Projector Shuts Down - InFocus LP630 Service Manual

Projector shuts down

Projector shuts down on its own.
This is a thermal problem. If a fan isn't running it causes a
power up problem because fans have a sensor line that
prevents the projector from properly starting up.
The problem is almost always a power supply or controller
ECA with a thermal breakdown problem.
Replace the power supply and run projector long enough to
know if that is the problem.
Replace the controller ECA.
