Backlight stopped working for the 2nd time after replacing mainboard
My Apple Cinema Display 24'' stopped working once, I found out it was the mainboard and I replaced it—I also replaced the power driver as I had one, but the error was in the mainboard. It's been working fine for 4 days and now, again, the same error, the backlight doesn't work.
A day after the screen stoped working I noticed the backlight had dimmed a little bit. Also about ten minutes before it stopped working it smelled a bit to "burnt chip".
Probably a new board will solve the problem but the source of the problem is elsewhere. Could it be the fan stopped working and I didn't notice it?
Is there any fuse in the main board I could replace so that I don't have to buy all the mainboard?
