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. Make sure the video input is terminated
(75
Ω
). If it is the last connection in a loop-through chain, the video input should
be 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.
1. If the lamp won’t ignite, there may be an interlock failure such as an open lamp
door, or failed lamp fan. An error code will display on the status LED display
located on the built in keypad.
2. If a temperature is too high (e.g.“DMD over critical temp limit”), the lamp will
not ignite until the temperature is low enough. Cool the projector and try again.
3. For suspected communication failures, power-down the projector and try again.
4. If the lamp does not ignite after a second and third try, replace the lamp.
1. Try increasing the lamp power.
2. The DMDs may be overheated.
3. Replace the lamp.
1. Increase lamp power, if possible.
2. Replace the lamp.
1. Make sure “Intensity” is selected in the Lamp menu. Other lamp modes disable
LiteLOC
.
2. If the lamp power has increased to its maximum in order to maintain a LiteLOC
setting, LiteLOC
is automatically terminated. If the values shown in the Lamp
menu indicate that the lamp power has reached this “over-drive” state, either
reduce your LiteLOC
setting or install a new lamp.
1. Make sure the Ethernet settings are valid for your site—all network devices
should have the same subnet mask and unique IP addresses.
2. Make sure to save any address change, and re-boot to implement.
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.
