Solved Monitor Won T Stay Illuminated Unless I Open It Very Wide Or Narrow Macbook Core 2 Duo

Chosen Solution

When I am using my MacBook white 2008 with battery or ac (not a power issue), the monitor needs to be in one or 2 very specific positions in order to make it light up. I think it might be a switch in the hinge or something. Any advice?

sounds to me like it’s your inverter cable. see this guide for replacing it.

I agree with pierrej, if you can still dimly see the desktop when it goes out. Here’s my guide on that: MacBook Core 2 Duo LCD & Inverter A1181 (fast method) Replacement If you can’t see the desktop, you will most likely need to replace the Display Data Cable. We need that serial number.
