I have a 2005 Durabrand TV and recently lost the remote control. I need to press the tv/av button in order to watch dvds but I can't because the button is located on the remote control. Can someone tell me how to switch using the menu button? I have searched myself but haven't had any luck. I know that I can just buy another remote control, but I am trying to do it without the remote. Please help! Model # BH2004D
