MacBook came in with quarter fanspin, turns out one of the legs of U6100 was ripped off the board. ran a jumper from the chip to the board and it is now booting
When booting about 1/3 of the progress bar the screen will flicker and will continue to startup normally, but if it doesn't flicker when it gets there it will just sit on the loading bar at 1/3
In ASD OS "IC0R" fails looked at u5400 area looks perfect.
It's acting really strange symptoms are like the usual U8900 job. But have reflowed and soldered that twice now. Sometimes it will freeze up when using it and this is the log I get, CPU panic?
