I have a new (3yrs) TV and the plugins for the input 1 are green,blue,red,red and white. I pluged them into the TV and into the DVD/VHS box and the DVD plays but the VHS doesn't. So now I've pluged red,yellow and white plug-ins into the input 3 (separate from the DVD and I can get the VHS to work but it won't show a picture; it said " no signal" How can that be? Cable is already setup. My name is Rita. Please help me. Nobody seems to know what is wrong. Thank you
