Common Problems & Solutions
(→	“POWER/STATUS/LIGHT/TEMP./SHUTTER/KEY	LOCK	Indicator”	on	page	175,	176.)
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)•	 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.•	 The	light	module	may	fail	to	light.	Wait	a	full	minute	and	then	turn	on	the	power	again.•	 Set	[FAN	MODE]	to	[HIGH]	when	using	the	projector	at	highlands.	Using	the	projector	at	highlands	can	cause the projector to overheat and the projector could shut down. If th\
is happens, wait a couple minutes 
and turn on the projector. (→ page 104)
 If you turn on the projector immediately after the light module is turne\
d off, the fans run without displaying an image for some time and then the projector will display the image. Wait for a moment.•	 In	case	it’s	hard	to	think	the	trouble	is	not	caused	on	the	above	mentioned	conditions,	unplug	the	power	cord from the outlet. Then wait 5 minutes before plugging it in again. (\
→ page 26)
Will turn off
•	 Ensure	that	the	[OFF	TIMER],	[AUTO	POWER	OFF]	or	[PROGRAM	TIMER]	is	off.	(→ page 108, 123)
No picture
•	 Check	if	the	appropriate	input	is	selected.	(→ page 18) If there is still no picture, press the SOURCE button 
or one of the source buttons again.
•	 Ensure	your	cables	are	connected	properly.•	 Use	menus	to	adjust	the	brightness	and	contrast.	(→ page 82)•	 Is	the	[POWER	ON	SHUTTER]	in	the	on-screen	menu	set	to	[CLOSE]?•	 Check	that	the	SHUTTER	(lens	shutter),	the	LIGHT	SOURCE,	or	AV	MUTE	(image	off)	buttons	are	not	pressed.•	 Reset	the	settings	or	adjustments	to	factory	preset	levels	using	the	[RESET]	in	the	Menu.	(→ page 124)•	 Enter	your	registered	keyword	if	the	Security	function	is	enabled.	(→ page 37)•	 If	the	HDMI	IN	or	the	DisplayPort	IN	signal	cannot	be	displayed,	try	the	following.- Reinstall your driver for the graphics card built in your computer, or use the updated driver . For reinstalling or updating your driver, refer to the user guide accompanied with your computer or graphics card, or contact the support center for your computer manufactu\
rer. Install the updated driver or OS on your own responsibility. We are not liable for any trouble and failure caused by this installation\
.•	 Signals	may	not	be	supported	depending	on	the	HDBaseT	transmission	device.	IR	and	RS232C	cannot	be	used in certain cases as well.•	 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	page	179.
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 104)
Color tone or hue is 
unusual
•	 Check	if	an	appropriate	color	is	selected	in	[WALL	COLOR].	If	so,	select	an	appropriate	option.	(→ page 
104)
•	 Adjust	[HUE]	in	[PICTURE].	(→ page 83)
Image isn’t square to 
the screen
•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 20)•	 Use	the	Keystone	correction	function	to	correct	the	trapezoid	distortion.	(→ page 34)
Picture is blurred
•	 Adjust	the	focus.	(→ page 24)•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 20)•	 Ensure	that	the	distance	between	the	projector	and	screen	is	within	the	adjustment	range	of	the	lens. 
(→ page 156)
•	 Has	the	lens	been	shifted	by	an	amount	exceeding	the	guaranteed	range?	(→ page 158)•	 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 conden\
sation on the lens.
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 161)•	 Adjust	the	computer	image	manually	with	the	Horizontal/Vertical	in	the	[IMAGE	OPTIONS].	(→ page 85)

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 125	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 .	Usu-
ally,	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	
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	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)	ac-
cording	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	Computer	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.
