I have been using this cable for quite some time now. Tonight, I watched "Batman Begins" using it and then turned off and unplugged the PSP. About an hour later, I figured I'd pop on another movie. Plugged it back in to the PSP and heard the PSP's sound coming out of the TV speakers as usual. BUT, when I tried to flip over to TV mode this time, the PSP gave me the "No A/V Cable" error. Unplugged and re-plugged, and same deal. Then, I tested it on one of my other PSP's (I have three) and it was the same deal. The cable apparently just "died" for no apparent reason. I checked over all of my connections of course (nothing had changed) and my TV settings were exactly the same.
I drove out and grabbed an official Sony component, brought it home, and I am back in business again. But this is somewhat concerning. WHAT would make a cable just go "bad"? In all of my years using a multitude of cables, I have never experienced something like this. Does anyone have a clue as to what happened here?
