Patent ID: 8819480

Claim:
A display apparatus, comprising: a micom which stores a system code; and a Central Processing Unit (CPU) which receives a micom code and updates the micom code installed in the micom using the received micom code, wherein, if an error occurs while the CPU updates the micom code, the micom drives the CPU using the system code, wherein the micom comprises: a storage unit which stores the system code, wherein the storage unit comprises: a boot code area which stores the system code; a flash ROM area which records micom codes for operating the display apparatus; and a check area in which a check code, indicating whether the micom code is normally recorded in the flash ROM area, is recorded, wherein the micom checks whether a check code is recorded normally in the check area at a time of rebooting the display apparatus and drives the CPU using the system code if the check code is not recorded normally, and wherein, if the CPU is operated using the system code, the CPU restarts updating the micom code after deleting the check area and the flash ROM area.
