How to Troubleshoot a Projector
- 1). Check the cable connections running into the projector. If the cables are not completely inserted into the device, you are not going to get a clear signal and the picture quality will drop.
- 2). Clean off the air intake vent with a soft cloth. If this vent becomes dusty, it locks the equipment's heat inside, causing it to overheat. Once the projector reaches a certain temperature, the hardware shuts down (the exact temperature is going to vary depending on the device you are using). If the vent is deep, spray a few shots of compressed air into it to remove dust build up.
- 3). Move the projector away from enclosed areas. You also don't want other items touching it, outside of a ceiling mount or desk. When a projector is enclosed, the heat has nowhere to go and the equipment is more likely to overheat.
- 4). Check that the cap is removed from the projector. If you have the projector on but nothing is being projected, it may be because the cap is still in pace. If the cap is already off, it means the lamp is burnt out. Remove the lamp and insert a replacement to begin using the projector again.
