    Been my fav machine for the past years
    Howevre this past month I noticed that the screen suddenly has fuzziness appearing during use.
    Sometimes there then sometimes not.
    Saw via google this has some graphics issues.
    Questions
    1. How to check if GPU vs lcd cable/screeen?
    2. Is this repairable? In a sense not being more than a new unit.

    Using Mojave
    Apple Doagnostics CANNOT run. Giving an error loading the test (again a common issue via google)

    Thanks

    Try connecting an external monitor and see if the same issue shows on both screens, only on the external or only on the built-in screen. If only on the built-in screen then its likely an lcd cable or screen problem. If on both, possibly the graphics card.

    Screen and/or cable is replaceable. Dedicated graphics chip can be disabled permanently. Worst case the logic board is at fault its also replaceable and not costing near the price of a new unit.

    Thanks. How can I disable the graphics card? So I can troubleshoot if it also appears even when disabled.

    Thanks
    However I called BTB service center. The unit model is considered Vintage thus no more service parts.
    Thus dead end for that option.
