Trust me that the Mainboard needs replacement.
I am very familiar with the PE8700's as I am a ASP Technician for BenQ.
Visit www.BenQ.com and look for the link to your country - you should be able to allocate a Approved Service Provider.
Must warn you that the Mainboards on these models are quite expensive.

I had the same problem.
First thing to do is look up the owners manual, unless you happen to still have it, then verify the the sensor for the second (or rear something that sounds not like first) temp sensor is going off. If it is basically the fan that sends air into the lamps compartment may be clogged. I have had mine for several years and recently had the same problem. I almost went out to buy something new until I convinced myself that there was no harm in taking it apart and trying something. Good thing too, since all I had to do was clean the fan and reassemble. After that it stopped turning off by itself and I haven't seen any red lights.
Good luck to You!

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
