The signal keeps coming and going at random. it might stop a minute after the last time or more than an hour, and for a random time. Sometimes I get the message `check Signal Cable.’ The TV has gone off completely, with only the error messages showing

Hi, Don’t know about the TV switching itself off when losing signal but regarding loss of signal in general check the following:

  1. Ensure that you have selected the correct antenna input source in the TV. See p.38 of the User Guide.
  2. If you are in a weak signal area try enabling the Low Noise Amplifier in the TV. See p.42 of the User Manual. Here is a link to the User Manual for your TV. http://downloadcenter.samsung.com/conten

With digital TV the source is either good enough for a picture or not. they don’t get fuzzy or noisy like old analog sets. A very marginal signal would have the picture go on and off as you describe. Check the things that Jayeff described and if you use cable then have the company send someone to check the strength. Some cable boxes/DVRs have a signal checker in the setup menu (Comcast X1 for example is under the Gear icon > Comcast Labs > Signal strength).
