We are currently using a Memorex MLTD2622 flatscreen TV at my place of employment in the client waiting area. It seems that there is a screen saver set of some kind as the TV will automatically shut off after a period of time. This is a feature that we would like to disable but haven't been able to figuer out how to do so. I can't seem to find anything about it in the manual, can someone help us out with this? Thank You
