- High Temperature: The lamp operates at very high temperatures. Allow the television to cool down completely (at least 30 minutes) before handling the lamp.

- Ventilation: Ensure proper ventilation around your television to prevent overheating, which can shorten lamp life.

4. Setup (Lamp Installation)
Follow these steps to safely replace the lamp in your Mitsubishi DLP Television:
- Power Off and Unplug: Turn off your television and unplug it from the wall outlet. Allow the TV to cool down for at least 30 minutes to prevent burns from the hot lamp.
- Locate Lamp Access Panel: The lamp access panel is typically located on the back or side of your television. Consult your television's owner's manual for the exact location.
- Remove Access Panel: Use a screwdriver (if necessary) to remove the screws securing the lamp access panel. Carefully remove the panel.
- Disconnect Old Lamp: The old lamp module will have a handle or a pull tab. Gently pull the handle to slide the old lamp module out of its compartment. Some models may require disconnecting a power connector first.
- Remove Old Lamp: Once disconnected, carefully remove the old lamp module from the television. Dispose of the old lamp according to local environmental regulations, especially due to mercury content.
- Insert New Lamp: Align the new Aurabeam replacement lamp module with the lamp compartment. Slide it firmly into place until it clicks or seats securely. Ensure any power connectors are properly reattached if they were disconnected.
- Replace Access Panel: Reattach the lamp access panel and secure it with the screws.
- Plug In and Power On: Plug your television back into the wall outlet and power it on.
- Reset Lamp Timer: Most DLP televisions have a lamp timer that needs to be reset after a lamp replacement. Refer to your television's owner's manual for specific instructions on how to reset the lamp timer through the TV's menu system. This step is crucial for accurate lamp life monitoring.

5. Operating Instructions
Once installed, the Aurabeam replacement lamp operates automatically with your television. No special operating procedures are required for the lamp itself.
- Initial Warm-up: The lamp may take a few moments to reach full brightness after the television is turned on. This is normal.
- Power Cycles: Avoid frequent on/off cycles, as this can reduce the lifespan of the lamp.
6. Maintenance
Proper maintenance can help extend the life of your lamp and television:
- Clean Ventilation: Regularly clean the ventilation grilles and filters of your television to ensure proper airflow. Blocked vents can lead to overheating and premature lamp failure.
- Dust Removal: Use a soft, dry cloth to gently wipe dust from the exterior of the television. Do not use abrasive cleaners or solvents.
- Lamp Replacement: Replace the lamp when the picture becomes dim, colors appear faded, or the television displays a lamp warning indicator.

7. Troubleshooting
If you encounter issues after installing your new lamp, consider the following:
- No Picture / TV Not Turning On:
- Ensure the television is securely plugged into a working power outlet.
- Verify the lamp module is fully seated and all connectors are properly attached.
- Check if the lamp access panel is securely closed, as some TVs have safety switches that prevent operation if the panel is open.
- Dim Picture / Poor Color:
- Confirm the lamp timer was reset after installation. An un-reset timer might indicate an old lamp.
- Check TV picture settings.
- Ensure TV ventilation is not blocked.
- Lamp Indicator Light On:
- This usually indicates the lamp needs replacement or the lamp timer needs to be reset. If it's a new lamp, reset the timer.
- If the light persists after resetting the timer, re-check the lamp installation.
If troubleshooting steps do not resolve the issue, consult your television's owner's manual or contact Aurabeam customer support.
