HELP!!! This morning I turned on my tv and the screen was blue with these curved lines going across it but I could still see the picture. Then, about 5 minutes later the entire picture went blue with the lines across it. I turned it off then back on. The tv came on for about 3 seconds with no sound or picture, then it shut off with about a second of sound but no picture right before it went completely off. Everytime I turn it back on it does the same thing. I pressed the reset button but that didn't help. I'm in dire need of help. Thanks!!!
