I have a MacBook Black. For about the last six months I have had a strange screen flicker when I:

• start my machine and
• plug in the power cord of my machine

This morning when I woke up my computer the screen backlight did not turn on at all. When I held the computer in direct sunlight I could see the screen and I could tell that everything was working normally (other than the backlight).

Pressing the screen brightness controls (F2) brought up the brightness panel. The brightness panel informed me that the screen was at maximum brightness.

I did a bit of Searching and this is what I found:

• This post describes how to buy and replace a macbook screen. Do you think that this would solve my problem?

Additional info:

• I am running 10.6.4
• I recently upgraded from 10.4. I experienced similar issues in 10.4. I am pretty sure that this is a hardware issue.
• The problem does not occur when the screen is at a specific angle. It usually only happens at startup/wakeup or when the power is plugged/unplugged.
