See pages 22 and 23 . • Ensure that the lamp cover is installed correctly. See page 54 . • Check to see if the projector has overheated or the lamp usage exceeds 2\ 100 hours (up to 3100 hours : Eco mode). If there is insufficient ventilation around the projector or if the room where you’re presenting is par- ticularly warm, move the projector to a cooler location. • 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. • Ensure that the Power Management is off. See page 48 . • Use the VIDEO, the S-VIDEO or the COMPUTER button (the SOURCE button on\ VT570/VT47) on the remote control to select your source (Computer, Video or S-Video). See page 25 . 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 41 . • Remove the lens cap. • Reset the settings or adjustments to factory preset levels using the “Default” in the Menu. See page 50 . • Enter your registered keyword if the Security function is enabled. See p\ age 45 . • 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 f\ rom 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 computers screen- saver or power management software. • See also the next page. • When one of the following happens, the Lamp mode automatically changes f\ rom Normal to Eco. *When there are no signals (blue or black screen) → To r eturn to the Normal mode, select another available source. * When the image is muted using the PIC-MUTE button on the remote control \ → Press the PIC-MUTE button again to return to the Normal mode. * When the room where you re presenting is particularly warm → Move the projector to a cooler location. • Check if an appropriate color is selected in Wall Color. If so, select an appropriate option. See page 40 . • Adjust Hue in Picture. See page 41 . • Reposition the projector to improve its angle to the screen. See page 27 . • Use the Keystone correction function to correct the trapezoid distortion\ . See page 29 . • Adjust the focus. See page 28 . • Reposition the projector to improve its angle to the screen. See page 27 . • Ensure that the distance between the projector and screen is within the \ adjustment range of the lens. See pages 13 for VT670/VT570/VT470 and 14 for VT47. • 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. • Use the SOURCE button on the projector cabinet or the VIDEO, the S-VIDEO\ or the COMPUTER button (the SOURCE button on VT570/VT47) on the remote control to select your source (Video, S-Video or Computer). See page 25 . • Adjust the computer image manually with the Horizontal/Vertical in the “Advanced → Page 2”. See page 48 . • Install new batteries. VT670/VT470: AAA 2. See page 10 . VT570/VT47: Lithium coin cell (CR2032). See page 12 . • Make sure there are no obstacles between you and the projector. • Stand within 22 feet (7 m) of the projector. pages 10 for VT670/VT470 and 12 for VT570/VT47. • See the POWER/STATUS/LAMP Indicator on page 56 . • Press the AUTO ADJUST button on the projector cabinet or the AUTO ADJ. b\ utton on the remote control. See page 31 . • When “Off” is selected in Auto Adjust, adjust the computer image m\ anually with Clock/Phase in “Advanced → Page 2” in the menu. See page 48 .

58 7. Appendix 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 RGB cable between the projector and the computer before turning on the computer. There are some notebook PCs, which do not output signal unless there is a projector or monitor conn\ ected first. 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. See page 49 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 projec- tor. When using a PC compatible laptop, a combination of function keys will enable/disable the external display. Usually, 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 projec- tor) 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 noth\ ing. Should this happen, set the DIP s witch 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 x 768 unless “mirror- ing” 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.
