Can anyone help me to get rid of he random distortion on my Vizio D55

I have a 2018 Vizio D55-f2. The tv has a picture distortion that starts at the right side but gradually spreads to the left side over time. A repair man recently replaced the main board, but I don’t know if that’s what did it. The warranty just went out on my tv and I would sincerely appreciate any assistance anyone could offer.
