Hi this just started, the monitor has thick lines that run through the screen, after about 20 minutes they go away. Picture is then normal. I don't think it's a monitor issue, because when I unplug the video to the monitor it looks normal. Maybe power issue or pcb?, please advise. See attached video link. The Lines are much larger than the video now, yellow sometimes covers entire screen. Thanks!
