The display is "noisy"...
'
1. Display adjustment may be required. Adjust pixel tracking, phase and filter.
Noise is typical of YPbPr signals from a DVD player.
2. The video input may not be terminated. Make sure the video input is terminated
S
(75 ). If it is the last connection in a loop-through chain, the video input should
be terminated at the last projector only.
3. The signal cables carrying the input signal may be of poor quality. Use only good
quality signal cables.
4. The distance between the input source device and the projector may be too great.
If the distance between the input source device and the projector is greater than
25 feet, signal amplification/conditioning may be required.
5. The input signal may be of poor quality.
6. If the source is a VCR or off-air broadcast, detail may be set too high. Keep near

1. The vertical offset is too severe, causing the moveable internal component to
block access to the screw. Decrease the vertical offset to move the component up
and out of the way. NOTE: If your projector has a motorized lens mount and
cannot power-up due to an expired lamp or power supply problem, the motorized
functions must be disabled and then vertical offset adjusted manually. Contact
your dealer or the manufacturer.
