Remove and Replace the Ballast/Power Supply ECA
The ballast/power supply ECA (520-0114-xx) fastens to the chassis. It converts 100-240 VAC supply voltage to various low voltage DC levels required internally by the projector. The power supply directly interfaces with the ballast to control lamp strike and operation. The ballast steps up voltage from the power supply to ignite the lamp module. The ballast/power supply ECA also interfaces with the controller ECA to provide DC power and exchange control signals. Audio amplification and takes place on the ballast/power supply ECA. Fuses on the ballast/power supply ECA protect against internal shorts or supply surges. The fuses are not available as FRU parts as a blown fuse usually indicates circuit damage and the need for ECA replacement. 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. 1. Remove the following items: Lamp module (page 42) Focus ring (page 30) Zoom ring (page 30) Front bezel (page 32) Rear bezel (page 49) Top case (page 52) 2. Detach the lamp cable connector from the side of the lamphouse. Squeeze the two tabs on the side of the connector and slide it rearward through the retainer on the lamphouse.

CAUTION Avoid touching or damaging the color wheel. 5. Lift the optical engine away from the projector. 6. Place the engine on a soft, static-free surface or in an ESD-protected container.

Controller ECA Functions A Pixelworks PW164B processor is responsible for control of the entire system as well as processing of the graphics and video data, including GUI insertion and rescaling to the DMDs native SVGA resolution. The processor consists of an Intel 80C186 core CPU with on-chip peripherals including GPIO, Timers, UART, IR receiver logic, interrupt controller, and a 16-bit memory interface. The PW164B also includes video input and graphic input ports, a synchronization decoder and automatic image optimizer. The image data is processed and fed to an on-board frame buffer. The data is then scaled and the on-screen display information is laid over the image. The processor also supports color lookup-tables, color-space expansion, and keystone correction. The processor outputs all timing and image data required for the TI DLP driver logic. The processor's internal vertical and horizontal image scaler is bypassed; a Faroudja FLI2200 deinterlacer performs scaling. A voltage-controlled amplifier controls audio volume and balance. System Memory The Pixelworks processor is interfaced to a single 8Mbit word-wide FLASH memory for code storage, and a 32kbit serial EEPROM for unit-specific and dynamic data storage. The FLASH is attached to the PW164Bs word-wide memory interface. An EEPROM is also located on the DMD board. This EEPROM stores DMD and engine-specific data.

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.

Remote Control Features and Functions Presenter Remote The Presenter Remote is a hand held remote control device that can be used with the X1 and other InFocus projectors. It consists of an electronic circuit board including a microcontroller with embedded firmware, IR interface, batteries, an elastomeric keypad and plastic case. A green status LED lights when the user presses any key. The laser button controls an FDA Class II laser pointing device. Function keys are the complete set of matrix keys minus the laser key. Function key communication takes place with the projector via IR. The remote will go into sleep mode immediately after each operation. The remote will also go into sleep mode when any key except the laser key is held down continuously for more than one minute. To wake from sleep mode, a discrete key press of any key is required. If the laser key is held down continuously for more than 2 minutes, the laser will power off. To reactivate the laser after accidental timeout, the laser key must be released and pressed again. The remote uses two AAA alkaline batteries which are included. The battery life with typical use is about 6 months. Conductor and Conductor+ Remotes The Conductor+ is the same as the Conductor except for the addition of a laser pointer. The projector ships with the Conductor remote. Operational information for the Presenter remote above also applies to the Conductor and Conductor+. Depressing the backlight button on the side of the remote activates the backlight. The backlight remains active for 10 seconds or until the backlight button is depressed again, whichever comes first. If any key on the keypad is depressed while the backlight is active, the backlight will go out during the period of the key press and reactivate when the key is released. The 10 second timer resets at the time of the key press.
Prepare for Power Up with Top Case Removed
You can remove the top case and power up the projector to check fan or thermal switch operation. You also do this to check internal voltages and signals, which may require additional projector disassembly. Here's how to prepare the projector for power up with the top case removed. 1. Remove the top case (page 52) NOTE The lamp must be in place and connected to start the projector with the top case removed. 2. Use vinyl electrical tape or other non-conductive means to hold the safety switch actuator in the depressed (closed) position.

3. Do one of the following: Check controller ECA voltages and signals (page 81) Check the thermal switch (page 86) Check the color wheel cable (page 84) Check the fans (page 87) Check the ballast/power supply ECA voltages and signals (page 88) Check the I/O ECA voltages and signals (page 90)
Check Controller Voltages
To check voltages, you need to power up the projector with the top case removed. See page 80 for instructions on how to do this. Check Controller ECA Voltages and Signals 1. Prepare to power up the projector with the top case removed. (page 80) 2. Remove the chassis. (page 12) 3. Position the ballast/power supply ECA near enough to the projector to connect the controller/power supply cable from the controller ECA. You can do this if you turn the ballast/power supply ECA over and connect it to the controller ECA in an upside-down position. This also leaves you room to access the controller ECA with measurement probes.
4. Connect the lamp to the lamp cable connector at the side of the lamphouse. Make sure the connector fully engages the connector on the lamp module.
5. Position the top case right side up at the rear of the projector. 6. Extend the keypad cable from the rear of the projector and plug it into the keypad connector on the top case.
7. Connect the projector to AC power. 8. Power up the projector, and check the voltages using the illustration on the next page. 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 controller ECA for voltages and signals.
Check the Color Wheel and Reseat the Cable
If the color wheel cable is not properly seated in its connector, the color wheel will not start when the projector powers up. When the color wheel does not spin, there is no lamp enable signal, and the lamp will not strike. Normally, you hear the brief high-pitched sound when the color wheel spins up to speed. If you don't hear the sound, or if you are not sure, you can do a visual check to confirm the color wheel operation. If the color wheel does not spin, the first item to check is the color wheel ribbon cable connection and reseat it if necessary. The cable seats at connectors on the color wheel and the controller ECA. To check color wheel operation and reseat the cable, do the following: 1. Power up the projector with the top off. (page 80) NOTE The lamp must be in place and you must close the safety switch to start the projector with the top case removed. 2. Examine the color wheel to see if it is spinning. The color wheel is located between the lamphouse and the optical engine.
