Hi, frankk, Thank you for your feedback on the Samsung TU7000 regarding the picture quality and sound. Your input is important to us and will be shared with the internal product teams. To help you better enjoy your TV, we recommend trying the following troubleshooting steps to enhance your picture quality and sound. Go to Home > Settings > Picture > Picture Mode and select the mode that best fits your usage: 1) Standard: Default mode suitable for general viewing environments. 2) Natural: Reduces eye strain for a comfortable viewing experience. 3) Movie: Suitable for watching TV or movies in a dark room. 4) Dynamic: Makes the picture brighter and clearer in bright viewing environments. 5) Filmmaker Mode: You can watch the source content (e.g., movie) as it is. If the image is defined as Filmmaker Mode, it will automatically switch to Filmmaker Mode while watching. You can also go to Settings > Picture > Expert Settings and configure the image settings to your taste with additional functions. If the same problem persists, run a diagnostic test. (Home > Settings > Support > Device Care > Self Diagnosis > Picture Test). If the problem disappears during the test, check your TV signal (Home > Settings > Support > Device Care > Self Diagnosis > Signal Information) to check the signal strength. The signal strength must be more than 20 dB (more than 4 bars on the icon) for stable signal reception. Additionally, there are several sound settings you can adjust to suit your personal sound preferences. Change the Sound Mode by going to Settings > Sound > Sound Mode. You can customize the sound with Expert Settings by going to Settings > Sound > Expert Settings. I hope this helps you enjoy your experience.
