Chosen Solution
I’m Trying to fix a Unibody MacBook, late 2008 ,13 inch , 2ghz. The backlight goes out on the display when it warms up. Backlight will come on briefly after power switch is pressed for a short bit. Works great on external monitor. Have replaced heat sync temp sensor, replaced entire screen with known good one. It acts like a capacitor issue. Do any of you know the location of the capacitor that triggers the backlight on this motherboard? And if so would you kindly share the info? Thank you for your help @oldturkey03 @Stefano Gigante @mayer @danj
I think you are right. I have the same machine and it has the same problem. My case is a bit different. When my Mac first behaved that way? I followed up and found that my LVCD fuse blew and so I had to buy a new fuse. I did this twice and still the fuse kept on blowing and so I decided to short with a wire. this time round the display worked for some times and went off when the machine warms. I’ve been thinking the problem ever since and I think you are right. it can be a capacitor issue. let me try to see if I can find the capacitor itself
