@jimmydean sounds like your TV screen has developed solarization issues. Post some images of what your screen shows with your question. Use this guide [guide|21499] for that so we can see what you see. This could be a T-con error, Main Board or panel failure. If your on-screen menu is normal but your video screen is distorted, it is most likely a bad Main board. If both the menu and the screen are solarized in appearance it is either the t-con board or the panel.
sometimes the t-con board is interchangeable but this will depend on what model your TV's are.
