You know that feeling when you’re in a dark room and your projector just won’t turn on? Yeah, we’ve all been there. Here’s how to test projector lamp is bad?
Check the lamp status on the projector
In order to check the status of the projector lamp, you will need to consult your projector’s user manual. Generally, there is a button or menu selection that will tell you how many hours are left on the current lamp.
Diagnose the issue
There are a few ways that you can tell if your projector lamp is bad. One way is to look at the image that the projector is projecting. If the image is dim or has a yellow tint, this could be a sign that the projector lamp is bad. Another way to tell if the projector lamp is bad is to listen for any strange noises coming from the projector. If you hear a loud buzzing noise, this could be a sign that the projector lamp is beginning to fail.
Replace the lamp
If your image is either very dim or completely dark, it’s probably time to replace the projector lamp. Replacing the lamp is a pretty simple process, but it will require you to open up your projector and may void your warranty, so be sure to check your owner’s manual first.
Before buying a new lamp, be sure to check the model number so you get the right one. Once you have the new lamp, follow these steps:
1. Turn off the projector and unplug it from the power outlet.
2. Remove the screw that secures the lamp cover and open the cover.
3. Carefully remove the old lamp and dispose of it properly.
4. Insert the new lamp into the projector and secure it with the retaining screws.
5. Close the lamp cover and replace the screw that secures it.
