I was watching TV - screen went blank and a now signal message appeared. I have done the following:
turned TV off and on several times - no change
disconnected and powered down the connections to Comcast signal box - it is one of the small black ones and then reconnected and powered on again
TV has power
Check the 3 other TVs in my house and they are all getting a signal

Does the tv get a picture of any type connected directly to the coax?
Have you tried a different box on that outlet to that tv and does it get a picture?
If you get a picture doing either of the above the box needs to be replaced.
If you don't get a picture then you need to double check the connection off the splitter for that line to make sure it is tight, may need to replace the splitter, or have a technician come out to check the signal strengths.
