Thank you for bringing this to our attention. Try the following:
• Test on second source, if it’s happening on all sources it’s likely not the external device
• Test new connection cables, if brand new cables are having the same issues it’s likely something in the TV
• Test the picture test (Settings > Support > Self-Diagnosis > Picture Test) If it’s in the picture test then it is 100% something in the TV
• Ensure firmware is up-to-date, on the Samsung.com support page for most models you can find the most recent version, to have the cx check with this version, match it to the software version found in the menu under Support > Contact Samsung
• Test a reset of the TV before offering service repairs. (Settings > Support > Self-Diagnosis > Reset > Default PIN 0000)
