Sounds like the cable is fouled up somewhere within its own sleeve. Its just going to keep getting worst. Just get a new screen it will cost around $70-100 depending where you go. Sony is a big name but their quality is terrible. They use to be good in the 80s early 90s. To me they are innovators and not a company to buy from.
oh ok, well that would really sucks, anyway do you know of a site that i can go to purchase a new connector, or lcd screen for it?
