I have a VGA input on the back of my Hitachi Plasma 42" TV, the only thing is is says 'service only' above it, does anyone know if it can be used as a standard VGA input ? If not, what is the best way of connecting my PC with only a VGA output to the plasma TV with x4 scarts, x2 HDMI and x1 S- video, using the existing equipment ? Please help ! Thanks
