GPU reflow succeeded, still black screen.
I have a Macbook Pro 15" A1226 which at first didn't display an image (black screen). I hooked it up to an external display and also got no image. I reflowed the GPU and now when it boots I can hear the chime and get the grey screen with the apple logo, but then the screen turns black. If I then hook up the external display, the image is being displayed. The weird thing is that the LED screen worked perfectly before the GPU broke down. Does anybody have a clue what the problem might be?
Is this a good question?
