Possible loose connection causing lowest dim setting?

A few weeks ago my screen started jumping to the dimmest setting (as if the backlight is no longer working) but after wiggling the screen back and forth it would come back on. Now it's gotten worse and I have to perch it up against something at a certain angle. If I move it the problem will continue. Now I have to keep it at the lowest visible setting or else it will go back to unreadable. I have found that if I put pressure on the left part of screen, just above the hinge, then it will stay lit up, but as soon as I let go its back to black if not being perched against something. Could this be a loose cable? Do I need a new backlight entirely? Help!

So would you suggest taking apart the border around the screen and repositioning it? It started acting fine every once in a while but i can fix it again by pinching that spot. If I should take it apart could you let me know how to do that?


Jeffery we will need the last 3 characters of your serial number so we can determine exactly which MacBook you have so we can supply you with instructions and point you to the correct part, if you need one.

Hi Jeffrey, welcome to iFixit !!

From your description the problem seems to be a faulty inverter cable probably damaged in the macbook left hinge. It could also be a bad cable connection to the inverter board located inside the display so first troubleshooting step would be to check the cable connections at both ends and inspect the cable skin insulation.
