This set seems to do different things. Sometimes it will change
channels by itself. The volume up buttons cause the channels to change
and there is a continuous scrolling green number in the upper right
corner of the screen. The menu button does nothing. When it is not
changing channels by itself if you change a channel it will hold for
about 5 or 6 seconds and then change again. Has anyone seen this set
of problems on this model? Thanks, Lenny Stein, Barlen Electronics.
