Hi Disappointed, We appreciate your feedback regarding your U8000F TV’s performance. If you're experiencing slow apps, freezing, or lag in general response time, try the following steps: 1. Check for firmware updates – Keeping your TV up to date can resolve many performance issues: Home > left directional key > Settings > Support > Software Update > Update Now 2. Run Device Care – This tool checks system memory, frees up cached data, and closes background apps that could be slowing things down: Home > left directional key > Settings > Support > Device Care > Start Device Care 3. Cold boot your TV – With the TV powered on, press and hold the Power button on your remote for 5+ seconds until the TV restarts. This helps refresh the system.

Hi PamPam, Thank you for sharing your experience. If you've turned on your TV and hear sound but see no picture - or if the image is cutting in and out - there are a few common possibilities to consider: 1. Connection Issue – This is the most frequent cause. Check for loose, faulty, or improperly installed cables between the TV and any connected devices. 2. External Device Issue – The problem may lie with the device connected to your TV (e.g., cable box, game console). Be sure the device is powered on and using compatible video output settings. 3. TV Hardware Issue – If connections and external devices have been ruled out, the issue may be internal and could require technician support. We’d appreciate the opportunity to assist you further. Please contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun). LiveChat with an agent, along with manuals, software, and warranty information, is also available through the ‘Support’ section on our website. ~ Samsung Advisor
