I have a Panasonic DVD/VCR combo player. I have tried connecting to the Roku 50" TCL TV. I have tried all of the hdmi ports and the av port (which is not hdmi). I have a 3 to 1 connector with a single connector to connect to tv and i have tried a 3 to 1 connector with hdmi on the end. It still says NO SIGNAL IS IT ON?
