A few months ago, the bottom left corner of my display faded to black, I'd open and close the display and the display would flicker and the display would re-light. A month later it would come back and this time it was permanent. but I could still read it. Until another month later when I was traveling the laptop must have bumped into something and the entire screen was blank / black. First thing I did was to check whether the problem was the computer or just the display so I pluged the HDMI in and it works, and I also checked the VGA port and it worked. so I know it is the laptop display. 

I bought a Ribbon cable for the screen, which is NOT the ribbon cable I plan to modify. I was also thinking about replacing the screen entirely but, it was a bit too pricey for me, it would cost me between $90-130 with shipping and brokerage. So I just repair the damaged ribbon cable. (There are two ribbon cables that go into the screen, the one that you are repairing is not detachable from the screen.)  

So what did was follow these instructions to remove the display on the laptop:

I got the repair idea from this blogger:

to repair the ribbon cable that has a 90 degree bend that causes the traces to be broken and cause the screen to go blank.

Tools you need:

- X-acto knife, small phillips head screwdriver, solder, fine tipped soldering iron, 30 gauge hookup wire, tweezers (if you have big fingers.), teflon/electrical tape, and (if you want to test your connections) a multi-meter.

Without removing the clips:

clips still on.


After removing the clips, I put the display on the keyboard:

So there are basically there are two ribbon cables, the detachable ribbon cable is on the left in this picture held by tape. After removing that, you can detach the display. The ribbon cable on the right has a 90 degree bend in the cable from the screen to the connector on the circuit board.

So here is a close up of the repair and taped up to securely fasten the repair. I made sure to tape around it  to ensure no shorts are present. This is very delicate because traces may be broken or shorted if you are not careful: either with removing the insulation, soldering or taping down.
