Antenna source not found

[Scarlettdvm]

I have had my Q TV for 2 years or so. I have a wired outside antenna that has been hooked up to the TV then entire time. Until recently it worked well. Now it is saying "source not found" on and off. I have changed the coaxial cable to a new cable that I verified worked on another TV first. Other TVs in house on same antenna are working well. Is the coaxial input going out?

More than likely it's a bad coaxial cable that is the cause. Not too much troubleshooting you can do on the television itself for this type of issue asides from re searching channels and then ultimately trying a factory reset. But Factory resetting the television will cause you to loose any settings you have set up with the picture of smart hub things - https://www.samsung.com/us/support/answer/ANS00077524
