Macbook pro start up fails: blue-grey screen

[mononoke82]

MacBook Pro 15", Early2011, Intel i7, 2GHz (sorry don't remember what operative system I was actually running)

Issue: screen split in half and started flickering and MacBook went off. when restarted loaded to show the apple logo and progress bar in a blu-ish/grey screen.

I have tried the following:
1 SMC: nothing
2 NVRAM: nothing
3 Boot in safe mode: power then shift and nothing
shift+command+V: tried to read it through but sorry don't get a word!

4 File system consistency: fsck -fy and it says that the volume Macintosh HD appears to be ok.
5 Apple hardware test (extended) appears to be ok too
6 Disk utility??? doesn't work! I used the Mac OS X Install dvd, pressing C and nothing...

Help...what am I supposed to do...at least to recover my files

Please be kind as I'm not an IT orientated person and I hope I've explain the problem clearly enough.

Thank you so much for any help!!

Your MacBook is affected by a failed Radeon gpu: https://www.macrumors.com/2017/05/20/apple-ends-2011-macbook-pro-repair-program/


To recover the files, place the hard drive into a usb enclosure and use another mac to access your files.

OP:

The MBP you have has "RadeonGate" (research it, failed GPU).
There's no real "fix" for it other than to replace the motherboard -- no longer worth it on a 7-year-old computer.

There IS a way to "permanently disable" the GPU so that the MBP boots and run using integrated graphics only, but I understand it's a convoluted process. There are threads posted here on how to do that.

Best solution is to find a replacement.

You can take the old drive out and access it using either a USB3 enclosure or perhaps a USB3/SATA dongle (can be found online).

To open the case, you'll need a Phillips #00 driver.
To take the "bosses" off the internal drive, you'll need a TORX T-6 driver.

Just take all the screws off the rear panel and it lifts away.
The drive "lifts right out".
Then disconnect the ribbon cable and it's free to connect elsewhere.
Again, the little "bosses" on the side of the drive can be taken off with the T-6 driver. You might even GENTLY use pliers to loosen them, but be careful.
