Problems with the Image or Sound❑An image does not appear on the screen.
Check that the power light is on and the lens cover is off.
Also make sure the cables are installed correctly, as
described in Chapter 1.
The correct image source may not be selected. Press the
Source button on the remote control or the operation
panel to choose another image source.
❑Only part of the computer image is displayed.
If the computer’s output resolution setting is higher than
1024 × 768, the projector resizes the image. If the
computer output is not compatible with this resizing,
choose a different display setting on the computer. In
Windows 3.x, use Windows Setup in the Main program
group. For a Macintosh, choose Operation Panels under
the Apple menu and then choose Monitors. In the
Monitors screen, choose Options and make sure Macintosh
Hi-Res Display or another 1024 × 768 display is selected.
For supported display settings, see “Supported Monitor
Displays (EMP-7550/7500)” on page 65 or “Supported
Monitor Displays (EMP-5550/5500)” on page 66.
You also may need to modify existing presentation files if
you created them for a different resolution. See your
software manual for specific information.
❑The message NO SIGNAL is displayed.
An image source not connected to the projector is selected,
the signal is not being output from the computer, or the
signal is not reaching the projector. Make sure the
connectors are securely attached to both the projector and
the image source. Then check that the image source is
selected correctly. When NO SIGNAL is displayed, you
cannot access the source (computer/video) menu.
