    yellow circle in the middle of the screen -help!

    I am looking for advice as we have an old(ish) sanyo projector however whenever you turn it on there is a yellow circle in the middle of the screen about 2/3 of the total size

    You can see through it and read text behind, but is annoying and can use it for presentations.
    Anyone come accross this before and any ideas how to fix it?

    Sounds like a burn on the blue polariser plate.

      Many thanks for that, it seems that Sanyo alos agree with your thought but call it an "optical panel"
