    I have a MBP 4,1 (pre unibody)

    At times I see lots of red dots or lines on the screen.
    Sometimes I will also have a shadow as if things are out of convergence.


    If I tilt the LCD panel into a different angle sometimes everything goes perfect.

    Can the ribbon cable be the culprit?

    Yes the ribbon cable could be the culprit, or the graphics card more likely.

    I looked up ifixit page and it's a total pain to replace that cable.
    I'll live with the way it is. As that laptop is used for offsite data backup only.

    The 8600GT is a known ticking time bomb. Yours has just kicked the bucket. The temporary fix is to bake the logicboard to reflow all solder.

    The true fix is getting Apple to replace the logicboard with the rev2 they used back when the extended program was going on.

    Either option is a hassle.

    Thanks for info.

    The laptop will be used as a offsite crashplan unit. When the red stuff appears I can still function.

    I will not risk baking the unit. I think the board has to be removed etc.

    If it were ribbon cable only I'd tackle that.
