Solution
The projector does not turn 
on after initial installation. 
• The VX-33i is not plugged
in or the AC outlet is not 
active. 
• Ensure that the VX-33i is
plugged in and that the AC 
outlet is active. 
The projector is on, but there 
is no video image on-screen. 
• Incorrect source selection. 
• Source component is not 
turned on.
• Select the correct source. 
• Turn on the source. 
A projected image from a 
DVD is split or otherwise 
scrambled. 
• DVD player is set to
progressive scan mode.
• Turn off progressive scan
on the DVD player.
Image is too bright and/or 
lacks definition in the bright 
areas of the image. 
• Contrast is set too high.
• Lower the contrast setting.
Image appears “washed out” 
and/or dark areas appear too 
bright. 
• Brightness is set too high.

setting.
Colors in the image are 
swapped; for example, reds 
appear blue or vice versa. 
• The Red/Pr, Green/Y or
Blue/Pb outputs from the 
source are connected to 
the wrong inputs on the 
VX-33i. 
• Ensure that the source
outputs are connected to 
the correct input. 
Image geometry is incorrect.

selection.

down, or the image disap-
pears during operation. 
• The projector will not turn
