Answer to: Display MacBook Pro A1260 had a loose connectionTry pushing below the Apple on the back of the screen if the color returns your display cable probably isnt broken. It is easily fixable with some doublesided tape. Just follow the Installing display cable tutorial Without removing the cable. When opening the screen you can see the chip right next to the display connector, cut a piece of tape the size of the chip and paste it on there (between chip and plastic). That should do the job and spare your some money on a new display cable you dont need..
