Firmware controls how a television operates, including its menus, picture processing, connected services, and some privacy-related functions. An update may add options, change how existing features work, or alter the way preferences are stored. In some cases, a setting may return to a default value. In others, the option remains unchanged while a new system behavior affects what users see.
What Can Go Wrong During a Firmware Update
A device may operate without any visible problem before a firmware update begins. Buttons respond, connected functions work, and stored settings appear unchanged. An update introduces a different situation because the software controlling the device is being replaced or modified while the hardware remains in place.
