I am trying to connect a PS2 to Yamaha DSPAX750 amp then to a Pannasonic plasma screen. There is a joint component/sound lead from the PS2 into the DTV input on the amp, then a component output to the plasma. The sound works fine when the DTV option is selected, but there is no picture on the screen, it says no input signal in the top right. I also have a DVD player connected via component, this works fine. I have tried the PS2 compenent lead in the DVD input, and it still doesnt work. Is there something I am doing wrong? The PS2 lead is brand new, but could it be that at fault? please help as its driving me crazy!
