I replace a loud fan as per "Installing MacBook Unibody Model A1342 Fan" by Walter Galan on ifixit. Followed ESD precautions etc. Now Mac powers up but just have a black screen. The white LED is on, the hard drive spins up , I tried shining a bright light to see if the LCD was not backlit :no presentation. It stays on and will shut off if hold down power button, Help Please!

Simran, Thanks for your help. Stripped the whole computer down found a six lead IC on the Logic board almost between the USB ports with all leads covered with white corrosion (crystals were actually touching). Not very pretty but replaced the board and my computer is back up. I ordered the chip and will replace that SMD and see
if that resurrects the logic board.

Would you mind telling us exactly which IC this was so we can be on the lookout for others with this problem?

if there is corrosion you can wash it properly or resolder it . then check its working. from my side it should be working . changing that ic is the last option
