Projector

=Troubleshooting Projectors= By Kim Ramirez and Megan Phillips

Let's face it- projectors are incredibly useful in the classroom but when they seem to go out, do you know what to do? Here are a few tips for troubleshooting some common problems with projectors!

First things first, make sure the projector is not in standby mode and that it’s projecting from the right source. If it is still not projecting the image, check the following…
 * Problem #1- Projector on but no image**

//Video connection cables:// Make sure that none of the pins in the video connection cable are bent or damaged.

//Problems with the lamp itself:// Make sure that the projection lamp is sitting firmly in its housing. If the projector has a lamp time, check whether the lamp life has expired. Check the lamp ballast. This is what provides powers to the lamp. Buy a new one if needed.


 * Problem #2- Projector Overheating**

This is a very common problem among projectors! While it is difficult to give exact troubleshooting instructions because projectors vary from manufacturer to manufacturer- here are a few tips for when your projector is overheating.

1. The first thing you want to check is the fan. Do you hear the fan running? Is anything constricting the fan and its vents from working properly? If these are not working properly, the projector is not able to cool down like it should.

2. If your fans and vents are working fine, check the filter. Many manufacturers will have a foam filter so it is important to make sure that the filter is clean and not plugged, allowing air to filter in and out. A filter should be cleaned once every three months.

3. Next, you should check how your projector is mounted. Overheating is VERY common in projectors that are mounted upside down.

4. Where are you using your projector? If being used in direct sunlight, this could cause it to overheat. It is recommended to protect your projector from direct sunlight to avoid overheating.

5. Check the power supply. A faulty or inconsistent power supply can overheat the lamp in the projector which would drastically reduce the power supply and create a shorter life for the bulb. Purchase accessories that will stabilize and keep the power supply consistent before getting to the projector.

6. Try using a fan near the projector to increase air flow.

7. If problem persists, contact manufacturer.
