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. 

NEC:
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.

Toshiba
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.

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?

Hitachi CP-X306 and it's DT00841 Lamp

hitachi lcd projector using dt00841
     The Hitachi CP-X306 is an older LCD video projector with a great reputation.  If you own a CP-X306 that uses the DT00841 lamp, you already know of the hi lumen output of 2600 lumens.  For its time, 2600 lumen (2060 in eco mode) was a bright and useful projector.
The CP-X306 was one of the earlier XGA models.  It has a native resolution of 2014 x 768 which would give you a native 720p resolution if used for Home Theater.

The DT00841 Lamp runs at 220W and feeds a 0.6” set of LCD panels. That gives the projector a respectable 500:1 contract ratio (respectable for 2008 when the unit was first made).    In data mode, the projector can upscale to 1600 x 1200 dpi.  This isn’t useful for home theater but for certain computer driver display applications it is very useful.
The Input panel is one of the most useful features of the CP-X306. 


The CP-X306 also has the capabilities to support Composite,S-Video, Composite, and Dual VGA in (D-sub 15 pin).  The option to use the network jack is a plus. You can then use a newer OS like Windows 10 to connect via a network, so you can skip finding a VGA cable long enough.  If your needs require it, you can also control it via RS232 or USB.  

The Hitachi CP-X306 is a highly flexible projector.  If you own one or plan to buy a used one on eBay give this link a click to treat your Hitachi to a new lamp.  The DT00841 sold by PurelandSupply.com has an original Ushio brand bulb to ensure proper operation. 
Your Source for replacement projector lamps
Place an order before 5pm Eastern time, and the DT00841 lamp will ship the same day. All lamps have a 180-day replacement warranty.
