Hello all, I have replaced the broken display of my MacBook Pro 13 A1989 with an original display of the same model coming from another MacBook. The backlight of the display is super low, I can barely see any image, while keyboard light, Touch Bar, webcam, Touch ID, and so on, work great. I have tried resetting the SMC, but there was no change. Any idea if I plugged anything loosely so the display can’t get enough power, or something like that? The replacement display was working. Thank you! Here is a picture of the connection to the display:

This is one of the few cases the display cable from the logic board to the T-CON could be bad or have a bent pin/contact. Take some pics of the connections and post them here, do make sure they are in focused Adding images to an existing question Update (05/09/2021) OK the cable in question is this one pointed to in Step 19 here MacBook Pro 13" Touch Bar 2018 Screen Replacement disconnect the other side and flip it over to see the contacts and inspect the socket connections.
