Replacing a Microsoft Surface Lamp Assembly

If the display brightness of your Microsoft Surface unit diminishes, or if the display is completely dark even after the unit is turned on, you might need to change the lamp assembly. To verify that you need to change the lamp assembly, follow the troubleshooting steps in Troubleshooting Display Issues.

You can also use the Microsoft Surface Lamp Timer tool to help you track how long a lamp has been used. The tool includes a timer that you can reset when you install a new lamp, and the tool flashes orange lights in the ends of the tabletop if the lamp is not lighting. For more information, see the KB 975564 article.

At a high level, after you receive the new lamp assembly from Microsoft, you should remove the old lamp assembly, insert the new lamp assembly, and dispose of the current lamp assembly.

ImportantImportant
To complete these steps, you will need a #2 Phillips screwdriver.

Removing the Current Lamp Assembly

CautionCaution
The lamp assembly can be extremely hot

To reduce the risk of injury caused by excessive heat, always allow sufficient time for the lamp assembly to cool down after the Microsoft Surface unit has been turned off. A minimum waiting period of 15 minutes is needed. Ensure safe heat conditions before you remove the assembly.

To remove the current lamp assembly

  1. If the Microsoft Surface unit is on, turn it off.

  2. Unplug the Microsoft Surface unit and wait for approximately 15 minutes for the system and lamp assembly to cool down.

  3. If the Microsoft Surface unit has acrylic panels, remove the panel to expose the I/O connections.

    For more information, see Removing the End Panel to Expose the I/O Connections.

  4. Locate the lamp access door (labeled 1 in the following illustration), and then remove the two thumb screws on the right side of the door (labeled 2 in the following illustration) by turning them counterclockwise by using a Phillips screwdriver.

  5. Remove the lamp access door by swinging it open from the right side and then pulling the door away from the tabs on the left side.

    You can now access the base of the lamp assembly.

    WarningWarning
    There is an interlock switch that is connected to the two screws on the lamp access door. If you open the door while the Microsoft Surface unit is still plugged in and turned on, this switch stops power to the lamp assembly. This switch is for your safety. Do not disable this interlock. Disabling the interlock switch will increase the risk of serious injury or death from electric shock or fire, or damage to the Microsoft Surface unit.

  6. On the base of the lamp assembly, loosen the two thumbscrews by turning them counterclockwise.

  7. Grip the finger holes on the base of the lamp assembly, and then slowly pull it out of the Microsoft Surface unit. Be careful not to touch the sides of the lamp assembly because it might be hot.

    CautionCaution
    To reduce the risk of injury caused by excessive heat, be careful not to touch the sides of the lamp assembly because it might be hot.

    CautionCaution
    If the old lamp assembly is broken, take the following precautions when you are removing the assembly.

    • Ventilate the area where the breakage occurred, and avoid inhaling any dust or particulates.

    • Use cut and puncture resistant gloves when you are working with broken glass.

    • Do not remove glass shards with a standard vacuum cleaner. Instead, use sticky tape to collect any small glass fragments and powder.

    • Wipe the area clean with damp paper towel or disposable wet wipes.

    • Place the lamp assembly and any soiled cleaning material in a closed container to be recycled appropriately.

    • Wash your hands thoroughly before eating, smoking, handling tobacco products, applying cosmetics, or using the restroom.

  8. Set the old lamp assembly to the side and do not throw it away. Instead, dispose of the old lamp assembly by sending it back to Microsoft or by completing the directions in the Disposing of the Old Lamp Assembly section.

Inserting a New Lamp Assembly

  1. Carefully remove the new lamp assembly from its box. Save the box so you can use it to send the old lamp assembly back to Microsoft for proper disposal.

    CautionCaution
    Be careful to not touch the bulb of the lamp assembly because doing so might cause it to burn-out prematurely.

    WarningWarning
    This lamp can cause serious skin burn and eye inflammation from shortwave ultraviolet radiation if the outer envelope of the lamp is broken or punctured. Do not use where people will remain for more than a few minutes unless adequate shielding or other safety precautions are used.

  2. Hold the lamp assembly so that the base of the lamp assembly is facing toward you, the text on the base is upside down, and the black power connector is on the upper-left side of the metal siding of the lamp assembly.

  3. Slowly slide the new lamp assembly through the opening that you removed the old lamp assembly from.

    CautionCaution
    The lamp assembly fits only one way into the Microsoft Surface unit. Do not force the lamp assembly if it is not fitting into the unit. Forcing the lamp assembly might damage the lamp assembly or the Microsoft Surface unit.

  4. On the base of the lamp assembly, use your fingers to tighten the two thumbscrews by turning them clockwise. Do not use a screwdriver because over-tightening the screws might permanently damage the unit.

  5. Insert the lamp access door into the tabs on the left side of the opening, and then swing the door to the right to close it.

  6. On the right side of the lamp access door, insert the two screws by turning them clockwise by using a Phillips screwdriver.

    Do not over tighten the screws.

  7. Plug in the Microsoft Surface unit, turn it on, and verify that the lamp assembly is now working and that the display on the Microsoft Surface unit is working correctly.

    If the display is still not working correctly, contact Microsoft Surface Support for additional assistance.

  8. If the Microsoft Surface unit has acrylic panels, add the panel to cover the I/O connections.

    For more information, see Removing the End Panel to Expose the I/O Connections.
