A firmware update can resolve common issues such as: Boot Loop : TV gets stuck on the loading logo. System Stability : Fixing random crashes or freezing. Performance : Improving the speed of the user interface.
: If the TV boots up after the update but still acts laggy, you can perform a factory reset via the Service Menu by lowering the volume to zero and holding specific button combinations.
