Re: shuts off on its own.
This can be from a number of issues. I must answer you genericaly, because I have no service information for your model type or worked on the model you have.
Common problems that cause power down for the lamp:
Failing power supply, most likely due to components that are changing spec with temperature. These are parts that have become thermo sensitive.
The lamp or its load effect is causing some over heating in the unit, or one or more of the boards themselves are overheating. This can be from a cooling problem. It is very common that maybe a cooling fan is not functioning properly. Faulty components in the power supply, or the lamp supply can also cause this effect.
A defective lamp can also cause the power supply, and or the lamp supply to go in to protection mode.
The service tech would start by replacing the power supply for the lamp, and testing the cooling fan's performance. He will also try a new lamp. If the unit still has a fault he will try the main power supply. The next step is to start replacing modules (boards) to find the one that is cauing too much current pull.
After the unit is serviced and apears to be working, the service tech should run a temperature test on the unit over a number of hours to make sure that there is no overheating. He should also run a current draw test to make sure that the set is in specs.

chances are its the projector itself that you are having an issue with, one more thing that you can do is for you to clean the filters, try cleaning the filters and try reinstalling the lamp, then power it back on, if you are getting the same thing still, have the projector service or if within warranty have it replaced. best i got. Thanks for using Fixya!
Did you rest the lamp hour after replacing the lamp. It is recommended the you have to reset the lamp hour after replacing the lamp. For resetting the lamp hour do the following.
1. Power ON the projector
2. Press the Menu button
3. Select OPTIONS
4. In OPTION menu select Lamp Reset and press the enter button.
(If the lamp hour counter is at the heights level then the projector will turn OFF after some time.)
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.
firdt off, did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast. try projector doctor online.
1) Press the POWER button to turn your TV on. Make sure you are set to Cable/TV reception. If the "replace lamp. Reset Lamp timer" notice appears, press "EXIT" on your remote. 2) Press and hold the VOLUME DOWN BUTTON on the TV set (not the remote, the actual TV set) 3) Continue to press and hold the VOLUME DOWN button and press and hold the PIP (Picture in Picture) or SPLIT/PLAY button on your REMOTE control (your are pressing and holding BOTH of these buttons at the same time now). 4) After 5 or 10 seconds (be patient), the lamp serice menu will appear and say your lamp counter has been rest to '0' (zero). That's it, you are all done.
Now, I continue to have the power shut off after a few minutes of play. I think it is a problem with the cooling fan. Damn it all anyway.
