Why does my tv have colored lines and streaks running up and down my tv screen and sometimes it leaves shadows
Cindy Reisig that could be a bad panel, a bad main board or a bad t-con board. You will have to take some pictures of what your screen shows and post those with your question. That will allow us to see what you see. Use this guide Adding images to an existing question for that. Also, please verify your TV’s model number.
