Conclusion: While competing entry-level models are beginning to offer bonus features such as wireless Internet access, Internet apps and sometimes even 3D, Sony sticks to its guns with the KDL-46BX420 by focusing on a superior picture, decent sound and a user-friendly interface in an attractive package. Light but well-constructed, this TV should be an easy fit in just about any room in the house.
Pros: Solid picture performance, Light, easy to set up, Customizable picture presets, Decent sound
Cons: No Internet or network features, Thicker bezel than some, Less than perfect blacks
Summary: If you don't expect the world from the entry-level Sony KDL-BX420 LCD, its picture quality may be a pleasant surprise.
Pros: The inexpensive Sony KDL-BX420 series evinced good performance for an entry-level non-LED-TV, with deep-enough black levels and accurate color in mid-bright areas. It also, surprisingly for a 60Hz TV, handled 1080p/24 cadence properly, and its matte screen is a boon in bright rooms. Its styling is clean and its remote is among the best in its class.
Cons: The BX420 only has two HDMI inputs when most of its competitors have three or four. Its color was too blue in dark areas and too red in bright areas and its screen showed brighter corners.
