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 Support@Purelandsupply.com or Sales@PurelandSupply.com if you are not sure if you need a lamp.
 Hitachi
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.
JVC
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 screwdriverto 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.

5 Tips on How to Maintain your Video Projector

 

    Projectors are fragile, expensive pieces of equipment that can perform for years if treated properly. Performing routine maintenance to the various parts of your projector (i.e. the filters, lamp, etc) will help to ensure that you are creating the best environment for your projector to operate. There are certain precautions you can take when using your projector on a regular basis that will improve your the lifespan and protect your investment.

 
1. ARM (Always Read the Manual)
 
   Yes, the manual.  That plastic bag with the paper booklet that you toss in the drawer after pulling the remote batteries out of the bag. That manual is the best resource you have at your fingertips.  Every projector being sold today will have an operating manual in either hard copy or electronic format. Taking the time to read through the operating manual in detail before using the projector is the best way to begin. It will instruct you on the correct way to operate your projector. Your operating manual can also provide helpful maintenance tips that are just for your projector model, i.e. how to remove your projector’s filter cover. Even if you have experience running projectors, each model has their own unique settings and features that might be different than what you are used to. Familiarizing yourself with how that particular piece of equipment works will allow you to tell when something is wrong, and maybe advise on how to take preventative measures to stop things from going wrong in the first place.  
 
2. Choose your Projector Location Wisely.
 
   There is more to positioning your projector than just finding out where the image will look the best. Its imperative to leave at least 6-12 inches of space around the unit to allow for proper heat ventilation. Without proper ventilation the heat that builds up in your projector cannot escape, which can cause damage to the projector’s internal parts and drastically shorten your lamp life.
projector placement
 
Know the temperature your projector operates at. If you think the unit produces a lot of heat, it would be best to avoid placing the projector directly in the path of sunlight or directly next to a heat source(heating vent, wood stove etc). If you have the projector mounted on the ceiling check to make sure that the projector is not directly next to an outgoing vent. The last thing you want is more heat around the projector than it is already producing itself.
It’s also a good idea to not use the projector in smoke filled rooms. This can increase the chance of damaging the projector optics. Smoke will build up on the internal lenses.  That causes the image to dim and in some cases it can cause the lenses inside to fail.
 
Keeping your projector’s environment as dust and dirt free as possible will help as well. Electronics attract more dust than other objects due to the static electricity they create while in use. Dust causes problems for the projector’s filters, and other components if the dust particles get further into the projector.  Routinely clean the air vents if you can. Clean projectors are cool and happy projectors.
 
 
3. Storing your Projector

   Hopefully you use it regularly but for people who use them for presentations primary, this tip is for you.  
Projectors have many parts that need precise alignment to function correctly. Improper transportation or storage of the projector may cause adverse affects for the performance of the projector. The following are a few guidelines for storing your projector:
  • Allow the projector to completely cool down before moving it.
  • Use the original box and packing materials to store the projector if possible. If the original packaging materials are not an option, use a strong box to hold the projector securely and at least 2 inches of a soft material (i.e. cloth, foam, etc) all the way around the projector.
  • Remove the batteries from the remote control.
  • When storing the projector make sure that the storage area will not be subjected to extreme temperatures (hot or cold) that could affect the projector.
  • If you move a projector from one temperature extreme to the other, let it sit for 30 minutes or so until it rises or lowers to room temperature. This prevents moisture problems.
4. Clean your Projector Filters
 
Projectors produce large amounts of heat during use, and this heat needs to be vented to keep the projector from overheating. Projectors have fans that push air around the projector’s operating parts to cool them down, but the air contains dust and other particles that need to be filtered before it cools these components. The filters prevent the buildup of dust that, if left unchecked, would actually insulate the projector. This would keep the heat inside the projector unit which could be very damaging to many of the projector’s components like the lamp, LCD panels, or other internal optics.
 
To ensure that these filters keep performing well, they must be maintained regularly. This is very important since damage to the projector caused by dirty filters may not be covered by the projector warranty.
 
Generally, it is suggested to clean the filters once every 3-4 months(Now is always a good time),.  Always check the projector’s manual first to see if there is a recommended maintenance cycle for your projector. You should clean or replace your filters whenever you notice an excessive build up of dust on the projector’s fan exhaust vent, or if you have been using the projector on a frequent basis. Most projectors will also have a temperature warning LED. If you notice this warning LED occurring, it may be time to clean your filter.
 
The two preferred ways to clean the filter are either to use a small vacuum cleaner attachment to pull the dust out from the filter, or to use a can of compressed air to blow the dust away. Washing the filter with a cleaning solution, or soap and water is generally not recommended as the chemicals in them could harm the filter membranes. 
 
 
5. Cleaning the Projector’s Compartments

  Before you re-install the clean filters or new replacement lamp, make sure to remove all the dust and dirt from the compartments they are housed in. Using the same vacuum cleaner attachment or can of compressed air you used to clean the filters you can remove the excess dust from the compartments as well. It is also time to check the vent fan area for debris buildup. If the fans compartment contains dust and debris it could prevent the fan from operating at the correct speed needed to ventilate the heat that is being produced. 
 
Occasionally the old lamp will burst leaving bits of quartz glass scattered throughout the projector.  That debris can clog fans, preventing cooling.  I have seen that more often than I expected.
Keeping the fans clear of dust and debris is the best first live of defense against early lamp failure.
 
These 5 tips will keep your projector working between lamp changes.  When its time for a lamp, give us a call at 1-800-664-6671 or visit out website www.PurelandSupply.com
