Is My Lamp Failing?

How to tell if the Lamp in your Projector or Rear Projection TV has Failed or is About to Fail

Most problems on these TV's are due to lamp problems.  For brand-specific help, just click the appropriate link for your Hitachi, JVC, Mitsubishi, Sony, or Toshiba TV.

Projector lamps from Pureland Supply are only used in Projectors or TVs that use LCD, DLP, D-ILA and LCoS (Liquid Crystal on Silicon) display chips. These utilize patented Short Arc technology utilized by Philips, Ushio, Phoenix and Osram.

Projector lamps can easily be replaced by a customer commonly needing nothing more than a screwdriver.  If a special tool is required, it comes packaged with the new lamp.  We stock all popular projection lamps for sale for all brands with Original Bulbs Inside.  There are no replaceable lamps in flat panel TV's (plasma, LCD, and LED TV's), traditional direct view TV's, and the old floor-standing CRT rear projection TV's.

An On Screen Menu is a pattern of text on the screen that the TV generates internally, like the TV menu you get by using the TV remote.  This is the volume display, channel display, input display, etc. If you can see an ON SCREEN MENU, the lamp is not bad.

Usually, a dead lamp can be confirmed by looking at it.  Each lamp contains a thin glass tube.  If this tube is shattered or has a hole melted in it, then it is bad.  Often, people watching the set when the lamp fails will hear a "pop."  A lamp with a crack, blister, or discoloration in the glass tube (down the center) may also indicate failure. 

Occasionally, a lamp will go bad with no visible internal damage.  This can only be confirmed by substituting a good lamp.  Using an Ohm meter or multi-meter won’t work here as these lamps use Short Arc technology.

When a lamp fails to light, the lamp power supply may make a buzzing or sparking noise caused by the excess high voltage being bled off.  On sets that restart several times, this buzzing may be heard on each restart.  This noise is also an indication of a bad lamp.

Bad lamps usually fail to light when the set is powered on, but weak lamps can also blank out while the set is running.  The set may detect this and attempt to restart the lamp.  If the picture and On Screen Menu  go out intermittently, the lamp is the likely culprit.

Here are some common Failure Modes by manufacturer. Your issue may not be listed here specifically but most of these can apply to multiple models/manufacturers. 

Call our well-trained staff at 1-800-664-6671 or email us at or if you are not sure if you need a lamp.

TV starts up with a dark screen, no picture, and no On Screen Menu .  After a few minutes, the LAMP light on the front of the set stays on constantly.

TV starts up with a dark screen, no picture, and no On Screen Menu .  After a few minutes, the blue and orange lights on the front panel blink simultaneously and continuously twice per second.

Failure Mode 1:  Projector starts up, attempts to light the lamp. Possibly hearing the ballast 'tick' as it tried to light. Then the Status and power light turn red and the unit shuts down.

Failure Mode 2: (Some models) TV works, but the LAMP lights lights a constant yellow/amber.  This is a warning that the lamp has been used for a certain number of hours and may fail soon.  When you replace the lamp, an on-screen message will ask you to reset the lamp timer, so this warning light turns off.  This must be done using the original TV remote. Set top box remote may not work.

Failure Mode 3: (Some models) Picture flashes, flickers, and/or changes color.  After a few minutes, the set may shutdown.  This may be due to a copy lamp being used.  Make sure the bulb in your lamp is made by Osram of Philips. No-name lamps may cause this issue.

Failure Mode 4:  No fans start when power is pressed. Only the status and power LED flash back and forth.  This indicates the lamp timer as run out and put the unit in protection mode. Refer the manual for proper reset, however most units are reset by holding down the Left and Right directional arrows and Power button on the projector simultaneously for a few seconds to force a timer reset. 

Failure Mode 1: Status Indicator will flash Six times before pausing and then continuing to flash until power is removed. The lamp indicator will also flash on and off until power is removed.

Failure Mode 2: Status light will be off and the lamp indicator will light solid red indicting the lamp has run past 2100 hours and is now in protection mode. This must be reset using the factory remote.  by pressing Help and holding it for about 10 seconds until the Lamp indicator turns off.

Failure Mode 1:  The green POWER light flashes once per second (the normal start-up indication), but the screen is dark with no picture and no On Screen Menu .  The set tries to restart 3 more times, and then the red LAMP light starts blinking.
Failure Mode 2:  The set works OK, but the screen goes dark with no picture or On Screen Menu .  After a few minutes, the picture comes back on by itself but continues to go on and off by itself.  The green POWER light blinks continuously while the picture is out, and there may or may not be sound.
Failure Mode 3:  The set works, but a lamp warning message appears on the screen each time it is turned on. 

Failure Mode 1:  Lamp will remain lit but display a message “Lamp Failure” before shutting down.

Failure Mode 2: No image at all, and the Red lamp indictor will be lit.
Some models will warn you of imminent failure as the lamp nears its 2000-hour life limit.

Failure Mode 1: Lamp Indicator will flash red with standby indicator steady red.

Failure Mode 2: Lamp indicator will be lit steadily as will the power indicator. 

Failure Mode for TVs.  The red light on the front panel comes on constant, and the green light blinks 3 times per second (the normal start-up indication), but the screen is dark with no picture and no On Screen Menu .  The set shuts down and resets itself 8 times.  Then, the green and red lights blink simultaneously and continuously once per second.

Upon start up the fans will run for a few minutes. You will hear the color wheel spin up and the ballast attempting to start. This will repeat three times until the unit confirms the lamp failure. At that point the indicator for the lamp(s) will flash red instead of green. Some models will flash six times before pausing and then flashing again until the power is removed.

6 Steps to Change Your Projector Lamp

Here are 6 Basic Steps for Lamp Replacement. 

You should always refer to the owners manual for the proper specific steps but if you have a pretty basic Projector or Rear Projection TV, these steps should get you back up and running.

    1. Preparing the Projector to Be Opened
Before attempting to open the projector, users should turn off and unplug the device. They should also allow the device to cool down. It could take anywhere from 30 to 45 minutes for the projector to cool down completely. Then remove any dust on the outside casing with a soft, dry, and clean cloth. This will ensure that dust does not enter into the machine and get onto the vulnerable interior parts.

2. Remove Lamp Access Door
Some projectors may have covers that come off completely while other models just have a smaller compartment door that gives users access to the lamp housing unit. Projector owners can determine what kind of opening they have by looking at the projector and consulting the manual. 
No matter what the cover or the compartment door must be opened.  You will most likely need a screwdriver to remove the screws that keep the cover or door closed. Once the screws have been removed, you can carefully remove the panel or door. You should also take the time to unscrew any screws that may be keeping the housing unit of the lamp in place before attempting to remove it.

3. Taking Out the Old Projector Lamp 
This is a step that users must take care to complete properly. Doing otherwise may cause the old projector lamp to burst, which is dangerous for both the projector and the user. Because projector Bulbs inside the lamps are very fragile.  They can burst after starting because they have come into contact with the natural oils that are present on fingers.  this causes the glass of the bulb to expand at different rates when it heats.  For this reason you should always use the handle on the lamp to pull it out.  As an example the Christie 003-120507-01 
lamp has two points on the bottom to grab the lamp for removal.

4. Putting In the New Lamp
Once the old lamp is removed, the user can then place the new lamp housing unit inside of the Projector/TV. Users should make sure to slide the housing unit fully into the projector, with the new lamp in the same position that the old one was in. Certain projectors may require that power cables be reconnected to the new lamp. If this is the case, users should follow the manuals for specific instructions on how to do this.

5. Getting the Projector Ready to Run Again
   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.

6. Resetting the Lamp timer
If the projector is working properly, then the user will need to reset the lamp counter so that it can begin tracking time for the new lamp that has just been installed. Some projectors might reset lamp counters automatically, but for those that do not, users may need to do this manually through the projector menu. After completing all of these steps, the projector should be ready to provide hours and hours of entertainment once again.

If at any point you are uncomfortable or unable to perform these steps, please do not hesitate to contact our world class customer service department for assistance.  We have one of if not the best trained representatives to help you with your problems.

10 Tips to Prolong Lamp Life from Pureland Supply

Projector lamps are most important to your projector. Prolong their life with these tips.

1.  Handle the Projector Lamp with gloves. Oils and deposits from hands and fingers can cause hot spots on face of the Projector Lamp, which may result in premature Lamp failure.  Gloves also insure against any smudges that could get on the glass lenses or the projector or the lamp itself.

2.  Operate your projector in a clean, cool, and well ventilated area. A dust free environment would be ideal.  It may be advantageous to look into a ventilation system or air filtration system in the area that the projector will be operating in.

3.  Keep the projector air filters and air vents clean. Clogged filters/vents will not remove heat effectively. This can cause the projector to overheat with an early lamp failure.  During routine maintenance it is recommended to vacuum any loose debris and dust from the projector.  You can also get a can of sealed air to blast out any small particles and dust from the air vents and filter.

4.  Do not place anything on top of the projector or in front of the intake or exhaust vents. This will cause the projector lamp to overheat and fail. Refer to your manual for safe placement of the projector and the accessories.  The vents should be operating in an unrestricted environment that has strong air circulation.

5.  If the projector is built into a compartment, wall, ceiling, or shelf mount, the minimum distance requirement is usually at least 2 feet.  This allows enough space to dissipate any heat that will build up.  Refer to your owner’s manual for specific recommendations.

6.  When you replace the projector lamp make sure the new housing is seated completely and securely. Pureland Supply continually gets phone calls and inquiries from customers that think they have a defective lamp when in actuality they simply didn’t push the lamp in far enough.  Pay attention to the old lamp. Re-install and remove the old lamp a few times to get familiar with the how it fit into your projector. When you install the new lamp you can seat it firmly but without too much pressure.  Use the screws to tighten the lamp into its final position.

7.  Hot Projector Lamps are fragile. Do not move or shake the projector until the Projector Lamp has completely cooled. Shock and vibration applied to hot projector lamps may cause the lamp to break or shorten its effective lifespan.  It is recommended that after operation you let the lamp cool at least an hour before handling the projector or lamp.

8.  Do not unplug the projector until the Lamp has properly cooled. After the projector has been shut off, the fan will remain on for a period. This is required for proper cooling of the lamp.  If the lamp is not cooled properly it will cause the life of the lamp to be shortened drastically.  This is a critical point where many people unplug their projector during use in order to turn it off.  By doing this the lamp is extremely hot and has no air circulation resulting in damage or shortened life of the lamp.

9.  Do not turn the projector on and off frequently during presentations. Each time the projector is switched on, the inrush of power causes stress on the Projector Lamp as does the thermal cycles (heating cooling). Try to minimize your on/ off cycles by not frequently turning on and off. If you are not using the unit for less than 30minutes, use a screen saver or video mute option that some models offer.

10.   Wait until the fans stop running before attempting to turn a projector back on after use. Forcing the Projector Lamp to start before it is adequately cool will cause a thermal and electrical shock to the bulb causing the life to be shortened.

It is recommended that you have your projector serviced and maintained approximately every 2 years.

Preferably have the projector cleaned for dust buildup seasonally.

Insist on high quality projector lamps with the original manufacturer’s bulb inside (Made by Philips, Ushio, Phoenix, or Osram).  All lamps are available for sale at PurelandSupply

4 Common Mistakes that Projector Owners Must Avoid

Your projector might be a small unassuming device you throw in your laptop bag between presentations. It might also be a venerated piece of gear carefully installed into your Home Theater.  Maybe you are tasked with handling a school districts worth of SmartBoards...

In any of these situations there are 4 common mistakes people make when they own a projector. These mistakes are not only annoying but can also be costly to rectify.

1. Ordering a Cheaper lamp that "looks" OK.  

Sure, that lamp might be under $50 and says it will run in your projector but as I mentioned in an earlier blog, your cost of ownership can be over 4X what it should be if you had purchased an Original Inside lamp.  Check with the company and see what brand bulb is inside.  Your old lamp will have markings on that bulb. Make 100% sure your new lamp is the same as the old one.  The adage of "if it looks too good to be true, it probably is" holds very true here.

2. Replacing the bulb portion only. 

Always buy a full lamp if its available.  This is/has been advertised by many companies over the years. They offer an explanation that you can get away with only replacing the bulb since the bulb is the only part of your lamp that goes bad right?  In most cases this is not true. While the plastic and metal structure of the lamp will handle tens of thousands of hours of heat, the other parts, such as the lamp's lens and wires will not.  On a lamp for a DLP projector, there is a special coating that is applied to the lens. That coating blocks harmful ultraviolet and Infrared light from entering the optic path of your projector. Since that coating has degraded over the years, your 2500 hours lamp housing now is only blocking a percentage of that UV/IR light.  That now un-blocked light is attacking your optics.  It will cause the lenses inside to heat-up and eventually start melting. The more concerning problem is that you are exposing you, your family or coworkers to dangerous invisible UV/IR light over a few dollars.   I will say, there are a handful of projectors who use a built in IR/UV filter that is made to handle repeated bulb replacement. These are few and far between. For a few dollars more you will have the peace of mind knowing you are protecting your investment as well as the safety of yourself and those around you.  This BenQ 5J.05Q01.001 is a good example. The lens on the front shows the coating. This is also a problem for cheap lamps. They use an inexpensive coating that will not work as well. The glass has a 'green' shine to it. If you see that send the lamp back.

3. Resetting the Lamp timer without replacing the lamp.  

This is a bad idea. While you are probably thinking you are putting one over on the manufacturer, you are only putting your projector at risk.  The time limit on your projector lamp is determined by the manufacturer of your projector. They determine this by seeing how long the lamp can run before the light output drops past a certain threshold (varies per model) and/or when the lamp may be getting deformed from heating cycles(on and off).  Once a lamp begins to deform, it has an increased chance of rupturing.  If you lamp ruptures while running, the chances of damaging the projector also increase dramatically. That "replace lamp" warning is the best time to buy a new lamp.  If your old lamp still works, then put it away as a backup. Your new lamp will be much brighter and will ensure longer functional life of your projector.

4. Not cleaning your projector often enough.  

This is by far the most common mistake I see with projectors. A dirty projector is a projector that is unable to cool properly.  That will lead to shortening the life of the lamp and the projector itself.  No matter how clean your house is, there is dust in the air.  That dust is pulled into the projector via the cooling fans. Electricity generates a static charge which causes the dust to stick to components inside. Over time that dust will cover the heatsinks that cool electronics like the DLP chip. That dust will build up on the leading edge of the Lamp cooling fan blades. Once enough blades are coated the fan will no longer push enough air through the lamp.  When your lamp is running at 500F and that air stops flowing, you can expect 700F+ at the lamp. That corresponds to increased heat throughout the projector. The lamp will finally reach the temperature for the Quartz to become soft. Once that happens it’s only a moment before the arc tube in the center of the lamp ruptures. I recommend having your projector opened and cleaned at least once a year.  At the least, take a vacuum cleaner and some canned air (air duster, not Perri-Air) and blow out and dust through the intake/exhaust vents on the side.   In the future I will address cleaning to a more direct degree.

There are other mistakes and suggestions, but these are the top 4 that I see. A few weeks ago, I had the pleasure of cleaning some NEC V260X projectors that had never been cleaned in 7 years.  They had enough dust that I could weigh it.  They also had bad color wheels because of the heat and would sometimes get as much as 200 hours before a new lamp would fail. After cleaning them and replacing the color wheel, the NP18LP lamp I installed will run for its entire expected life.

How Close Can I Get? Short Throw Projectors

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.
Steelcase Polyvision PJ905 Projector 2002031-001 lamp

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.

Stay tuned for our upcoming series on choosing a projector. In the meantime feel free to contact us with any  questions you might have at or

What to Do if Your Lamp Stops Working...

...or if your new lamp does not work read these to see if they can help you.

I installed my lamp and now it won’t turn on. Do I have a defective lamp?

There are a few things to check before contacting customer service that may rectify the situation.
·         Make sure your projector is plugged back in.
·         Is the lamp cover fully secured back into place? The projector will not turn on unless it recognizes this access door is closed.
·         It is always best to unplug the unit when replacing the lamp, so make sure it’s properly plugged into a good power outlet. Maybe unplug and re-plug in the projector to be sure.

My projector is plugged in, but I still am not getting light!

     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.

My lamp is projecting a picture, but I have a message telling me to replace the lamp.  This is a new lamp, why is it saying that?

     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.

My projector is much dimmer than I would expect with a new bulb. Do I need to send it back?

     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.

I installed the lamp and my projector is telling me that it is getting too hot.

     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.

I received my lamp but it is not the same as the one I removed.

     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.

My projector has a new lamp, but the color of the screen is still wrong.  I see colors where they shouldn’t be and the picture is either flickering or off color completely. Is my lamp defective?

     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.

I do not see the answer to my issue.  Is there anyone I can talk to?
