    so i was watching a youtube video last night, then all of a sudden the screen went black with a 1 second audio loop - no response to anything other than power button.

    turned it off and back on again.
    i get the grey screen with the apple logo but i have jagged lines all across the screen (a slight green tint).
    the progress bar goes to about 75% then the screen flashing with a big green bar across the screen, then goes completely grey and then reboots - this repeats and it never fully boots.

    it's a macbook pro 15" late 2011 (high res display).

    have tried resetting SMC and PRAM - made no difference.

    is this now f'ed?

    here is a video of what happens during boot - https://goo.gl/photos/Lyaa2jVT9WYRMvB38

    I'd say your GPU is gone, which is inherent in 2011 MBPs. Call Apple, as they have a repair program, for affected computers.

    i think mine has already had that fix (or maybe it was my previous MBP).
    i can't remember which!

    i'll investigate this further.

    Many users who've had their computer repaired have needed to have it repaired a second time or more. Definitely contact Apple.

    iv'e been given this link on the apple discussions form -https://www.apple.com/uk/support/macbookpro-videoissues/
    which suggests there is a repair program for this.
    however when i punched in my serial number it suggested that my repair/service options had expired?

    That service program won't be listed on that page; all you're checking for there is that you have the right model. If you have one of the listed models, your computer is covered by the program.

    GET THAT COMPUTER TO AN APPLE STORE TODAY! (shouting is intentional)
    That means, right now!

    I believe the "RadeonGate" repair program has been extended.
    But again -- DON'T WAIT!

    Comprende?

    however mine is an Nvidia GPU, not an AMD Radeon.

    Then it is not a Late 2011 15" MBP. The Late 2011 15" only came with a AMD Radeon HD 6750M or 6770M.

    I have heard of people getting false results from the serial number check, but the device is covered when Apple checks it. Good luck with your appointment! Let us know how it turns out. I got my 2011 MBP repaired in Dec 2015.

    it's in for repair now.
    free repair under the extended warranty (would have been £400 otherwise).
