    Exclamation Mitsubishi Classroom Projector Flickers Between Yellow/Blue/Green Tones

    Hey all

    I had a question about our classroom's projector. When plugged into multiple laptops it still flickers between the multiple colours. It shows on the whole screen not just in patches (which I've heard is a good thing; it's most likely to cable other than a broken bulb hopefully). We can move the VGA cable around when plugged in and get it back to white but have to prop it up somehow against an object to keep the white screen. If it moves even slightly it jumps back to a random colour.

    The cable has been replaced and it still happens. To me it seems like the pins are loose or wonky but I've checked that out. Unless we've been unlucky twice and received a dodgy cable. One is a school laptop one is my personal one, and both work fine on other projectors in other classrooms. Could it be the lead again despite already being replaced or is it likely it's something in the projector itself? The whole thing is wired up through pipes seeing as it's for classroom use so it makes it difficult to check out leads or wires to see if they're loose.

    Does anyone have any ideas of what it is and how to fix it?

    Thanks!

    -Rachel

    Check the laptops or projector, see if the pin slots are full or the slot is loose in any which way.

    Have you tried putting a vga lead directly from a laptop to the projector. If that works, then chances are you have a dodgy connection somewhere. Good luck.
