The display is "noisy"...
1. Display adjustment at your input source may be required. Adjust pixel tracking,
phase and filter. Noise is particularly common on YPbPr signals from a DVD
player. (If using a PC source, adjust using a high-frequency test pattern with one
pixel on/off throughout.)
2. The video input may not be terminated. Ensure the video input is terminated (75
). If it is the last connection in a loop-through chain, the video input should be
Ω
terminated at the last source input only.
3. The input signal and/or signal cables carrying the input signal may be of poor
quality.
4. If the distance between the input source device and the projector is greater than
25 feet, signal amplification/conditioning may be required.
5. If the source is a VCR or off-air broadcast, detail may be set too high.
For more information on lamp operation modes and auto-switching, refer to Section 3
– 3.7 The Lamp Menu.
1. The projector enforces a 60 second delay between powering down and up again,
because a hot lamp is more difficult to ignite. NOTE: It can take 2 minutes to
cool a lamp sufficiently enough before re-striking it.
1. It takes approximately 60 seconds for the projector to power up and strike a
lamp. One of the inherent properties of a UHP lamp is that it may not strike on
the first attempt. In this case, the projector will wait 30 seconds before striking
the lamp again. It will try a total of five times before it declares the lamp as
"Failed to Strike". Therefore it could take up to 2 minutes before light is seen on
the wall. You can check the status of either lamp in the projector by checking
in the Lamp Menu.
LAMP STATUS
2. Whenever replacing a lamp in a projector with a new lamp, remember to replace
the lamp card (PCB) also. This card contains key information about your lamp,
such as serial number, and factory default color primaries, which can, if not
installed, lead to incorrect lamp histories and difficulty of projector color
matching.
1. Ensure the Ethernet settings are valid for your site—all network devices should
have the same subnet mask and unique IP addresses.
2. Ensure to save any address change, and re-boot to implement.
3. If you still have trouble establishing communications with a projector added to an
existing Ethernet network, the projector's IP address is likely in conflict with
another address already in use. Contact your network administrator.
