45 FIGURE 39 In sta ll ing the Ken si ngton l ock Troubleshooting If you’re experiencing trouble with the projector, follow these steps to make sure everything is properly connected before you call Customer Service for assistance. 1Check cable connections. Verify that all computer, CableWiz- ard and power cables are properly connected. 2Verify that all power is switched on. 3Verify that the projector has not been switched off with the st an db y button on the remote or keypad . 4If the projector still doesn’t display an image, restart the com- puter. NOTE: Macin tosh computers req uire a s peci fic power-up sequence: the proj ector must b e turned on before you turn on th e computer. 5If the problem still exists, unplug the projector from the com- puter and check the computer monitor’s display. The maxi- mum resolution the 610 can display is 800x600 pixels, preferably 640x480; the maximum resolution the 620 can dis- play is 1024x768 pixels, preferably 800x600. The problem might be with the graphics controller in your computer rather than with the projector. When you reconnect the projector, remember to turn the computer and monitor off before you power up the projector. Power the equipment back up in this order: projector, monitor, computer.
46 Maintenance & Troubleshooting 6If you’re using a laptop computer and its monitor is not dis- playing your presentation, make sure you have re-activated the computer’s monitor. Most laptop computers de-activate their own monitor when a second display device, such as a projector, is connected. Refer to page 55 for more information. 7If the problem still exists, read through the problems and solutions in this chapter. If you call Customer Service for assistance: •Find out what kind of graphics controller card is installed in your computer. The projector is connected to this circuit board in the computer. Most PCs use a VGA or SVGA graphics con- troller. Solutions to Common Problems Problem: Nothin g on projection scr een • Make sure that the power cord is properly connected to a func- tional AC electrical outlet. Make sure that the power cord is properly connected to the projector. •If the projector is plugged into a power strip, make sure the power strip is turned on. •Make sure the projector is switched on. •Make sure the projector’s lamp is securely connected. See “Replacing the Projection Lamp” on page 41. •Make sure that the CableWizard and the cables do not have any bent pins.
