Re: sharp projection tv lamp replacement

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.

Turns on, great sound no picture!

They use a lamp (specialized bulb) a little like a movie or film projector. Since this is a glorified light bulb (much brighter) it has a filament which (you guessed it) burns out. It needs to be replaced. Google your make and model TV and include the words "lamp replacement".

It seems as though my Sony HD tv's picture has gotten darker over the few weeks. Does the bulb need to be repalced?

IF it is over two years since it was replaced, this is the way that they fail---get darker just before they fail completely.

Average life span is 2,000 hours which works out to for most people about 2 years.

Google the model number with the word Lamp after it and you will find dozens of places to purchase a replacement---the lamp is meant to be a customer replaceable part.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

My rca dlp doesn't turn on

You probably need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

TV doesn't have the colour red... just blue and green

This site has a manual that may specify the type of lamp. The manual costs something, with no guarantee you'll find what you want.
Select brand "Pioneer" and enter the model "SDP5795W" then click Find; on the next page click on the model number SDP5795W to go through to the page that lists the manuals. One is a service/repair manual that I expect would have information about the lamp or bulbs.

The TV is more than 10 years old, and with "planned obsolescence" it may be hard to even get lamps now. All the very best of luck.

All rear projection TVs has a lamp thats like a special bulb inside the TV.

The TV is warning you that this is about to go and will need to be replaced.

This is not a serious problem as TV lamps goes after certains hours of use (normally 4,000 hours sometimes more) and the TV manual should have instructions on how to do this and the part you need.

Contact Sharp support if your TV is still in warranty and for further help :

if this helps please vote ...thanks and good luck!
