The tint changes colors, green to red to blue, etc. while it is on. What's wrong?

Color shift

Hi there

There is unfortunatelly no section in the Service Manual to explain this sort of procedure.

You'll have to move the LCD panels one by one - millimeter by millimeter.

Infocus Lp290 Will not stay on.

Check the area around the fan and make sure you have good airflow. Put a small fan near the unit and direct the air flow so it cools it and let us know.
