Time Machine recording availability and stability depend on the broadcast type, program rights, and USB storage health. It can also stop when the TV changes modes or when schedule/recording limits are reached.
Time Machine recording is only available for digital broadcasting channels. If you are watching analog broadcasting or some external inputs, the Time Machine recording option may be unavailable or may not record as expected.
Recording cannot be used for copy-protected programs. If the broadcaster or content provider restricts recording, Time Machine may stop or the recording option may be disabled.
If the USB storage device has file system errors, unstable power, or damaged data segments, Time Machine may not work properly or may stop unexpectedly.
Time Machine temporarily stores content on the USB storage device. Previously saved Time Machine content can be discarded automatically when you switch to External Input, run Auto Channel (Auto Tuning), power off the TV, start a different recording, play music/photos/videos, initialize settings, change modes, or use premium TV applications (apps).
A schedule requires a duration of 2 minutes or more. If you select Exit without selecting Complete, the schedule will not be saved. If Schedule List reaches 30 items, additional schedules cannot be saved. If Recording List reaches 200 items, no more recording is allowed.
If you switch the channel within 3 seconds after saving a new Time Machine schedule, the schedule may not be saved.
Setting: Home > Live TV
Open Live TV and tune to a known digital broadcast channel. If you are using an external device (set-top box, HDMI input), Time Machine recording behavior may differ and the Time Machine buffer may be cleared when switching inputs.
While using Time Machine, avoid switching to External Input, running Auto Tuning, launching premium TV apps, changing modes, playing media files, initializing settings, or powering off the TV. These actions can discard the temporary Time Machine content and may appear as if recording stopped.
Disconnect and reconnect the USB storage device firmly, then try again. If recording still fails, test with a different USB storage device to rule out device errors. If the USB storage has file system issues, Time Machine may stop or fail to start.
When creating a schedule, set the duration to at least 2 minutes and select Complete to save it. After saving a schedule, wait at least 3 seconds before changing channels. If you have many items saved, delete older entries if Schedule List is at 30 or Recording List is at 200.
Setting: Settings > General > Channels > Channel Tuning > Auto Tuning
If digital channels are missing or the channel list is inconsistent, run Auto Tuning. After tuning completes, return to Live TV and test Time Machine recording again on a digital broadcast channel.
