    Like I said, I have a Mitsubishi HC3800, which I got from my friend. I've been using it for last couple months now, but I have never seen this until this morning. There's a strange purple-yellow line thats in the center of the screen. It's very shaky if that helps at all. Can this be fixed?

    Try and turn the focus fully one way or the other and see if the line comes into sharp focus. It looks almost like a long strand of something is behind the lens. DLP projectors do have a sealed light path so dust etc should not be able to get inside but you might need to take the cover off to have a look if it turns out to be something that has got inside.

    Here's video of me trying to focus it: Streamable - simple video sharing

    I can't get a sharp focus, but I agree that there might be in the projector. Unfortunately, I don't know anything about projectors. Do you have any suggestions of specific areas that I should check?

    It looks like it's moving about which is probably being caused by the cooling fan inside. I am fairly convinced that it is a strand of material that is trapped inside.

    You could try and remove the casing and take a look inside but if you are not confident doing that you would need to find a local repair shop to do it for you. I guess they might charge £20-50 to open it and inspect it.
