Hello. I tried searching, but couldn't find anything on this. I've had my Samsung ln52a860 for around a month now and just today it started taking substantially longer to display a picture after switching between an HD channel and a non HD channel. At first I thought it might be my Directv receiver causing this, but it also happens when I change sources on the tv. It has gone from around 1-2 seconds to sometimes 8-10 seconds. Does anyone have any ideas as to what I might able to do to remedy this? Thanks in advance.
