How to Replace a Bulb in a Mitsubishi DLP TV

Digital light processing (DLP) televisions provide stunning high-definition images and require little maintenance over their lifetime. However, about every 3,000 to 6,000 hours of use, the DLP bulb will need to be replaced. While this may cause the technologically challenged among us to fret, the replacement procedure is simple, fast and easy enough for a novice to accomplish successfully.

Step

Unplug your television and put on your clean latex gloves. These should be your first steps before handling the bulb, to prevent both electrical shock and component damage from skin oils.

Step

Remove the DLP lamp assembly from your TV. While each model is a bit different they will almost always be found on the back left-hand side of the television and will only have one or two clearly visible Phillips screws holding them in place. After removing the screws, the lamp assembly will dislodge from its connectors and come out with a gentle pull.

Step

Use your flat head screw driver to pry the lamp and ballast from the protective enclosure. In most cases, there will not be any screws holding the protective enclosure in place. In some cases, the lamp assemblies only comprise the ballast and the bulb.

Step

Take your Phillips head screw driver and remove the ballast wires from the bulb. You may run into some variation here, depending on your model of Mitsubishi TV. In some cases, the second ballast wire is held in place by a nut on the back end of the bulb. If this is the case in your lamp assembly, use the pliers to remove the nut.

Step

Remove the three or four (depending on your model) Philips head screws that are affixing the face of the bulb to the ballast. Remove the bulb from the ballast.

Step

Place your new DLP bulb in the ballast and replace the previously removed screws. Make sure that the screws are tight.

Step

Reconnect the two ballast wires to their proper spots on the new bulb. Make sure all connections are tight.

Step

Put the protective enclosure back on the DLP lamp assembly (if applicable to your lamp model). Make sure that it snaps flush into place.

Step

Return the lamp assembly to its proper spot in your DLP television. It is important to make sure that when pushing it back into place that the external connectors that link it to the TV and provide the lamp with electricity are snug. In most cases, the lamp will have the female end of the connector.

Step

Replace the screws that hold the lamp assembly in place inside the TV and snap the TV's lamp cover back in place.
