How to tell if the Lamp in your Projector or Rear Projection TV has Failed or is About to Fail
Here are 6 Basic Steps for Lamp Replacement.
lamp has two points on the bottom to grab the lamp for removal.
When the switch has been made, you can screw the new lamp housing unit into place and then re-attach the lamp access panel. Be sure to not over-tighten the screws. At this point, the users can reconnect the projector to the electrical outlet and turn on the project to see if the new lamp works. If the projector still does not work after the lamp replacement has been made, there may be a larger issue that is causing the problem. In this case, users should seek the help of professionals specializing in projector repair in order to determine the right course of action.

What is a Short Throw projector? I promise it’s not what you do when your lamp dies early..
Buying a new projector can be daunting. There are so many to pick from. Especially if you need a specific type like a Short throw. What is a short throw projector you ask and why might you need one?
Sometimes your space doesn’t allow for a standard distance from the screen. Many basements and home theaters allow the projector to be installed 10-20 foot back from the screen. Occasionally you need to mount the projector very close (less than 1-5foot back). The problem then becomes the image cannot be made large enough with the standard lens. This is where the short throw projector comes into play.
A short throw lens uses a special optical design that makes it easy to position the projector close to the screen without sacrificing image size. You will see this very often in schools.
When the schools use a Smartboard system, it relies entirely on short throw projectors such as the Smartboard UF55 which uses a 20-01032-20. This lamp with housing uses an original 215W Osram lamp, projecting 2000 lumens via the projectors short throw lens.
These models use the short throw lens design to allow a 100″ image from only 2 feet away. This allows the mounts to be very close to the screen. They both utilize a standard projector lamp, part # but allow a full sized image without sacrificing space.
This can be useful at home. You can use a smaller room and still enjoy movie theater-like image sizes. The Steelcase Polyvision PJ905 with a 2002031-20 lamp is a short throw projector that supports up to a 1080p input. There are other models that use short throw lenses as well. Picking the right projector will be a series in this blog by itself so I wont go into it here.
Using a short-throw projector at home can save you a lot of setup and configuration hassle. It opens up a lot of spaces that used to not be convenient for a projector. Even if you live in a narrow apartment, a short throw projector can work in as little as 10″ from the screen. Many projectors have a short throw lens as an option. That would manufacturer dependent. Buying a lens already installed is also an option.

There are a few things to check before contacting customer service that may rectify the situation.
Listen to the projector when you turn it on. You should hear the exhaust fans after you press the power button for at least a few minutes while the unit tries to start the lamp. If you do not hear the fans, it could be an indication that the lamp is not seated properly or the lamp access cover is not secure. Remove and re-install the lamp and carefully replace the lamp cover. If you still cannot hear any fans, check your power cord and then check to see if there are indicator lights flashing on the projector.
If you can hear the fans running and there is still no picture, check for any flashing/solid indicator lights on the projector. These lights are how the unit tells us what is going on within the projector, and has a corresponding reference in the owner’s manual.
Every projector has an owner’s manual available on line for free. Check the flashing indicator lights against the description in the owner’s manual. If the description points to a failed lamp, please contact our Customer Service for further assistance.
Most Projectors have a Lamp Hour Counter or Lamp Timer to keep track of lamp usage. The units are designed to warn you when the lamp is approaching the end of its life. When a new lamp is installed, you must manually reset the timer or the projector will not know the lamp has been changed and will count an incorrect amount of hours. This also means that if you prematurely reset the timer, you will not have a proper hour count on the replacement lamp once installed. Some projectors will turn off completely and need to be manually reset before they will turn on if the lamp hours are exceeded beyond the factory settings.
– It is always a good idea to check the manual and reset the timer as instructed.
Check to make sure the bulb is installed flush with the front of the housing. It should sit exactly as the old bulb and must be installed the same way or the light will not illuminate the image correctly. Should the bulb be slightly off center, or not aligned correctly the image can be dim, and you will need to contact PurelandSupply for a Return Authorization (RA) Form.
My projector turns on for a few minutes and turns off after installing the new lamp.
While this could be a defective lamp, it is common for many Projectors to turn themselves off when there is another issue. Many times the fans will be dusty and not spin correctly. That will cause the projector to shut down. Try cleaning the projector with a vacuum to make sure as much dust and dirt is cleaned up as possible.
Anytime you replace your lamp, it is a good idea to clean the unit for dust. Heat is the primary cause of early lamp failure. By keeping your TV/Projector clear of dust, you will help it keep the lamp at a proper temperature. While the lamp is out, use a vacuum cleaner to collect any dust from the lamp compartment and the vents so that it does not re-collect in the TV/Projector.
This is recommended to be done at least when the lamp is changed, but once every 3-4 months is even better. With proper maintenance of the TV/Projector, the longer it will last.
It is very rare that there can be multiple lamps for a Projector. Occasionally the manufacturer will switch lamps mid production, which can be confusing and frustrating. This can be resolved very easily with some help from you. Record any numbers on the lamp/bulb. Also verify your model # as well as any letters before or after the model number. Contact our customer service with the information from your old lamp/bulb and we can correct your order and have the issue taken care of.
Our lamps only project a bright white light. Your Projector processes the color control by shining the white light thought either a color wheel for DLP or LCD panels for LCD units. The color can only be affected by the internal optics of the projector. Generally an off color display will not be noticed with an older lamp as it is not operating at full power. With a new lamp, it will be brighter and show any issues that may have been there previously with a lot more clarity. A new lamp will NOT resolve this as the issue is with the internal optics.
