Here is a quick and easy guide on how to clean the filter on a projector. This works for all different models we have here in the district. This should fix any overheating issues you may be experiencing or sudden shut-offs. Let's get started:
Step 1: Locate the filter on the side of your projector.
Step 2: There is a little sliding latch with an arrow that you can slide to the left to release the protective cover that shields the filter.
Step 3: You can clean the filter by simply lightly tapping it against anything. I'd recommend doing this outside so you don't get all the dust in your room. Take your time so you don't damage the filter.
