Projector For Reading Problem Projector Shows Vertical Red Lines. Is There A Fix?

Projector shows vertical red lines. Is there a fix? - projector for reading problem

I have a projector of 4600 ProScreen Philips LCD. In this draft red vertical parallel lines in the picture. Sure, I might buy a new projector, but I was hoping that there is a way to fix it. I read that the dashboard could be, but someone has a solution that could solve or minimize the problem?
