How to Fix a Faulty LCD Projector

How to Fix a Faulty LCD Projector

FacebookTwitterPinterestGoogle+StumbleUponReddit

Many people and companies are using LCD projectors nowadays. In different universities, classes use LCD projectors in discussions and the same for business meetings and presentations as they are used by many corporations. People now also use the projectors as part of their home entertainment systems.

What is an LCD Projector?

LCD projector refers to a kind of video projector that is used to display or “project” an image, video, and computer data on a flat exterior or simply a screen. In order to project images and other similar presentations, light is projected from the Metal halide lamp to a prism placed in between the three poly silicone panels. Despite the advancement of an LCD projector, there are times that it simply malfunctions. There are different kinds of LDC problems and for every faulty LCD projector, there is a corresponding solution.

Materials Needed

Basically, the main thing to do in fixing a faulty projector is to test and then replace or change the specifications. For image distortions, it’s the setting of the projector and the computer that should be changed. For faulty images the following might be needed:

Screwdriver

Lamp replacement

Mirror replacement

Pliers or tweezers

Fixing LCD Projector that do not Display Computer Images

If the projector shows DVD, CCTV, and VHS but will not project the image from the computer, the following steps should be done.

Using the manual from the manufacturer, check the computer’s refresh rate. Adjust the settings of the refresh rate.

Go to start, click Control Panel then proceed to Appearance and Themes then go to Display.

Go to Settings Tab then proceed to the Advanced Option. There should be the Monitor options.

Checking the refresh rate in the manual of the projector, adjust the settings accordingly.

Repairing Projector with Yellowish Image

Step 1: Check the LCD Panel

A yellow image from the projector is usually the result of a broken LCD panel. To see which panel is broken, pop the cover of the projector using the screwdriver. Make sure to refer first to the manual before opening the projector. Inside the projector, mirrors are positioned to separate each colored LCD panel: red, blue and green. The panels are placed around a prism that mixes the three colors together to display an image.

Step 2: Test Each LCD Panel

In order to test each panel, the projector has to be turned on. Make sure that no sensitive parts are touched to avoid problems. Cover each panel with a paper or cardboard and see which panel does not reflect the color well. The malfunctioning panel will not be able to respond to a signal. It will also show which panel does not reflect the right form of the image.

Step 3: Replace the Malfunctioning Part

Using pliers or tweezers, take out the malfunctioning panel. This step may not be applicable to all projectors so check with the manual how to detach the panels. Once the malfunction part is taken out, position the replacement.

Step 4: Check the Panels Again

Check the panel by shielding it again. See if it already reflects the right color and the correct image quality.

Step 5: Cover the Projector

Screw on the lid and test the projector.
