If your projector screen has waves, you can fix them by adjusting the legs of the screen. If necessary, you can also tighten them. Moreover, you can clean them with a soft cloth. If this still doesn’t work, you can purchase a re-tensioner.
Retractable projector screen tension loosens or over-contracts
The spring that controls the retractability of your projector screen can loosen or over-contract. If it is too loose, the screen will not roll back up into the housing. Luckily, there are a few ways to prevent this. If you notice that the tension is loose, simply tighten the spring. If the problem persists, contact a professional repair person for assistance.
First, you need to remove the screen from the projector. You’ll also need a work area. The screen itself has two end caps that connect to the spring. Hold the end cap firmly during the process. If the screen is too loose, you may need to purchase a spring re-tensioner.
Next, tighten the tensioning spring by turning it clockwise. Do this twelve to fifteen times to ensure a good tension. Then, insert the cap into the housing and screw it in place. After that, work down and up, until the screen is taut.
Retractable projector screen re-tensioner
If your projector screen has waves, you can fix the problem by adding tension to the spring that holds the screen in place. This is an easy task that you can complete on your own in a matter of minutes. It will prevent the screen from dragging while it is being pulled up or down.
There are two main types of projector screens available. One type is fixed with a frame and is mounted near the ceiling. Another type is retractable, and is mounted manually. These screens are easy to set up, but are not as smooth as motorized screens.
If you have a retractable projector screen, you may have issues with waves in the screen. This is due to a lack of tension on the screen. A re-tensioned screen uses cables and tabs to exert a constant pull on the bottom of the screen to keep it from wagging.
Adding tension to a retractable projector screen
If your projector screen is causing waves, you may need to add tension to it. The manual for your screen should tell you how to do it. To add tension, twist the screen handle clockwise 12 to 15 times. Next, place the screen in the housing and tighten the screws. This should help the projector screen retract and roll smoothly.
Next, measure the screen’s width and height. The width should be at least 1.33 times its height. Too much or too little width could cause wrinkles. It is a good idea to start with the shape of the screen, before adding images.
Another way to correct screen waves is by adding horizontal tension. To do this, hold the pull bar. The screen will stretch out from the center, which will reduce the waves. The bar should also develop an upward curve. However, it is unlikely that this will fix the screen’s waves completely. But, it might give you a good idea for future projections.
After using a projector screen for a long time, the fabric will become saggy and creased. This can affect the image quality. To fix this problem, you can tighten the tension mount or heat up the theater room. You may also use an iron or blowdryer to help get rid of the wrinkles.
