A:Answer Hi,
To improve your F6000F TV’s response time:
1. Update firmware – Home > Settings > Support > Software Update > Update Now
2. Run Device Care – Home > Settings > Support > Device Care > Start Device Care
3. Cold boot – Hold the Power button on your remote for 5+ seconds.
4. Power cycle – Unplug the TV and any connected devices for 30 seconds, then plug back in.
If issues continue, contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat agents are also available through the ‘Support’ link on our website.
