Hi Ricky, Thank you for reaching out to us regarding the screen issues you are experiencing. Please try these troubleshooting steps to resolve your issue. 1. First, let's run a cold boot on your TV. To do so, hold down the Power button on the Samsung TV remote until the TV turns off and then on again. This should take about 5 seconds. 2. Confirm that the TV is set to the same source as the external device. For instance, if your cable box is connected to HDMI 1, set the TV source to HDMI 1. If the TV is set to the correct source, but there is still no image, unplug and reconnect the AV connections one cable at a time from both ends of each cable. If there's any damage to the cable, it will need to be replaced. After reconnecting the external device, please turn it off and back on. 3. Test the HDMI cable. The test is designed for HDMI cords less than 6 feet long and may not give accurate results on longer cords. To perform the test, make sure the TV's source is still on the HDMI setting for the cable you want to test, and then navigate to Settings > Support > Self Diagnosis > Signal Information > HDMI Cable Test > Start Test. If the test says the cable is bad, replace the cable. Service is not required. 4. Test different external devices. The final thing to rule out is the external device you're using. Try connecting a different device or using a different source port. If the TV can display a picture in any other setup, then you've ruled the TV out as the cause of the issue. Keep trying various setups until you identify the device or cable that is not working and troubleshoot or replace it. 5. Please run a Picture Test to determine if the problem is caused by the TV. Picture Test displays a high-definition picture you can examine for flaws or faults. Go to Settings > Support > Device Care > Self Diagnosis > Picture Test.
