of the Video source device.
2. Connect the other end of the S-Video cable to the

„If the selected video image is not displayed after the projector is 
turned on and the correct video source has been selected, check that 
the Video source device is turned on and operating correctly. Also 
check that the signal cables have been connected correctly.
„If you have already made a Component Video connection between 
the projector and this S-Video source device using Component Video 
connections, you need not connect to this device using an S-Video 
connection as this makes an unnecessary second connection of 
poorer picture quality. See “Connecting Video source devices” on 
page 19 for details.
