Is it really the inverter board?
I've read many questions, answers, etc. dealing with display inverter problems, whereas in most cases the display beacklight wasn't working at all or was flickering because of mechanic problems.
So I have almost the same problem with one difference: in general my backlight is working, but only at lowest level. As soon as I light it up with F2 button, it breaks down. If I bring it back to zero (with F1) and then 1 up, it comes back.
When the laptop wakes up from being closed before, it usually as well breaks down and needs to be resetted to lowest level (as explained before).
So I'm curious whether this could really be the inverter, as most people say that a bad inverter causes completely dead backlight. And it doesn't seem to be a mechanic (cable) problem, as it has nothing to do with the screen angle. But: sometimes when resetting it from 0 to 1 it is flickering and crashing then again, so I have to try the described routine for 3 or 4 times until it works.
Meanwhile I already opened the macbook to check if I can see any cable damage or loose connectors - nothing.
So what do you think: is it really the inverter? Or, as it seems to be dependent of F1/F2, rather software? This is a 2 GHz Santa Rosa machine.
THX a lot in advance for any help!!
Is this a good question?
