Hi, my TV powers on to a green striped split screen. The top part is green and black with vertical stripes (the stripes are wider the the stripes on the bottom portion). Insignia can be seen in white letters 3 times...the 3rd one is on the far right sight of the screen and wraps to the left side on the same row. There is a a white horizontal line dividing the screen. The bottom portion of the split is a lighter green with a pinstripe grayish/black vertical line. Words in yellow are displayed; however, I cannot make them out. Most times a single power cycle removes this screen and the TV plays fine. Any idea what is causing this? Is it a sign for bigger things to happen?
