Midrange Sony LED TV a good value


Sony's EX640 series is one of the better deals from the company, with decent picture quality and features for the price.

The relatively affordable Sony EX640 offers deep-enough black levels for the money and commendable color saturation. The design is attractive and the menu system is easy to use

We detected a couple of uniformity issues, black areas can look blue under lights, and shadow detail isn't up there with the better TVs. The wireless dongle takes up a USB port. The SEN portion of the Smart TV interface is so slow that it's kind of a...

I have the 60 inch model of this tv and 3 months after the warranty expired on this TV (only 15 months of ownership), the picture died. I checked the Sony Support website and there were several people complaining of the same problem and there is no...

None. The picture was good while it lasted (very short period).

Pictured dies after only a few months of ownership and Sony does nothing to support

"Piece of junk"


TV screen goes off and will not come back on without unplugging it and restarting it. WiFi adapter will not work and Sony support has no answer to fix it. They can't even figure out how I can turn it in for service.

Nice picture and a good price

I love it when it works, but that is very rare. Sony support is worthless. DO NOT BUY THIS TV

After I played with the settings, I was really pleased. I turned up the brightness and turned downed the sharpness. The strange 3D quality of the picture was throwing me off at first until I found a setting called Cinemotion. Once I turned that off, it...

Great picture. Thin. Small bezel. 4 HDMIs

great all-around led tv. did not want 3d, so this was an easy choice. SD picture is 100 times sharper and clearer than any HD set that i have viewed! SD picture is almost as good as HD. HD picture is top of the line. Motion feature is wonderful.

Ease of setup and configuration
