Got new Samsung 55" LCD TV model number LE55A956D1M a week back. The picture mode keps reverting to dynamic. I have worked out this is because it is in 'Store Demo' Mode using the info button on the remote. I now need to know how to disable the 'Store Demo' mode and change it to consumer as it keeps changing every 30 mins or so.... very annoying. Other than that what a fantastic TV - very highly recommended!
