Is my display dead?

I was using my Macbook connected to a Dell P2219 monitor using usb-c hub and hdmi cable without closing the internal display(at lowest brightness). But the display turned to blue/purple and mostly black after I unplugged all the cables. It stays the same after few hours and only works normally for external monitor. I already tried to uninstall some possible applications, update the system(but still 10.14.6) and reset the NVRAM, didn’t work.

The T-CON board over-heated killing it. This often happens when the back vents are blocked. The heat sink heat transfer fins are very close to the T-CON board as Apple moved it into the main case to thin down the display lid.

The problem is you can’t replace the T-CON board its self you need to replace the entire display! If you still have AppleCare+ coverage I would let Apple fix this as that would be the cheapest repair. If its not covered here’s the part you’ll need:

We don’t have a guide for the 2018 model but the process is the same as the MacBook Pro 13" Touch Bar 2017 Screen Replacement.

Dan, do you have any additional info on the heat failure theory for the T-CON? I have a display that failed -- backlight is DOA, but the video signal is still good enough to drive the machine with a flashlight up against the screen. I look forward to any ideas or data you might have. Thank you.

If you can see a faint image on the display you just have a backlight power issue within the main logic board, not a display/TCON issue
