Sony KDL-40BX420 Review – 40-inch LCD HDTV


There is not much to talk about this TV as it can only serve as a basic set for watching the normal TV programs. It neither has 3D nor the Internet TV, which are the most-sought features of this year. But since after buying a huge 3D set for your...

Sony provides 5 HD inputs in the TV which includes 2 HDMI. If you consider that this is only a basic TV which will only be a second set in the house, you may not need to connect too many high definition devices to it. However, if you want, you can...

Solid picture performance ; Light, easy to set up ; Customizable picture presets ; Decent sound

No Internet or network features ; Thicker bezel than some ; Less than perfect blacks

BRAVIA BX420 is great


I had issues with the color on initial connection. 20 minutes later, it was perfect and no problem since. Sound is low volume-wise so I hooked it to my stereo, all good! Everything else works wonderfully. And for the price, it's awesome.

Energy Efficient, Good Remote Control, Great Picture Quality, Easy To Setup
