Looking at your HDMI switch box left to right the first 4 light's should be lite red 5th light is off 6th light dim red but to use DVD you push silver button second from right and dim red light lights up blue, 7th light is off. To make it simple I moved all of my HDMI cables on back of tv's to HDMI 3. We're fulltime so if you want,when you're in your motorhome and have some time private message me and we'll walk trough it all step by step congratulations again and enjoy.
