My MacBook Pro recently screen slowly turns black and has overlay of whatever the windows are on the screen even though it is minimized. However if I use external monitor the external monitor shows without error. Tried following methods but still NONE are working. Check Mac’s BatteryRestart MacRestart Mac with Specical KeysReset the NVRAM/PRAMDisable Suspicious Login ItemsSafe boot Firstly it was completely black. Then after restart a few times, it only shows the top bar
The screen then slowly recover line by lines but still have the overlay issue. Here’s a video of it. https://drive.google.com/file/d/1G-8awwX…
Then I shutdown the MacBook for a day and it works fine after that. However the screen slowly turns black again with some horizontal and vertical black lines if I leave it on playing some youtube music. May i know how can I fix the root issue and how to prevent it?
You need to get to an Apple Store or authorized service center to get your system fixed ASAP! Depending on when you bought your system and where your warranty coverage could expire very soon if not already! Your display assembly has failed! And you need to get it replaced. Its quite expensive so you really want Apple to pick up the costs here. Don’t let this slide! OK the why! I suspect your displays T-CON board overheated because the vents where blocked or the fans failed. So the needed cooling was not available. Using a good thermal monitoring app like TG Pro can be helpful in watching things as well as allow you to trigger the fan to ramp up when things are getting toasty!
