Over-Temperature	Protection
If	the	temperature	inside	the	projector	rises	too	high,	the	over-temperature	protector	will	automatically	turn	off	the	lamp	
with	the	STATUS	indicator	blinking	(2-cycle	On	and	Off.)
Should	this	happen,	do	the	following:
•	 Unplug	the	power	cord	after	the	cooling	fans	stop.
•	 Move	the	projector	to	a	cooler	location	if	the	room	where	you	are	presenting	is	particularly	too	warm.
•	 Clean	the	vents	if	they	are	clogged	with	dust.
•	 Wait	about	60	minutes	until	the	inside	of	the	projector	becomes	cool	enough.

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 118)•	 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 t\
o a cooler 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 116)•	 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/1700	meters or higher� Using the projector at altitudes approximately 5500 feet/1700 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 65) If you turn on the projector immediately after the lamp is turned off, t\
he 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 59, 68)
No picture
•	 Use	the	COMPUTER1,	HDMI1/MHL, HDMI2, VIDEO, USB-B, or APPS button on the remote control to select your source (COMPUTER, HDMI1/MHL, HDMI2, VIDEO, USB-B, or APPS)� (→ 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 52)•	 Reset	the	settings	or	adjustments	to	factory	preset	levels	using	the	[RESET]	in	the	Menu.	(→ page 74)•	 Enter	your	registered	keyword	if	the	Security	function	is	enabled.	(→ page 35)•	 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 un\
less 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 65)
Color tone or hue is 
unusual
•	 Check	if	an	appropriate	color	is	selected	in	[WALL	COLOR].	If	so,	select	an	appropriate	option.	(→ page 
59)
•	 Adjust	[HUE]	in	[PICTURE].	(→ page 52)
Image isn’t square to 
the screen
•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 17, 18)•	 Use	the	Keystone	correction	function	to	correct	the	trapezoid	distortion.	(→ page 21)
Picture is blurred
•	 Adjust	the	focus.	(→ page 18)•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 17, 18)•	 Ensure	that	the	distance	between	the	projector	and	screen	is	within	the	adjustment	range	of	the	projection	window� (→ page 75)•	 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 condensat\
ion 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/1700 meters or lower� Using the 
projector at altitudes less than approximately 5500 feet/1700 meters and setting to [HIGH ALTITUDE] can cause the lamp to overcool, causing the image to flicker� Switch [F AN MODE] to [AUTO]� (→  page 65)
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 131)•	 Adjust	the	computer	image	manually	with	the	Horizontal/Vertical	in	the	[IMAGE	OPTIONS].	(→ page 54)

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	71	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/disab le	the	exter nal	display .	Usually,	
the	combination	of	the	“Fn”	key	along	with	one	of	the	12	function	ke ys	gets	the	exter nal	display	to	come	on	or	off.	
For	example,	NEC	laptops	use	Fn	+	F3,	while	Dell	laptops	use	Fn	+	F8	key	combinations	to	toggle	through	exter nal	
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	display ed	
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/reactiv ate	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	Mac
	 When	using	a	Mac	with	the	projector,	set	the	DIPswitch	of	the	Mac	adapter	(not	supplied	with	the	projector)	accord-
ing	to	your	resolution.	After	setting,	restart	y our	Mac	f or	the	changes	to	tak e	aff ect.
	 For	setting	display	modes	other	than	those	supported	by	your	Mac	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	Mac.	After	that,	restore	the	DIP	switches	to	a	display able	mode	and	then	
restart	the	Mac	again.
NOTE:	A	Video	Adapter	cable	manufactured	by	Apple	Inc.	is	needed	for	a	MacBook	which	does	not	have	a	mini	D-Sub	15-pin	terminal.
•	 Mirroring	on	a	MacBook
*	 When	using	the	projector	with	a	MacBook,	output	may	not	be	set	to	1024	×	768	unless	“mirroring”	is	off	on	your	
MacBook.	Refer	to	o wner’s	man ual	supplied	with	y our	Mac	computer	f or	mirror ing.
•	 Folders	or	icons	are	hidden	on	the	Mac	screen
	 Folders	or	icons	may	not	be	seen	on	the	screen.	Should	this	happen,	select	[View]	→	[Arrange]	from	the	Apple	
menu	and	arrange	icons.
