MacBook LCD Display Issues

My model is mid-2009, A1181 2.13 GHz Intel Core Duo 2.

I have the same issue that everyone has with their white macbook display: it goes dark after a minute, but external display is fine and I can see faint traces of windows on the lcd. Close the lid, open it up, the screen is on for a second or two and then it goes dark again.

After researching other posts I have reset the SMC, replaced the back light inverter cable and replaced the inverter itself. None of those efforts helped. While replacing the inverter panel I noticed that a gray cable going from the inverter to the back of the screen was pinched, but I couldn't tell if it was actually cut.

Could this pinched cable be the issue? If so, can I replace the cable without getting an entirely new screen? After shelling out around $90 for the cable and the inverter, I can't quite bring myself to drop another $200 on a replacement screen if I might face the same issue.

Replaced display data cable and still no luck. I'm thinking the problem has to be the gray cable going from the inverter into the display. It's pinched in two places and it would only make sense that the pinched cable going from the back-light inverter into the monitor itself would cause problems with the back-light.

I can't find a way to attach photos, otherwise I would show the gray cable that I'm talking about. However, rather than open the mac up for the fourth time I might just upgrade my external monitor since the mac could give up the ghost in another year anyway.

I think the gray cable is the microphone cable. Just add electrical tape where the skin is damaged. Now concerning your backlight issue, I would check the battery connector/sleep sensor board. Check if the board is well seated in its socket. This board manage the sleep function of the display. If the board is faulty or bad seated it could bring down the backlight power. The macbook top case may also be faulty (brightness function) and cause the backlight malfunction.

I believe the gray cable is your bluetooth cable. Hook it up to an external monitor and see if the issue persists.

The pinched cable appears to be the data display cable as seen in step 50 from MacBook Core 2 Duo Display Data Cable Replacement

I'm working on an external monitor now. The macbook screen still goes dark. inverter cables and panels have been replaced.
