A Pressure Damage MacBook Pro Screen can happen when the display is squeezed by a packed bag, an object left on the keyboard, or pressure applied while the lid is closed. Common signs include dark blotches, colored lines, bright spots, or crack-like marks beneath the surface. Physical panel damage usually cannot be fixed with software, so avoid pressing or flexing the screen further. Back up your data, check whether the display works normally with an external monitor, and contact Apple or an authorized repair provider for an inspection and repair estimate.
