Hi all, New to the group. Glad to be here. Hope some of you can ease my mind to someting I have noticed on my new TV. I am new to HDTV as well. I have a 42" Samsung HCM4216W rear projection. I am very happy with it but it has done somethng twice that I am mildly concerned about. The set will go black for about 1/4 of a second and I can hear a tiny "click" from inside (the click sounds kinda like when you mute a reciever, almost like it's mechanical). Then it will come right back on and that's it. Both times it has done this it had been on for about 3 hours and on analog cable. Is the set "doing something" normal like switching to another tuner or mode? Any advice/ideas would be greatly appreciated.
