My remote is aggravating and it is ready to go out the window. When I push one number it comes up twice on the TV and tries to go to that a channel with that two digit channel. I am not pushing it twice real fast. It also happens when my son uses it. Now it is happening when I push the button to bring up the channel list. It comes up and immediately goes away. Or if the list it on and I try to close it I push the button and it goes away but pops back up while my finger is not on the button. Now my last channel won't work half the time. Would this be the remote or the box?
