Hello, i have a MacBook Pro A1398 Late 2013 with no image and no backlight. I discovered that the LCD connector on the Logicboard is working fine with no shorts. However the LCD Connector + Cable on the Screen is blown. It seems that the 2 connectors are identical. Is it possible to replace the Connector on the LCD or is the LCD probably bad from this?

Here are 2 Pictures of the Cable and the LCD Connector. The last 3 Pins on the right Side are bad and in the Cable the left ones too. I will buy a LCD Connector and a new cable and try replace them. A new Screen isnt worth the cost (for me)
The display cable is replaceable on its own. Its a bit tricky! Here’s a teardown of the display MacBook Pro Retina Display Teardown. You only need to take the display fully off MacBook Pro 15" Retina Display Late 2013 Display Assembly Replacement to then slide off the clutch cover to gain access to the cable and its connector (Step 5) after removing the antenna assembly. Theres a bit of tape covering it which you’ll need to peel up to pop the retaining bar (same as the logic board side) Retina MacBook Pro 13"/15" Hinge Left - Display Cable (12-15) P/N 818-2882 Update (01/18/2020) Before you try replacing the logic board connector how about first cleaning the corrosion damage on the solder joints on the left side (side with the arrow)
