3. Setup and Installation

WARNING: Installation of this component requires technical expertise and should only be performed by qualified service personnel. Attempting installation without proper knowledge may result in damage to the projector or personal injury due to high voltage components and delicate optics.

Follow these general steps for installation. Always refer to the specific service manual for your BenQ i950L projector for detailed instructions.

1. Safety First: Ensure the projector is completely powered off and disconnected from the main power supply. Allow sufficient time for the projector to cool down.
2. Access Projector Interior: Carefully open the projector casing according to the BenQ i950L service manual (not provided here). Note the location and orientation of the existing color wheel.
3. Disconnect Old Color Wheel: Gently disconnect the ribbon cable and any mounting screws securing the old color wheel. Handle the component by its edges to avoid touching optical surfaces.
4. Install New Color Wheel: Position the new color wheel (as shown in Figure 1 and Figure 2) into the designated slot. Ensure it is correctly aligned. Secure it with the appropriate screws.
5. Connect Ribbon Cable: Carefully connect the ribbon cable from the projector's main board to the connector on the new color wheel's circuit board (visible in Figure 2). Ensure a firm and correct connection.
6. Reassemble Projector: Once the new color wheel is securely installed and connected, carefully reassemble the projector casing. Ensure all screws are tightened and no cables are pinched.
7. Initial Test: Reconnect the projector to power and turn it on. Observe for proper operation, correct color display, and absence of unusual noises. If any issues arise, power off immediately and re-check installation steps or consult a professional.

4. Operation

The color wheel is an internal component that operates automatically as part of the BenQ i950L laser projector's optical system. Once correctly installed, no user intervention is required for its operation. The projector's internal software and hardware manage the color wheel's rotation and synchronization to produce the desired image colors.

5. Maintenance

The color wheel itself is a sealed unit and does not require direct user maintenance. To ensure its longevity and optimal performance, it is recommended to:

• Keep the projector's air filters clean to prevent dust accumulation within the optical path, which could affect the color wheel.
• Operate the projector within its specified environmental conditions (temperature, humidity) to prevent stress on internal components.
• Avoid physical shocks or vibrations to the projector, which could damage delicate internal parts.

6. Troubleshooting

If you experience issues after installing the new color wheel, consider the following:

• No Image / Projector Error: Double-check all cable connections, especially the ribbon cable to the color wheel. Ensure the color wheel is seated correctly and not obstructed.
• Incorrect Colors / Color Distortion: This could indicate an issue with the color wheel's synchronization or damage during installation. Power off the projector, disconnect, and carefully re-inspect the color wheel and its connections.
• Unusual Noise: A grinding or high-pitched noise from within the projector after installation may indicate the color wheel is not properly mounted, is rubbing against another component, or has a faulty motor. Immediately power off the projector and investigate.

If troubleshooting steps do not resolve the issue, it is highly recommended to seek assistance from a professional projector repair technician.

7. User Tips

• Due to the delicate nature of projector components, always wear anti-static gloves when handling the color wheel and other internal parts to prevent damage from static discharge or fingerprints.
• Keep the work area clean and dust-free during installation to prevent contaminants from entering the projector's optical system.
• Before fully reassembling the projector, perform a brief power-on test to confirm basic functionality of the new color wheel.
