rapidly flickering display backlight
I got the problem that the display backlight of my MBP 2009 13" flickers rapidly like 7-10 times a second. And a scraping noise which is louder when the screen is brighter. When the backlight is off the scraping noise disappears.
I just changed the display but no change. An external display works without any problems.
I hope theres a fix for my problem.
Is this a good question?
