ProblemCheck 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� (→ pages 13, 14)•	 Ensure	that	the	lamp	cover	is	installed	correctly.	(→ page 149)•	 Check	 to	see	 if	the	 projector	 has	overheated.	 If	there	 is	insufficient	 ventilation	around	the	projector	 or	if	the	 room	where you are presenting is particularly warm, move the projector to a c\
ooler location�•	 Check	 to	see	 if	you	 continue	 to	use	 the	projector	 for	another	 100	hours	 after	the	lamp	 has	reached	 the	end	 of	its	life� If so, replace the lamp� After replacing the lamp, reset the lamp hours used� (→ page 104)•	 The	lamp	may	fail	to	light.	Wait	a	full	minute	and	then	turn	on	the	power	again.•	 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� If this happens, wait a couple minutes and turn on the projector � (→ page 97) If you turn on the projector immediately after the lamp is turned off, the fans run without displaying an image for some time and then the projector will display the image� Wait for a moment�
Will turn off•	 Ensure	that	the	[OFF	TIMER]	or	[AUTO	POWER	OFF]	is	off.	(→ page 93, 100)
No picture
•	 Use	 the	COMPUTER1,	 the	COMPUTER2,	 the	VIDEO	 or	the	 S-VIDEO	 button	on	the	 remote	 control	to	select	 your	source (Computer, Video or S-Video)� (→ page 16) If there is still no picture, press the button again�•	 Ensure	your	cables	are	connected	properly.•	 Use	menus	to	adjust	the	brightness	and	contrast.	(→ page 85)•	 Ensure	that	the	lens	cover	is	open.	(→ page 5)•	 Reset	the	settings	or	adjustments	to	factory	preset	levels	using	the	[RESET]	in	the	Menu.	(→ page 104)•	 Enter	your	registered	keyword	if	the	Security	function	is	enabled.	(→ page 30)•	 Be	sure	to	connect	 the	projector	 and	notebook	 PC	while	 the	projector	 is	in	 standby	 mode	and	before	 turning	 on	the power to the notebook PC� In most cases the output signal from the notebook PC is not turned on unless connected to the projector before being powered up�* If the screen goes blank while using your remote control, it may be the result of the computer’s screen-saver or power management software�•	 See	also	the	next page�
Picture suddenly 
becomes dark•	 Check	 if	the	 projector	 is	in	 the	 Forced	 ECO	mode	 because	 of	too	 high	 ambient	 temperature.	 If	this	 is	the	 case,	lower the internal temperature of the projector by selecting [HIGH] for \
[FAN MODE]� (→ page 97)
Color tone or hue is 
unusual
•	 Check	if	an	appropriate	color	is	selected	in	[WALL	COLOR].	If	so,	select	an	appropriate	option.	(→ page 92)•	 Adjust	[HUE]	in	[PICTURE].	(→ page 85)
Image isn’t square to 
the screen
•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 17)•	 Use	the	Keystone	correction	function	to	correct	the	trapezoid	distortion.	(→ page 22)
Picture is blurred
•	 Adjust	the	focus.	(→ page 19)•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 17)•	 Ensure 	that 	the 	distance 	between 	the 	projector 	and 	screen 	is 	within 	the 	adjustment 	range 	of 	the 	lens. 
(→ page 130)
•	 Condensation	 may	form	 on	the	 lens	 if	the	 projector	 is	cold,	 brought	 into	a	warm	 place	and	is	then	 turned	 on.	Should this happen, let the projector stand until there is no condensati\
on on the lens�
Flicker appears on 
screen •	Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector 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 ALTI-TUDE] can cause the lamp to overcool, causing the image to flicker � Switch [FAN MODE] to [AUTO]� (→ page 9 7)
Image is scrolling 
vertically, horizontally 
or both•	 Check 	the 	computer’s 	resolution 	and 	frequency. 	Make 	sure 	that 	the 	resolution 	you 	are 	trying 	to 	display 	is 	supported	by the projector � (→ page 199)•	 Adjust	the	computer	image	manually	with	the	Horizontal/Vertical	in	the	[IMAGE	OPTIONS].	(→ page 87)
Remote control does 
not work
•	 Install	new	batteries.(→ page 9)•	 Make	sure	there	are	no	obstacles	between	you	and	the	projector.•	 Stand	within	22	feet	(7	m)	of	the	projector.	(→ page 9)
Indicator is lit or 
blinking
•	 See	the	POWER/STATUS/LAMP	Indicator.	(→ page 192)
Cross color in RGB 
mode
•	 Press	the	AUTO	ADJ.	button	on	the	projector	cabinet	or	the	remote	control.	(→ page 24)•	 Adjust	the	computer	image	manually	with	[CLOCK]/[PHASE]	in	[IMAGE	OPTIONS]	in	the	menu.	(→ page 86)
For	more	information	contact	your	dealer.

If there is no picture, or the picture is not displayed correctly.
•	 Power	on	process	for	the	projector	and	the	PC.
	 Be	sure	to	connect	 the	projector	 and	notebook	 PC	while	 the	projector	 is	in	 standby	 mode	and	before	 turning	 on	
the	power	to	the	notebook	PC.
	 In	most	cases	 the	output	 signal	from	the	notebook	 PC	is	not	 turned	 on	unless	 connected	 to	the	 projector	 before	
being	powered	up.
NOTE:	You	can	check	 the	horizontal	 frequency	of	the	 current	 signal	in	the	 projector’s	 menu	under	 Information.	 If	it	reads	 “0kHz”,	
this	means	there	is	no	signal	being	output	from	the	computer.	(→	page	102	or	go	to	next	step)
•	 Enabling	the	computer’s	external	display.
	 Displaying	 an	image	 on	the	 notebook	 PC’s	screen	 does	not	necessarily	 mean	it	outputs	 a	signal	 to	the	 projector. 	
When	using	a	PC	 compatible	 laptop,	a	combination	 of	function	 keys	will	enable/disable	 the	external	 display.	Usu-
ally,	 the	combination	 of	the	 “Fn” 	key	 along	 with	one	of	the	 12	function	 keys	gets	the	external	 display	to	come	 on	
or	off. 	For	 example,	 NEC	laptops	 use	Fn	+	F3,	 while	 Dell	laptops	 use	Fn	+	F8	 key	 combinations	 to	toggle	 through	
external	display	selections.
•	 Non-standard	signal	output	from	the	computer
	 If	the	output	 signal	from	a	notebook	 PC	is	not	 an	industry	 standard,	 the	projected	 image	may	not	be	displayed	
correctly. 	Should	 this	happen,	 deactivate	 the	notebook	 PC’s	LCD	screen	 when	the	projector	 display	is	in	 use. 	Each	
notebook	 PC	has	 a	different	 way	of	deactivate/reactivate	 the	local	 LCD	screens	 as	described	 in	the	 previous	 step.	
Refer	to	your	computer’s	documentation	for	detailed	information.
•	 Image	displayed	is	incorrect	when	using	a	Macintosh
	 When	 using	a	Macintosh	 with	the	projector,	 set	the	 DIPswitch	 of	the	 Mac	 adapter	 (not	supplied	 with	the	projector)	
according	to	your	resolution. 	After	setting,	restart	your	Macintosh	for	the	changes	to	take	affect.
	 For	setting	display	 modes	other	than	those	 supported	 by	your	 Macintosh	 and	the	projector,	 changing	the	DIP	 switch 	
on	a	Mac	 adapter	 may	bounce	 an	image	 slightly	 or	may	 display	 nothing. 	Should	 this	happen,	 set	the	 DIP	 switch	
to	the	 13"	 fixed	 mode	 and	then	 restart	 your	Macintosh. 	After	 that,	restore	 the	DIP	 switches	 to	a	displayable	 mode	
and	then	restart	the	Macintosh	again.
NOTE:	A	Video	 Adapter	 cable	manufactured	 by	Apple	 Computer	 is	needed	 for	a	PowerBook	 which	does	not	have	 a	mini	 D-Sub	
15-pin	connector.
•	 Mirroring	on	a	PowerBook
*	 When	 using	the	projector	 with	a	Macintosh	 PowerBook,	 output	may	not	be	set	 to	1024	 ×	768	 unless	 “mirroring” 	
is	off	on	your	PowerBook. 	Refer	to	owner’s	manual	supplied	with	your	Macintosh	computer	for	mirroring.
•	 Folders	or	icons	are	hidden	on	the	Macintosh	screen
	 Folders	or	icons	 may	not	be	seen	 on	the	 screen. 	Should	 this	happen,	 select	[View]	→	[Arrange]	 from	the	Apple	
menu	and	arrange	icons.
