Nothing is projected on the screen. What should I do?
Try the following:
- Check that the Power light is green, not flashing, and the lens cover is removed. Also press the A/V Mute button on the remote control to see if the picture was turned off temporarily.
- If the projector doesn’t turn on, the Control Panel Lock may be enabled. Use the remote control or press and hold the Enter button on the projector for 7 seconds to release the lock.
- The projector may be in standby or sleep mode. If the projector has not received any signal for 30 minutes, it turns off the lamp to conserve the lamp life and save energy. If the Power light is orange, press the Power button to turn on the projector.
The attached computer may also be in sleep mode or displaying a black screen saver. Try pressing a key on the computer.
- If the power was switched off and then on again, wait until the Power light stops flashing and remains orange. Then press the Power button again.
- Check the Video Signal, Computer1 Input, or Computer2 Input setting in the Signal menu to make sure it is correct for the selected source. See Adjusting the Input Signal.
- Make sure your equipment is not plugged into the Monitor Out port.
- Messages may have been turned off in the Display setting of the Extended menu. See Selecting Projector Setup Options.
- Adjust the Brightness setting on the Image menu (see Adjusting Colors and Clarity) or select High for the Brightness Control setting in the Settings menu (see Customizing Projector Features).
- Make sure your video equipment is turned on.
- With Direct Power On enabled in the Operation setting of the Extended menu, if you unplug the projector and then plug it right back in, you must press the Power button to turn on the projector.
- Make sure at least one of the projector’s remote receivers are turned on in the Settings menu. See Customizing Projector Features.
- If you’ve connected a laptop computer, make sure it’s set to display on an external monitor.
If you’re using a PC notebook:
- Press the function key that lets you display on an external monitor. It’s often labeled with an icon such as , but it may also be labeled CRT/LCD. You may have to hold down the Fn key while pressing it. Check your laptop’s manual or online help.
On most systems, the key lets you toggle between the LCD screen and the projector, or display on both at the same time. Allow a few seconds for the projector to sync up after pressing it.
If that doesn’t work, press the ? Help button on the projector for a list of laptop brand-specific button combinations you can press to switch to an external display.
- If the function key doesn’t let you display simultaneously on both screens, you might need to use the Display utility in the Windows Control Panel to make sure that both the LCD screen and external monitor port are enabled. From the Windows Control Panel, open the Display utility. In the Display Properties dialog box, click the Settings tab, then click Advanced. The method for adjusting the setting varies from computer to computer; you may need to click a Monitor tab, then make sure the external Monitor port is set as your primary display or enabled. See your computer manual or online help for details.
If you’re using Macintosh OS X:
- Select System Preferences from the Apple menu and click Displays.
- Click Detect Displays.
- To display the entire desktop on both your projector screen and LCD screen, click the Arrangement or Arrange tab. (If you don’t see this tab, make sure it isn’t hidden by another window.)
- Click Mirror Displays in the lower corner of the screen. One of the monitor icons automatically moves on top of the other.
