I just need to know how to get my ECCO tv's AV setting because the remote doesn't work and it seems that you can only select the AV setting from the remote?

Is there some kind of menu button on the TV itself? If there is, usually you can use the volume and chanel up/down buttons on the TV to navigate through the menu and either the input button, some other button, or the menu button as "enter." Or there are a lot of menus where you just use the arrows, or in this case the volume and channel buttons to navigate and you don't have to press "enter."
