Dark/Dim screen on MacBook not related to broken backlight or inverter
I recently tested to see if another compatible MacBook LCD screen was working by hooking inverter and display cable up to a MacBook that already had a working screen. Did this switch multiple times and was easily able to hook original screen back up. Now the screen on the MacBook with functioning screen is very dark after reconnecting original cables. Clearly a backlight issue but no damage to any inverter cable and wire is not pinched in hinge.Almost positive inverter cable is plugged correctly into connector but am reluctant to open the clutch cover to see if it is fully connected to the inverter. I don't believe that is the issue or that the backlight is damaged in anyway. Cleaned connectors, did reset of Smc and Pram. The brightness display is on highest setting and macbook works fine connected to an external.
Is this a logic board shortage of any kind? Near the display or inverter cables? The previously working dark screen has never been opened or damaged.
