We are having a problem with our tv. I have been using it all day and it has been fine. Had it off for about an hour, came back, turned it on, and i could hear sound but no picture. So i turned it back off then right back on, everything was fine for about a min. As i was flipping channels to see what i wanted to watch the picture and sound went out, but the tv was still "on" it showed the blue light in the corner and the picture was black, as if i was flipping and the channel wasnt registered yet. I unpluged the tv for about 5 min, and when i plugged it back in, it worked for about 5 min, then did the same thing. During that 5 minute period, the color seemed to be perfect as did the sound. Instead of turning the tv off, i tried seeing if i could turn the av1 on, so i could watch a movie, and it would turn to it, but wouldnt show picture or hear sound. Again, when the menu log came up, the picture was perfect..well the color on the menu bar was. Please help me, I have no idea what is going on with it. Thanks!
