Screen flashing

My smart tv started flashing from black to the picture and then to black.  It happens very quickly. I have audio.  Is this possibly a backlight issue?

    grammy531, it possibly can be. Try changing to another HDMI input to see if the problem continues.

    Can be related to the backlight but service would be needed for a proper diagnosis.
