I have or am trying to hook up my dc with a vga box.... My tv is a rca d36120 hdtv. when I hook up the vga chord to the vga in on my tv.... I get a picture for two seconds then flickers off, then on then off. But when, my picture is there its clear but not colored right (alot of greens). I then tried to hook it up to my tv via the vga-to- component cable and it never even recieves a signal. Please someone help me!!! Thanks!!
