Buying Projector Lamps/Bulbs

Be careful on buying the cheapest projection lamp. When lamps are made for a certain projector manufacture the lamps sent to them pass a certain quality threshold. Some lamps that do not pass the quality requirements are sold to independent vendors. A lamp not bought from the manufacture may not last the hours you expect from it.

my projector is projecting an image that is getting darker and darker


hi
this sounds to me like the projector lamp is coming to the end of its life. projector lamps last about 1000 hours of reasonable quality, but if it gets turned on and off regularly then that number will decrease.
you might want to buy a new lamp if there not to expensive or maybe to into having it refurbished.
also dirt in the projector can decrease brightness. so maybe you could see if the manufacturer will clean it for cheap
hope that helped

Lamp Replace Counter
Be sure to reset the lamp replace counter after Lamp Assembly is replaced. When the lamp replace counter is reset, the LAMP REPLACE Indicator stops lighting.
Note : Do not reset the Lamp Replace Counter until after the projection lamp is replaced.
1. Turn projector on, press MENU button to display the On-Screen Menu. Press Point left or right button(s) to move the red frame pointer to the Setting Menu icon.
2. Press Point down button to move the red frame pointer to "Lamp counter reset" and then press SET button. The message " Lamp replace counter reset? " is displayed.
Move the pointer to [Yes] and then press SET button.
3. Another confirmation dialog box appears and select [Yes] to
reset the lamp replace counter.
Note : Do not reset the Lamp Replace Counter until after the projection lamp is replaced.
This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling may result in accidents, injury, or create a fire hazard.
 Lamp life may differ from lamp to lamp and according to the environment of use. There is no guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their life in a shorter period of time than other similar lamps.
 If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE INDICATOR lights up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down.
( Follow carefully the instructions in the LAMP REPLACEMENT section of this manual. ) Continuous use of the lamp with the LAMP REPLACE INDICATOR lighted may increase the risk of lamp explosion.
 A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its lifetime draws to an end. Risk of explosion may differ according to the environment or conditions in which the projector and
lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN.
If a lamp explodes, disconnect the projector's AC plug from the AC outlet immediately. Contact an authorized service station for a checkup of the unit and replacement of the lamp. Additionally, check carefully to ensure that
there are no broken shards or pieces of glass around the projector or coming out from the cooling air circulation holes. Any broken shards found should be cleaned up carefully. No one should check the inside of the projector
except those who are authorized trained technicians and who are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those who are not appropriately trained to do so, may result in an
accident or injury caused by pieces of broken glass.

PT-AE 900U LAMP GOES OFF


does it stay on for about 10 minutes, then shut down? If so, that is indcating the lamp is near end of life, according to an hour counter built into the system.

The growling is probably the Dynamic Iris which has had a lot of issues. Mine started making noise after about 1 yr 9 months of ownership/use. Since I bought it with an AmEx card which doubles manufacturer warranty, I was able to send AmEx the quote, and they sent me a check, and I got it fixed.

The cheapest place I found for a replacement lamp is through one of the 2 or 3 sellers on ebay; I bought one last week for $260 delivered. Lamp is very easy to replace, but then follow instructions for resetting the lamp hour counter, or the unit will still think the lamp is near end of life.

Hi there.

This is definetly the light tunnel issue. After searching and a million phonecalls, I tracked down a place that you can buy the light tunel for $41 on their own and simply put that in, making the projector good as new.
I Have the phone number of the place and also the link to the forum giving you fully pictured diagrams of how to change the light tunnel, and also I have a service manual if anyone would like it to be sent to them.

Cheers
Russ
