Hi there, I have the same system and I am missing the same cable. Here is what I have found out. The cable we are looking for is a proprietary Sony ribbon cable. Its hard to find it at regular pawn shops or even major electronic stores. It costs about 45 dollar US to order from Sony. My advice is to look for it at pawn shops, they might have it. Another option is have it custom made, which might cost you more than oredring it from Sony. Hope this helps, Sunny.
