My Acer PH530 overheats and shuts down after 15 minutes.
I'll be watching something on my projector for about 15 minutes before the screen goes funny colors and the projector makes a funny noise and shuts down. I've taken it apart and cleaned it out once, which seemed to help for about a month, but now it is back to overheating.
Re: My Acer PH530 overheats and shuts down after 15...
Mine does the same. When it was still under warranty I kept sending it in to get it fixed, but Acer never fixed the problem (rather they caused more problems). I sent it in for repairs 4 or 5 times, but eventually the warranty expired (after they told me they would extend it from the dates of the repairs). I haven't found a solution. If you do please let me know. Anyway, I don't recommend this projector to anyone else. AND, I certainly don't recommend Acer's customer service. Their warranty is worthless.

I seemed to have had the exact same problem... I had placed the projector on top of a small book (to raise the unit), however, did not rest the feet of the projection unit on the book and it overheated and turned off, as a result. (The bottom of the unit was making direct contact with the book which caused it to overheat since not any air was passing through between the two)
After letting it cool for a while and powering it up -- it would usually power off completely for about 15 minutes. After a little thinking, I thought it may be the lamp/bulb and waited a couple of years and bought one online that arrived yesterday.
I installed the new lamp/bulb this morning and it did the same thing. It powered down about a half hour later. Bummer.
I reset the machine to factory defaults and checked to see if it had the 1.03 firmware... It did
Then went through the settings in the setup area and turned off the 'prevent pic screen saver'... Reset the 'lamp hours'
I doubled checked the lamp/bulb installation... Turned it back on -- same thing -- it shut off after about 15 minutes or so... Then unplugged the unit and turned it over and took out the 4 or 5 chassis screws and loosened and took off the side panels and blew onto the fans and circuit board areas and gently pounded the sides to shake anything that shouldn't be there loose and put it back together.
i powered it back on and now it's been working for about 2 hours and 16 minutes!
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!
Turn on the projector and laptop and connect the vga cord to the projector and the laptop (making sure there is a secure connection so it is tight but not overtight) and hold down function when your operating system has started (windows only mac is different) and press either F1 F2 F3 F4 or which ever one has the picture,icon, of the laptop and the external display.
