LCD backlight not working
I'm having this same issue with my iMac A1225. Although the top half has the dark gradient. Below is what I got back from the computer repair man
'INSPECTED MACHINE, CONFIRMED THAT THE LCD BACKLIGHT AT THE TOP OF THE
SCREEN DOES NOT APPEAR TO BE FUNCTIONING AT ALL. NEW DISPLAY LCD PANEL
My LCD replacement was quoted at 1600.00(AUS)to fix!! I'm furious, I consider this to me a product default and am chasing up with Apple. Will let you know how I go. Otherwise would appreciate if you've had any luck.
Is this a good question?
