Common Problems & Solutions
(→	“POWER/STATUS/LIGHT	 Indicator”	 on 	 page 	168,	169.)
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 	altitudes 	approximately 	760 	m/2500 	feet 	or 	higher . 	Using the projector at altitudes approximately 760 m/2500 feet or higher without setting to [HIGH] 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 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 24)
Will turn off
•	 Ensure	that	the	[OFF	TIMER],	[AUTO	POWER	OFF]	or	[PROGRAM	TIMER]	is	off.	(→ page 100, 115)
No picture
•	 Check	if 	the 	appropriate 	input 	is 	selected. 	(→ page 16) 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 76)•	 Check	that	the	SHUTTER	(lens	shutter)	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 116)•	 Enter	your	registered	keyword	if	the	Security	function	is	enabled.	(→ page 35)•	 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	172�
Picture suddenly 
becomes dark•	 Check	if	the 	projector 	is 	in 	the 	For ced 	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 	[W ALL 	COLOR]. 	If 	so, 	select 	an 	appropriate 	option. 	(→ page 
97)
•	 Adjust	[HUE]	in	[PICTURE].	(→ page 77)
Image isn’t square to 
the screen
•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 18)•	 Use	the	Keystone	correction	function	to	correct	the	trapezoid	distortion.	(→ page 32)
Picture is blurred
•	 Adjust	the	focus.	(→ page 21)•	 Reposition	the	projector	to	improve	its	angle	to	the	screen.	(→ page 18)•	 Ensure	that 	the 	distance 	between 	the 	projector 	and 	screen 	is 	within 	the 	adjustment 	range 	of 	the 	lens. 
(→ page 153)
•	 Has	the	lens	been	shifted	by	an	amount	exceeding	the	guaranteed	range?	(→ page 156)•	 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�
Image is scrolling 
vertically, horizontally 
or both•	 Check	the	computer’ s 	resolution 	and 	frequency . 	Make 	sure 	that 	the 	resolution 	you 	are 	tr ying 	to 	display 	is 	supported by the projector� (→ page 159)•	 Adjust	the	computer	image	manually	with	the	Horizontal/Vertical	in	the	[IMAGE	OPTIONS].	(→ page 79)

Remote control does 
not work•	 Install	new	batteries.	(→ page 10)•	 Make	sure	there	are	no	obstacles	between	you	and	the	projector.•	 Stand	within	22	feet	(7	m)	of	the	projector.	(→ page 11)
Indicator is lit or 
blinking
•	 See	the	POWER/STATUS/LIGHT	Indicator.	(→ page 168, 169)
Cross color in RGB

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 	standb y 	mode 	and 	bef ore 	tur ning 	on 	
the	power	to	the	notebook	PC.
	 In	most	cases 	the 	output 	signal 	from 	the 	notebook 	PC 	is 	not 	tur ned 	on 	unless 	connected 	to 	the 	projector 	bef ore 	
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 117	or	go	to	next	step)
•	 Enabling	the	computer’s	external	display.
	 Displaying	an	image 	on 	the 	notebook 	PC’ s 	screen 	does 	not 	necessar ily 	mean 	it 	outputs 	a 	signal 	to 	the 	projector .	
When	using	a 	PC 	compatib le 	laptop , 	a 	combination 	of 	function 	k eys 	will 	enab le/disable 	the 	e xternal 	displa y.	Usu-
ally,	the	combination 	of 	the 	“Fn”	k ey 	along 	with 	one 	of 	the 	12 	function 	k eys 	gets 	the 	e xternal 	displa y 	to 	come 	on 	
or	off.	For	example, 	NEC 	laptops 	use 	Fn 	+ 	F3, 	while 	Dell 	laptops 	use 	Fn 	+ 	F8 	k ey 	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 	industr y 	standard, 	the 	projected 	image 	ma y 	not 	be 	displa yed 	
correctly.	Should	this 	happen, 	deactiv ate 	the 	notebook 	PC’ s 	LCD 	screen 	when 	the 	projector 	displa y 	is 	in 	use .	Each 	
notebook	PC	has 	a 	diff erent 	w ay 	of 	deactiv ate/reactivate 	the 	local 	LCD 	screens 	as 	descr ibed 	in 	the 	pre vious 	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 	DIPs witch 	of 	the 	Mac 	adapter 	(not 	supplied 	with 	the 	projector) 	ac-
cording	to	your	resolution.	After 	 setting, 	 restart 	 your 	 Mac 	 for 	 the 	 changes 	 to 	 take 	 affect.
	 For	setting	displa y 	modes 	other 	than 	those 	suppor ted 	b y 	y our 	Mac 	and 	the 	projector , 	changing 	the 	DIP 	s witch 	on 	
a	Mac	adapter 	ma y 	bounce 	an 	image 	slightly 	or 	ma y 	displa y 	nothing.	Should 	this 	happen, 	set 	the 	DIP 	s witch 	to 	
the	13"	fixed 	mode 	and 	then 	restar t 	y our 	Mac.	After 	that, 	restore 	the 	DIP 	s witches 	to 	a 	displa yable 	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 	ma y 	not 	be 	set 	to 	1024 	× 	768 	unless 	“mirror ing”	is 	off 	on 	y our 	
MacBook.	Refer 	 to 	 owner’s 	 manual 	 supplied 	 with 	 your 	 Mac 	 computer 	 for 	 mirroring.
•	 Folders	or	icons	are	hidden	on	the	Mac	screen
	 Folders	or	icons 	ma y 	not 	be 	seen 	on 	the 	screen.	Should 	this 	happen, 	select 	[Vie w] 	→	[Arrange]	from 	the 	Apple 	
menu	and	arrange	icons.
