    As I understand it, if you lay a plasma tv down flat, you will ruin it. Try googling the problem your having (and provide some more details). My information is sketchy and second-hand at best, so don't take my word for it.

    No picture and sound together, usually points to a defective power supply, or there is a failure on one of the other boards and the power supply is in the protect mode.

    These sets are normally serviced by doing board swaps, as just like servicing a computer. In some instances the new board may require some calibration. For this you would have to consult the service manual. You will also require the proper test and calibration equipment to make the adjustments.

    If the set is more than about two years old, replacement boards may no longer be available. Call the manufacture tech support for proper and accurate information.

    remove the rear panel and check all cables and connectors this was a common fault with these models at one time

    From the fine folks at Wal*Mart who won't take one back if the tv has problems during transport from the store if it breaks and is in this position.

    Trying to find an authoritative source on the issue, though.

    well any glass sheet will break if dropped even that on a LCD panel ;)

    so its not a plasma screen thing ... and its the jarring or dropping that is the problem

    for normal good use and care taken in servicing laying it flat isnt a problem :)

    Good to know. The only reason I asked that though was because I took someone's word for it (their reasoning was the gas leaks out, good to know that's an utter myth).
