I have the exact same issue and I've contacted Zenith about my problem. I have checked all available resources and tried many things to try to fix the problem, but they've all failed. My computer is not the problem, either, it works with all my other TV/monitors including my 50" plasma (though I never use it for the computer, due to the burn-in problem) I've even tried adjusting the resolution on both the TV and computer to resolve the issue, with no progress. It seems to be a Zenith problem, my NAXA (generic) and VIZIO have no problems running the computer. They start right up every time.
