@kimrj make sure that you listed the exact make and model (LG32CS560). You TV’s issue does sound like a bad LCD driver. It is absolutely possible that gate drivers are failing on the board. The LCD driver board is considered a part of the panel and not easily changed by DIY means. Post some good pictures of what your panel shows with your question. Adding images to an existing question
