Pressure damage on MacBook Pro screenMacBook Pro displays are thin enough that pressure on the closed lid — a bag with a charger inside, a hand leaning on it, something left between the keyboard and screen — pushes the layers of the LCD together.Not fixable — new panelHeat damage on MacBook Pro screenHeat marks appear as yellowish or brownish tints, faint blotches or a warped-looking area, usually along the bottom edge above the hinge where the machine runs hottest, or wherever the lid was left closed on a hot surface or in a car.Not fixable — new panelMacBook screen pressure damageApplies to MacBook Air and MacBook Pro alike: the display is a thin LCD or mini-LED panel bonded to the glass, and any point pressure on the closed lid leaves marks — dark blotches, lines, colour shifts — with the glass intact.Not fixable — new panel
Warranty: dead pixel policy by brand.
Not sure which one you have? Open the full-screen test, step through white, black and grey, and match what you see: a mark on every colour is in the panel; a mark only on light colours is a shadow on the backlight; a bright spot only on dark colours is a loose backlight reflector; lines that change when you tilt the lid are the cable.
