resolved, the Signal out of Range message displays. When the projector leaves the Setting Up Image state, the logo no longer displays; this would include a change to either Display state or Menu state. Display This is the projector's primary mode of operation and the one the user spends the most time in. The LED is steady green and the projector displays an image from the selected source. If the source is lost, the projector goes to the Search State. Menu The user interacts with the projector through configuration of on-screen menus. The menus are rendered in an overlay memory that becomes visible on top of the current image during menu mode. The Menu state provides access to parameters not accessible directly through the keypad. The Menu state can be executed from the Zoom state, Search state, Setting Up Image state, Screen Saver state, or Display state. The Menu state can be enabled or disabled via the infrared remote (except the Executive remote) or projector keypad. The LED remains steady green. Power save When more than 20 minutes has elapsed since a source was locked or a key was pressed, and Power Save is enabled, the lamp is extinguishes and a one-minute cool-down period begins. If a source is detected or the Power key is pressed during the cool-down period, the projector will not react immediately but switches to the Startup state at the end of the cool-down period. The LED slow flashes green during cool-down. At the end of cool-down, the LED changes to a slow blip green and the projector enters the Power Save state. The Power Save state lasts for 10 minutes. If there is no activity during this 10 minutes, the projector switches to the Off state. If a source is detected or the IR remote power key is pressed or any key on the projector keypad is pressed during this 10 minutes, the projector immediately switches to Startup state. Screen save When more than the preset time has elapsed since a source was locked or a key was pressed, and Power Save is not enabled, the projector switches to a black screen that prevents damage to the DMD. The projector remains in the Screen Save state until a key is pressed, a source is detected, or the projector is shut down. The projector will respond to any key by switching from Screen Save to the Search mode. Note that key-presses are not processed other than to exit Screen Save mode. The LED flashes a slow blip green. Screen Save is always enabled, except when Power Save is enabled. Power down confirm The LED lights solid green and the projector displays a blank curtain screen. Only the Power key is active. If it is not pressed in less than 3 seconds, power down is cancelled. The projector displays the message Powering down. Press Power to confirm.
Cool down The lamp cool-down state provides 1 minute of cooling time, beginning when the lamp is extinguished, before the lamp can be re-struck. The fans continue to run during this time. All projector control is disabled for of the 1-minute cool-down period. The LED changes to slow flashing green during cool-down.
3. If the color wheel is not spinning, check the ribbon cable connection. The ribbon cable inserts into a connector at the color wheel motor.
Ensure that the cable is fully seated in the connector. Then power up the projector again and recheck color wheel operation. 4. If the color wheel still does not spin, remove the chassis (page 12) to gain access to the color wheel cable connection on the controller ECA. 5. Check and reseat the color wheel cable at the controller ECA.
. To reseat the cable, pull it out of the connector on the controller ECA. Re-insert the cable fully, making sure it seats all the way into the connector.
Check the Thermal Switch
The thermal switch is designed to open when the temperature inside the projector gets too high. When the switch opens, the power supply shuts down, turning the projector off. When the projector shuts down after operating for a few minutes or when the lamp fails to strike after repeated attempts at startup, check the thermal switch. First, power up the projector with the top off (page 80). Let the projector run until it shuts down. Measure resistance across the terminals at the thermal switch. If the resistance is infinite (), replace the lamphouse, which includes the thermal switch.
Go to remove and replace the lamphouse. (page 45)
Check fan operation
You can visually check the operation of the fans to see if they both work properly. Check the fans if the projector exhibits symptoms of overheating or if the red status LED indicates that a thermal issue is present. To check the fans, first prepare for projector power up with the top case removed (page 80). Then follow these steps: 1. Connect the projector to AC power. 2. Power up the projector. CAUTION When you start the projector, there is voltage present on the controller ECA and power supply. Be very careful where you probe and where you touch. 3. Follow the directions below to check the fans. The fans should both start up when you press the power button.
If a fan fails to operate, check the voltage at the connector on the controller ECA (page 81) to verify that the fan is receiving power. Or unplug the fan cable from the controller ECA and substitute a known good fan. If a fan has failed, remove the fan and replace it (page 27).
Check Ballast/Power Supply Voltages and Signals
To check voltages and signals on the controller ECA, first prepare for projector power up with the top case removed. Then follow these steps: 1. Position the top case right side up at the rear of the projector. 2. Extend the keypad cable from the rear of the projector and plug it into the keypad connector on the top case.
3. Connect the projector to AC power. 4. Power up the projector. CAUTION When you start the projector, there is voltage present on the controller ECA and power supply. Be very careful where you probe and where you touch.
5. Use measurement equipment to check the ballast/power supply ECA for voltages and signals. DANGER Do not attempt to measure the output voltage from the ballast when the lamp strikes. High voltage produced by the ballast to strike the lamp can ruin test instruments as well as cause personal injury.
Check I/O ECA Voltages and Signals
1. Prepare for projector power up with the top case removed. (page 80) 2. Remove the chassis. (page 12) 3. Position the ballast/power supply ECA in or near enough to the projector to connect the controller/power supply cable from the controller ECA. Be sure that there is enough space above the I/O ECA to allow use of measurement probes.
7. Connect the projector to AC power. 8. Power up the projector. CAUTION When you start the projector, there is voltage present on the controller ECA and power supply. Be very careful where you probe and where you touch.
9. Use measurement equipment to check the I/O ECA for voltages and signals.
