- There are a number of things that can make a projector overheat. The most common is it not getting enough ventilation. Make sure there’s enough space all around it to allow good air flow. If there is, it may have a blocked filter
- The filter hatch is normally underneath your device; the user guide will show you exactly where. Open this, unscrewing if you need to, and remove the filter
- Move the filter away from the projector and put it on some newspaper. Use a can of compressed air to give some short blasts to the filter to get rid of any dust. Look in the filter compartment of the projector - if there’s any dirt in there, a couple of quick spurts of the air should get rid of them
- Put the filter back in the projector, and replace the hatch securely
Sorted. Now you can get back to that movie.
Always refer to the manufacturer’s manual for specific details.
