I have the same problem:
1. projector turns on (the DLP sounds noisier than before though)
2. power led flashing amber
3. fans turn on
4. projector light comes on, image appears (power led still flashing)
5. after 5 minutes, projector turns off by itself. Fans turn off, power LED turn green.
With the lamp removed, the behavior is the same, so it's not a lamp overheating. Both Fans spin properly.
Given that other people mention the same problem, this must be a common failure with these MPS2800.

After troubleshooting, I've concluded that the bulb, temp sensor and fans are working correctly, but perhaps the system thinks that it is sensing a surge and powers off. The dispaly never says it's going into standby and the buttons never turn to amber, except for the power button. The manual does say that if the system detects a power surge it will shut down. I plan on troubleshooting this circuit 1st.
