Vertical lines, coloured bands or horizontal stripes across your MacBook display? iFixMac diagnoses whether it's the LCD, the display cable or the logic board and gives you a single clear quote.
Lines on a MacBook screen are almost always a hardware fault on the panel, cable or display-driving stage of the logic board. The exact pattern of the lines tells us where the fault sits — and how to fix it.
Fine vertical column lines mean a cracked LCD or pressure damage; thick coloured lines mean a driver IC fault; horizontal bars suggest backlight or GPU output; hinge-angle lines mean a cable.
MacBook Air and 13" Pro displays develop lines from closed-lid pressure even when the outer glass looks perfect. Internal LCD replacement often fixes this on supported models.
Movement-triggered lines point to a worn display cable. Lines on an external monitor too indicate a board-level GPU fault — fixed by board-level repair.
Same-day repair is often available when the panel is in stock. Newer Apple Silicon Air and 14"/16" Pro panels may need to be ordered.
Most often a cracked or pressure-damaged LCD. The outer glass can look perfect while the LCD layer underneath has hairline damage.
Sometimes — when the cause is a cable or board-level driver IC. If the LCD itself is damaged, a panel replacement is required.
The fault is on the GPU or display-output side of the logic board, not the panel — a board-level repair.
