MBP Screen Flickering Black
On a MacBook Pro 2017 A1708 with function keys.
Past few days the screen has been flickering on/off constantly, occasionally just portions of the display has black bars that flicker.
It flickers every few seconds by itself, or more rapidly when i'm typing/moving the cursor.
Weirdly, it stops flickering when i check for updates, or have it hooked up to an external monitor. This i guess indicates it's either software issues, or hardware? The usb c ports maybe? Idk. The ports work for charging, ext monitor, and mouse still, although it has been having issues reading usb drives/ext. drives.
What i've done to try mitigate this, but to no avail:
- boot in safe mode, reset smc and nvram/pram
- updated from big sur to monterey
- replaced the battery (needed to anyway) and inspected insides, nothing unusual from a glance
- disk utility first aid
Any help/clues would be much appreciated.
MacBook Pro 13″, macOS 12.5
