My digital audio keeps dropping out on my PIO 563A while watching movies. I know its the DVD player bc I have switched it with my previous DVD player. In order to get audio back I need to turn it off and on. I kept it on top of my reciever (Pio 45THX) and I think the heat coming off the reciever caused some internal problems (melting something??). What do you think? Will they fix it if it's within a year or will they tell me it was my fault?
