I have a 32" Sony Wega that is 12 days past warrenty. Problem is I cant change the channel and if I touch the volume adjustment. It runs to loudest and stays there. If I hold the button to reduce the volume it will run back down. As soon as I let go of it it runs right back up to full volume. After its on the The remote no longer communicates with the TV. IS there some sort of mode that I can hold buttons down while powering it on that might possibly reset this back to factory defaults ? I'm hoping thats all I need to do. Thanks in advance !!!
