Hi all,

Am attempting to Frankenstein a working MacBook Pro out of two late 2011 13 inch MacBook Pros.

One has USB ports which don't work (one does nothing, the other brings up the overcurrent so usb is disabled message) - but otherwise works fine.

One displays weird distortion on the screen - see attached video and photos. I swapped the displays, but both displays perform the same. Any ideas? Or is it likely a GPU failure?

Thanks :)

I would be surprised if it's the GPU. Normally the integrated Intel HD Graphics chipset is pretty solid. Could be a bad or flaky LVDS cable or one of the other video cables or even the connector.

Since you have a spare MBP to cannabilize, maybe you can try swapping the cables.

Thanks - I swapped over the screens completely including the cable and the same issue occurs - maybe it is the connector on the logic board :O
