Hi @bravo6,
We regret hearing about this experience. We'll do our best to assist you with display issues on your TV.
Have you already tried a system reboot by going to Settings > System > Power (skip if this is not an option) > System Restart? Also, may we know if the audio you were referring to is the TV audio or an external audio device attached to the TV?
If the system restart doesn't fix the issue, kindly proceed to perform a factory reset on your device. This support article will guide you in doing so: Factory reset your device.
We hope this helps. Please keep us posted.
Sincerely,
Janadee
