Can anyone help with this problem that im having, or have some suggestion on what can i do? When i turn on the the tv it stays on for about 5 seconds and turns off. While it's on the screen looks like the picture is trying to focus then it shuts off. What i figured out is if i continue to change the chanels, (about 15 times) the picture restores itself little by little till' the picture looks fine and then the tv will stop turning off. Does anybody have any idead on what the problem is.
