Lightning port not functioning properly

The front left lightning port on my macbook air seems to not be functioning right. I have a dongle with an external monitor and a wired keyboard attached through it. the keyboard works fine. But, the monitor no longer will work off of it. If i turn the monitor off and back on it will work for a few seconds then quit again. How can i fix this?

Macbook crashes when disconnecting from LG monitor Hi, I have a re-occurring issue with my MacBook and external LG Ultrafine monitor. Quite often, when I connect my MacBook to the monitor, I get a picture but the MacBook will not allow me to put audio through the monitor or use the built-in monitor video camera (neither show up in System preferences or any of the apps I use such as Teams, Zoom, FaceTime, etc). At this point, if I disconnect the monitor, the fan in the MacBook will fire up and then the laptop crashes and requires a reboot. The display is connected to the laptop via a USB-C cable. I know this is quite a specific issue, but interested if others have had similar experiences?

Mini Display Port Stopped Working (MacBook Air) I have a MacBook Air (2015) plugged into an external HP Monitor via Mini Display to HDMI. It worked for a year and has just recently stopped working. If i restart the computer a few times and do the Command + Option + P + R reset it sometimes works, but not every time. Any suggestions to get the mini-display port working properly again?

Mac Studio M1 MacOS Ventura 13.5.2 not detecting USB-C monitor AGAIN! I have two Benq monitors of different models. One connected via USB-C and one via HDMI. After updating to MacOS Ventura 13.5.2, Mac Studio stopped working via USB-C monitor AGAIN!!!!!!!!! This always happens with major MacOS updates! Clarification: Mac is able to detect the monitor via USB-C. The monitor is shown in Display Setting BUT no image is pushed to the monitor via USB-C!!! Monitor: BenQ SW270C Connection: USB-C detected but monitor is not receiving graphics; HDMI detected and working. Tried: Restart PRAM System Setting, Display resolution reset, Detect monitor. Called Mac Support. Gave the usual "oh I am sorry to hear that but there is nothing I can do to directly solve your issue...". Safe Mode: Not tried as it does not work with Logitech bluetooth keyboard! And I will so disappointed to pull out my vintage Mac USB keyboard only to find that it is a waste of time because someone in Apple forgets to resolve a long-standing bug with USB-C monitors! Anyone facing the same issue, do chip in. Anyone with a work-around solution, please share here.

Hi,

Try to run Apple Diagnostics if it reports something related Thunderbolt hardware errors(NDT001 to NDT006).
