Rear Projection Televisions are not like other televisions that can run maintenance-free for 20 years or more. They need to have their lamps changed on occasion, and most have air filters that need to be cleaned every month or two. Lamps typically last about 8,000 hours on most models high end models, some of the cheaper models last only 1,000-2,000 hours. Keep in mind however that some lamps won't make it all the way to their estimated life spans. If you operate your LCD or DLP TV in a warm environment that is not adequately ventilated, or at higher elevations, this can reduce lamp life. Failing to keep the air filter clean may reduce lamp life as well. And some lamps will just fail sooner than others--estimating average lamp life is not an exact science and testing methods vary greatly among manufacturers.
ere is a checklist of what to do to get the most out of your lamp:

  1. Check out the presets and select the setting with the lowest light output.
  2. Once you've done that adjust the brightness down to your liking. The lower the brightness the long the lamp will last.
  3. Check and clean the air filters on a monthly basis. Having a clean air filters means that your lamp has better airflow. Air is what is used to cool the lamp and the cooler your lamp runs the longer it will last.
Each owner's manual for a rear projection TV comes with instructions on how to replace the lamp. Here are the typical steps for replacing a lamp.
  1. Turn your TV off. Let it sit there for about 5 minutes to let the cooling fan help cool the lamp.
  2. Unplug your TV from the power let it sit about another 30 minutes. Even with the TV turned off power is still going to the lamp and the lamp receptacle can still be hot enough to burn you. Even if you think that the lamp is cool I recommend that you do not touch the receptacle.
  3. Usually the lamp has a cover that you will need to unscrew. Most manufactures use a Philips head screw for holding the cover shut. Unscrew the lamp cover.
  4. Unpackage the replacement lamp. Be careful not to tough the glass, as oil from your fingers can damage the lamp's surface.
  5. Pull the lamp out. Most lamps have a plastic tab or hoop on the handle that you can use to pull it out. Follow the owners manual for specific instructions on how to pull the lamp out. Make sure you do not touch the surrounding lamp housing if you just turned off the TV. It can burn you if it is hot.
  6. After the lamp has cooled, place it into the empty box of the replacement lamp. Never put the used lamp into a plastic bag.
  7. Using the guiding post also called "gutters" by some manufactures slide the lamp replacement lamp in pushing it until you hear a firm click.
  8. Screw the lamp cover back in.

I need to replace the bulb in my Sharp XV-S55U projector. The manual does not show how to change bulb. I can find the part on the internet but not the "how to".


Hi There If you want we are able to supply lamps as we ship internationally and also the same with our ICE Digital Daytime projection screens. This lamp however is now getting difficult to source so you might want to consider selling it whilst at least it is working.
