I bought a 36" Toshiba HD upgradeable set 36HFX72 from Bernies this weekend and love the picture. However, there is a "slight" curvature in the vertical and horizontal images on the screen. It's especially frustrating when watching letterboxed dvds because the letterboxing has a 1/4" bow from the edge of the screen to the middle. Since I bought this set just a few days ago, I could wrestle the beast back to the store and have them reorder (it was the last one) or I could have a service tech work on it under warrantee. I called the closest tech & he questioned how "unwatchable" the set truly is if there's "only" a 1/4 bow to the horizontal lines on the screen. Basically, I was told (over the phone) that if he couldn't correct the image from the service menu then he'd take the set back for 2-3 weeks to work on. Since this is our first TV over 27" and our first flat-screen, are my expectations too high, or am I being taken for a ride? Do all flat-screen TVs have slight picture geometry problems, and if so, shouldn't they be able to correct them from the service menu? Would I be cutting short the life of my set by letting a tech open it up?
