I have a friend using the s-video connection on a PS2. When a dark scene in a DVD movie comes up, the signal drops off completely to the TV. He has swapped-out the TV, swapped-out the PS2, and swapped-out the Monster cable. He has even taken the PS2 and the cable to the vendor, and connected it to the same model TV at the store-and it works fine. Composite video seems to work fine. TV model only has the one video input. He has even had en electrician test the circuit. Has anyone experienced this, or, does anyone have any thoughts as to what this could possibly be?
