Display freezes, fades to white, inverse, then bleeds to bluish
I have a:
MacBook (13-inch, aluminum, late 2008)
model number: A1278
The display will fade to white (almost a corduroy look) then fades more, so that it looks inverted (like a film negative), then fades more so that there is no display except a blueish screen with small vertical blue, purple and black lines - think norther lights. If I wiggle the display assembly just right I can get the display back and fully functional. Sometimes it will hold seemingly indefinitely and other times it will will be okay for a while then fade again.
I've read about symptoms like this in other threads and forums, but can't remember the cause and can't seem to find them. My memory (which fades too) tells me it's either the data display cable (or connectors) or the inverter. Both of which it seem would be a bit of a pain in the keester to replace with these new displays with class across the front and no bezel.
Also, display works on a second monitor.
Sounds like the display data cable to me not an inverter problem. Check the connector on the logic board first and see if the catch is still in place. Move the display and see if it's moving the connector to the logic board. It could be damaged where it passes through the hinge or could be the connector to the LCD. You'll have to play with it to see which.
I have the exact same issue with a 2008 13" 2.4ghz Macbook aluminum. It is working with an external monitor attached. Sometimes I can power it on and the display will work for 2 seconds or 2 hours. Mine began with a small water spill but I immediately tilted the laptop upside down to ensure no water got in. (but then again maybe some did)Apple store representative quoted me $700 to fix it but I wasn't so sure the guy new much about it. I keep reading about Inverter boards and cables going bad with the symptoms that my computer is having. Is the problem fixable? Please help... Thanks
