Tv screen goes black and then comes back on.

Samsung TV’s have an issue with the Side power botton and channel changer of their TV’s. Try opening the Back of the TV with the power disconnected. (Use all safety precautions.), and disconnecting the side card for the internal power button and channel changer. Put the back back on plug the TV back in and use your remote and test the TV. If that fixes the issue then you are good … Just do not lose your remote….
