A method for detecting and correcting an error of a device in which a malfunction of a horizontal/vertical processor used in an image display device is detected and corrected. A microcomputer initializes the horizontal/vertical processor, determines whether the horizontal/vertical processor is activated, sets an error check state for a malfunction check of the horizontal/vertical processor if the horizontal/vertical processor is activated, checks whether the horizontal/vertical processor has malfunctioned, and returns to the initialization step if the horizontal/vertical processor has malfunctioned. Accordingly, a malfunctioning horizontal/vertical processor can be rapidly converted to a normal operation state, and a damage to a product occurring due to the malfunction is prevented in advance to stabilize the quality of the product.
