Replaced HeatSink and Now Display Backlight Won't Turn On!
I swapped out the heatsink on my 15" MBP and everythong seemed to go fine. The instructions were clear and easy to follow. My computer had been shutting down immediately and was unusable. I did some research and it sounded like the heatsink was the problem. After reassembling the computer, when I started it up, there was a little PUFF OF SMOKE from the back left of the keyboard (above the "esc" key). And... the screen stayed black, no screen backlight came on.
The repair solved the problem of my computer constantly shutting down, but now I can only see my screen if I shine a bright light on it.
Does anyone know what could have happened? If the thermal compound was touching some little wire or something, could it have caused a short?
Also, how can I diagnose if the problem is a display inverter or the inverter cable?
