Display is gone but can still faintly brighten the dark screen
I am trying to troubleshoot whether or not to replace my whole LCD display. It seems my display went dark after an update to 10.6.7.
Here are the symptoms:
Even though I have no display, I can brighten and darken the dark screen. I assume the back light is still working.
I can use an external monitor. I believe that rules out the graphics chip.
I can share the screen.
Computer still operates normally otherwise.
Has there been an issue with this latest update? Seems to much of a coincidence.
What would be the recommended course of action to take and test before replacing the expensive LCD unit.
Esta é uma boa pergunta?

Please forgive my ignorance. I am having some problems comprehending exactly what is going on with your laptop's screen and it's ability to produce a viewable image. You state you can brighten and darken the dark screen. Does that mean that there is no image on the screen and you can make the screen go from a blank black screen to a blank white screen? Please define that better for me. You state that it went dark after an update. Would you please elaborate on this issue. Time frame etc...

I can affect the screen slightly with F2 and F1. There is no image. Basically it looks like there is a back-light functioning.The screen does not go to white. I had the screen up for a little bit after the update, then it went down. I cannot see the desktop even with the flashlight test.
