Sony KDF-42WE655 Pin-Cushion Geometry

Just purchased a new Sony KDF-42WE655 over the weekend--really enjoying the screen, however--when I tune to local OTA stations, the picture initally comes up in 4:3 mode with bars on each side and I've got the pin-cushion effect on the vertical geometry on each side of the picture--best that I can measure it's somewhere between 0.05 to 0.10 inch deviation from vertical along each sidebar--I've called Sony and they say that it can be adjusted, but I was wonedering whether there is any one out there that knows what variables in the Service menu are used to adjust pin-cushion or is this an actual mechanical adjustment involving the LCD panels??


By the way--went back to the store and checked--the display model looked fine, but 2 more units they pulled from inventory and hooked up were as bad or worse than my unit??


I've seen this question asked by a few posters in this forum, but no replies.
