Projector Screen Tensioning

Does your manual projector screen not pull down easily? Will it not stay down after you jerk it downward a few times? If so, you might need to re-tension the spring in charge of maintaining the position of the screen!
Today, I uninstall my screen, tear it down and re-tension the spring inside to make it work properly again. I'll show you my trial-and-error process so that you can attempt your own fix--before you trash your manual pull-down screen and buy a mechanized one! The crux of this process requires a unique tool, which can easily be made out of scrap angled metal (I used aluminum, but it could be iron or anything else strong and thin).
Please leave your comments and questions below and I'll try to respond as quickly as possible!

Also another tip. If you take the other end off and pull the screen out of its casing you can then tension it up with the end where it locks into the end cap if that makes sense. No need for tensioning device. Thats how I did it anyway

Came across this video today. very helpful, I made a tool similar to that and used the zip ties. Putting on the new end cap was hard enough without having to hold the screen case. This video helped me repair a 3 year old 8' carpeted tripod screen with a plastic end cap.

Thanks so much! My screen seemed to have no tension when I first got it, or lost it due to my meddling with it and your video helped me understand how the mechanism was supposed to work.

This is a great, clear instructional. Much appreciated!

Thank you Jim, you are awesome!

Thank you for this. I have a screen exactly like yours but It's hard to roll back up. Will try adjusting tension.

super bro

My problem was a little different. I could not get the screen to roll up.. The latches would not release to allow the screen to rewind. Your video helped me to see the inside and understand how the latches work. Thanks for your video.

The plastic of One side of my bar it's broken, the part where it's the spring. Can I buy that part somewhere?? I need to change that mechanisms

If the screen is just stuck, carefully hang it upside down. While holding this position, pull the slat bail while gently tapping the screen case on the floor. In most cases the screen will roll back up freely. I hope this will help you guys.

I have a spring loaded screen like this and I'm planning to motorize it with a stepper motor and a wifi enabled microcontroller. It is a straightforward project in my head, I just wondered if you had tried this or thought of trying this? Since you said your next screen will be motorized

nice shirt! thanks for the tips, i broke my end cap, and am looking to purchase a new one... but not i know how to fix it.

[@AmitChaudhary-ze4iq]

Which gear is that?

[@m.a.r.1125]

Thanks for the video just what I was looking for. Now do u think it would be possible to peplace the whole screen itself? I want to try to replace my white screen with a grey one. I'll just buy the ALR cloth and cut it to size and insert back in the housing.

Hi, I am trying to reattach/glue the projection screen onto the roller. You mentioned in the early part of the video that one needs to add the tension back by rolling it 12 to 15 times. But towards the end of the the video you did 2 or 2 and a half turns only. My question is should I add just 2 or 3 cycle AFTER I rolled up the screen into the box or I need to crank it up until I cannot turns anymore. Thanks.
