I have a "classic" projector screen, with a projector connected to my PC. My problem is that when I lower it, it no longer locks and constantly rewinds!!! Is there a way to fix it myself???
Well, apart from dismantling the mechanism, studying it, and remedying the problem if possible, which risks not being able to reassemble it (it's often like that), there's not much to be done. -- The urgent is done, the impossible is in progress, For miracles, please allow time ...
