7z archive named Autorun, 19.4 MB, filed among Philips TV materials but with no model, board or chip mentioned, so its purpose cannot be stated from the name alone. Files called autorun are sometimes USB service or update packages that a TV loads at power-on, though this one must be opened and examined first. Check any readme or folder structure inside, confirm it targets your exact model and chassis, and scan unknown executables before running them on a workshop computer.
