I've had this KP-46WT500 for 2.5 years. I loved the picture until a week ago. I organized some of the wires in the back of the TV and decided to do the Flash Focus automatic convergence again. Now the picture appears to wobble. Its very noticeable when words are on the screen or when I bring up the TV Guide. I checked all of the connections and everything seems fine. What did I do and how can I fix it? My Paradigm Mini Monitor speakers are on stands right beside the TV and are unshielded, but they've always been by the TV and this has never been an issue. My Paradigm Center speaker is right in front of the TV and is shielded.
