 at altitudes approximately 5500 feet/1600 meters or
lower. Using the projector at altitudes less than approximately 5500 feet/1600 meters and setting to [High altitude] can cause
the lamp to overcool, causing the image to flicker. Switch [Fan mode] to [Auto] or [High]. See page
52
.
Image is scrolling vertically,
horizontally or both
• Use the INPUT button to select your source (LV-7365/LV-7265: Computer 1, Computer 2, Video or S-Video / LV-7260/LV-X7:
