MacBook won't boot - no chime - black screen - fans on high rev
my macbook pro won't start at all. If I push the on button, nothing happens despite status LED is shortly bright, then (0.5 sec) dim. There is no chime, no screen, no capslock led when pressed. And the fans rev like !&&*...till I power it off.
Tryed everything of the obvious solutions... PRAM /SMC / RAM swaps etc. ...nothing
Is it a failing logicboard or a power issue (the logicboard doesn't get the signal to turn on ? )
Anyone any idea?
Still no luck :(
