Hi there, I recently took apart my W580i to replace the housing. It worked perfectly the first time, after I installed the new housing, and the phone was like new. However, about a week later, I decided to replace the accessories of the housing (Walkman logos, camera covers, etc) and took it apart again. I reconnected everything perfectly, however, every time I try to start it up, the navigation pad and navigation keys light up, the keypad does not, and the right light effect turns a light blue. The screen is backlit, however, nothing shows up, and nothing actually responds or works. Please help me out with this problem, asap. Thanks very much.
