Better late than never for any other XP2 owners out there. I've gone through 1 lamp so far with very good results. The key to overheating is cleaning the fan out, i.e. it sucks in a lot of dust particles over time which accumulate on the fan blade and in the vents blocking good airflow. Take a good strong vacuum hose to every vent, then again right when you turn it on. This will get the fan up to speed quickly and assist with removing more dust internally. Eventually, you'll need to open the projector up and clean internally (carefully), but doing the above maintenance will prolong its life and extend the lamp too!
Hi, I had sleepless nights with my customers TDP-P9 projector where I changed the lamp.
The lamp timer resetting gave me headache but now I finally solved the right combo:
1: Unplug the power cord
2: Hold down 'On/standby' 'Input' and 'up arrow' 3: While keeping the buttons pressed, insert the power cord and wait for the projectors led's to flash briefly and then power button to keep illuminated and then starting to blink.
4: Release the buttons and power on, it should now have 0 hours in the timer.
Set the lamp to economy mode, make sure it is being used in a cool room with easy air flow thru the projector. If the problem persists, there are two fans inside and a thermistor that takes the temp reading, there is small adjustment POT on the board to increase the operating temp if needed.
The reason why the projector is shutting off is so the lamp doesn't explode. It's more of a safety feature on the projector, you can reset the lamp and it might work for another 500hours. If the picture is still pretty bright I can get you the reset procedure, but be warn that when the lamp does eventually blow it could shatter the glass inside, so be careful, it shouldn't hurt the unit.
