Identify what actually turns off
If you are looking for a Geo IPTV sleep timer setting, first identify what stopped. Did the entire Apple TV turn off after roughly the same interval, or did only the programme stop while menus remained available? Note the time you started watching and whether someone intentionally set a timer. A repeated interval is useful context, but it does not prove a subscription or network problem.
Inspect the one-time countdown
Apple documents a one-time Sleep Timer in Apple TV 4K’s Control Centre. Hold the remote’s TV button, select Sleep Timer and inspect the option shown. To cancel an active timer, select that control again and choose Cancel Timer. This countdown is different from General, Sleep After, which concerns inactivity. Follow the controls on your actual model and software version; do not remove a household member’s intended timer without asking.
Keep the result specific
After an agreed timer change, return to the same player and observe one ordinary session. If the device stays awake but playback still stops, report that separate symptom rather than calling every interruption a timer fault. Include the Apple TV model, player version, approximate stopping interval and whether Home Screen navigation worked. Keep passwords and private playlist addresses out of screenshots. Avoid a factory reset for a timer check, and retain sleep preferences that serve your household.
