The invention relates to a self-repairing method for panel parameters, applied to a display apparatus. The display apparatus comprises a control module and a display panel, wherein the control module is connected with a non-volatile memory; the self-repairing method comprises the steps of (s1), storing at least one group of panel parameters into the non-volatile memory; (s2), starting the display apparatus for use, and determining whether repairing is needed or not by a user; (s3), when the display apparatus is started in an abnormal image-display condition, inputting an instruction to the display apparatus by the user to enable the control module to execute a repairing mode; and (s4), enabling the control module to read the panel parameters so as to enable the output image of the display panel to be in a normal condition. Therefore, the user can perform self-repairing of the panel parameters so as to reduce maintenance pressure.
