I'm trying to set up my Roku Express to a 2005 Sony WEGA KLV-32M1 television which doesn't have an HDMI outlet on the back. I used a HDMI converter that connects an HDMI cable between the ROKU and the converter. The output of the converter has 3 wires (Red-White-Yellow) that I then plugged into the back of my TV. When I have the ROKU up on the screen, there is a vertically jumping picture of the start-up screen. It's more like the screen is rolling upwards rather rapidly. Help!
