Dead display and external display connection
The computer will start ok and i have successfully connected it to another through firewire and can use the hard drive that way. however, the display is completely black and i can't use the external diplay connection either. i have replaced the LED Driver Board already, but problem is still there. can this be something other than a bad logic board?
Es esta una buena pregunta?

i was able to heat the graphics chip as suggezted and it worked like a charm! the dispaly and the external connection are now working perfectly. thanks! this saved lots in replacement costs.
