How to Replace Mitsubishi Rear Projection HDTV Lamps

by Michael J. Scott

Mitsubishi rear projection televisions (RPTVs) use a lamp to display the image on the screen. Unfortunately, the lamp will burn out over time and need to be replaced. While you can call a repair service to do it for you, Mitsubishi makes it so users can replace the lamps on their RPTVs. All you need is a screwdriver and a little time and your TV will be up and running.

Unplug your TV from the electrical outlet. Disconnect any A/V components you have connected to the TV. Wait an hour for the TV to completely cool down before replacing the lamp.

Find the lamp cover. Depending on your Mitsubishi TV, the lamp cover may be in either the back or the front of the TV. If it's in the back, look for a plastic panel, near the bottom of the set, held in place by a few screws. It's typically on the left side of the back panel. If it's in the front it will be behind the speaker grill. Pull both sides of the grill toward you and the grill will detach from the TV. The cover will be near the left speaker.

Remove the screws holding the lamp cover in place and remove the cover. This will reveal the lamp.

Remove any screws holding the lamp assembly in place. Newer lamps use captive screws that can't be removed. If that is the case with your set, simply loosen the screws. Grab the lamp assembly and slide it out of the lamp compartment.

Slide the replacement lamp into the lamp compartment. Either tighten the captive screws or replace the removed screws. Be careful not to touch the glass on the bulb as you are sliding the lamp in place. Replace the lamp cover and the speaker grill if you removed it. Reconnect all of your A/V equipment and plug your TV back in.

Turn on the TV. Press "Menu" on your remote. Scroll to "Settings" and scroll down to "Lamp Reminder." This will reset the lamp reminder to zero.
