Boots to blank screen, no image or backlight, external monitor works
Having some issue with my 2019 not showing an image on its display. It boots normally and touch bar is working but i am getting no signs of life from the lcd. Backlight is not on and there is not image even when i shine a light at the screen.
The weird thing is if i boot it and then connect an external monitor nothing happens, however if I boot it while the external monitor is connected the backlight comes on(still no image) and the external monitor then shows up like it normally would.
Another thing I noticed is that under display settings when the external monitor is connected, it only recognizes the external monitor and not the internal/main lcd of the laptop.
Just curious if anyone has had a similar issue and if im looking at a bad lcd or bad board.
Ive already tried smc/pram resets as well as reinstall of macOS and even revive via another mac with no changes.

Hey just wanted to give you guys an update. I have another a2141 16" that is a fully working. I took the suspected bad display and swapped it onto that laptop and the faulty display turns out not to be faulty. Works perfect. So the issue is forsure not the display but rather the board. Gonna have to do some more investigation
Is dit een goede vraag?
