How to Replace a Bulb in a Mitsubishi DLP TV

By Omar Saad

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.

Things You'll Need

  • Latex gloves
  • Phillips screwdriver
  • Flat had screwdriver
  • Pliers
  • Replacement DLP bulb

Step 1

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 2

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 3

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 4

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 5

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 6

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

Step 7

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

Step 8

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 9

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 10

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

Tips & Warnings

  • Make sure that your TV has been off for at least an hour, allowing it to cool down before changing the bulb.Make sure that the TV is unplugged before changing the bulb to avoid electric shock.To prolong the life of your new DLP bulb, make sure that the display setting on your TV is not on "dynamic," which is commonly referred to as the showroom setting.
  • Failing to wear clean latex gloves when changing out a lamp can cause skin oils to come in contact with the new bulb. This can drastically reduce its life.If the lamp assembly is not pushed back into place and reconnected snugly to the TV, electrical arcing may occur, which will cause the new bulb to burn out quickly.
