    When I connect my Acer Aspire laptop to my Westinghouse HD TV the picture is ok but. there are two big lines that go up the tvs display continously. I believe that it is a electronic noise of some sort, How can I stop this?

    TIA, bigedsm

    It might be some type of a grounding issue. With the laptop disconnected from the AC adapter and nothing else (wired LAN, speakers, printer, etc.) connected to it, do you still get the moving bars?

    I realized I left out one detail in my first post.

    It should have said with everything disconnected from the laptop EXCEPT for the TV video connection, do you still get the bars?

    If the bars go away then there is most likely a grounding problem between different devices connected to the laptop. Start reconnecting things until the bars reappear and let us know the results.

    If the bars are still there, exactly what kind of connection are you using between the laptop and TV and how long is the cable?
