Some users report that Apple service centers call this malfunction irreversible, offering a screen replacement as the only solution. However, since most iMacs experience this problem after two years, the warranty on the device has already expired, and the screen replacement will cost $600-700.

Despite numerous reports, the manufacturer has not yet recognized this defect as a manufacturing defect and has not released any official comments or solutions to fix the problem.

One user discovered that the iMac screen uses a flexible cable rated for 50V at high screen brightness. Eventually, this causes the connector to overheat, causing short circuits and black bars. Even after replacing the screen, the problem may reappear after a year or two.
