Apologies in advance if I've posted in the wrong section- the forum "makeover" is new(to me). I have a Macbook 5,2(2009) that has the blank screen problem, sometimes it does work for a short bit, just long enough to get my hopes up. :-(
Troubleshooting
After removing the bezel around the screen and this piece, I inspected the wires visible at that point. I don't see any pinched or frayed wires, and moving the screen does not cause any change, either way.
I bought and installed a replacement power inverter for the display, and found no difference at all.
So, I either have a bad display, or a failing graphics processor on the logic board- yes?
Any suggestions before I sell this MB for parts will be muchly appreciated.
