We're trying to decide where in our living room to place our new 50" plasma. We live in an older house with with deep window sills, and one option we're considering is placing the TV on one of these windowsills. The sill is about 14" deep, the TV stand is about 12.5" deep. The window is long, about 5', and located in the center of one wall of the living room, so it would actually make for a great place for the TV to sit. I'm just wondering if there are any concerns about placing the TV that close to a window... Will temperature fluctuations be a problem for the set if we place it there? There is an enclosed porch (screened porch) on the other side of that window, so there is some minimal buffer against temperature changes, but not a lot. What do you think?
