My Vizio VO32L HDTV10A picture shows purplish Hum-bars across the screen after the television is on for a while. If I turn off the television and back on, sometimes the normal display comes back. Any ideas on what this could be? It seems like a heat related issue.
above is the picture I get after the television has been on a while. It's frustrating turnign the tv off and on to reset the picture, especially when the problem doesn't always go away quickly...
