Hi there, Thank you for your review of the Samsung AU8000. Your feedback is important and will be shared with our internal teams. Your TV has several self-diagnosis tools built in that can help solve problems with signal, network, picture, or sound. Go to Settings > Support> Device Care > Start Device Care You may also want to clear out your TV's temporary storage space by pressing and holding the Power button for 6 seconds until your TV turns off and back on again. Please also be sure you are running the latest firmware. You can check to see what software version your TV is using and if there is an available update through the settings on your TV. Go to: Settings > Support > Software Update. If you haven't tried this already, here is another way to rescan the OTA channels: Go to TV source and go to Menu>Broadcasting>Auto Program>Start>Air. To select channels directly by channel number, press the “123” button on the remote to display the soft numeric keypad. Select the channel number and press done. Note : the channel must be scanned in before you can select it. You can find additional information here: https://www.samsung.com/us/support/answer/ANS00062206/ I hope these tips help.
