Sony KDL-EX640 review: Sony KDL-EX640


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...

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

Sony Bravia KDL-40EX640


The excitement of having online features is now just wearing off. We were ecstatic that a TV could be so much more than just a display for a cable box; something to connect to the internet and therefore the world! Now that the fiery honeymoon period...

Great connectivity ; Decent all-around performance

Not the Smart TV we want to use ; Uniformity issues again rear their ugly head

The Bravia KDL-40EX640 ($899 MSRP) is a low-end, 1080p Smart TV from Sony in 2012. We like that they are producing a cheaper Smart TV, hitting a niche audience that wants online features, no 3D, and a good television.

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 I have the 60 inch model of this tv and 3 months after the warranty expired on this TV (only 15 months...

"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

Nice TV but one audio "gotcha" got me


The TV meets my expectations for picture quality and internet connectivity, but I can't say that it really exceeds them, so I would have given it 4 stars, but because of the the problem with its audio output, it gets 3 stars.

Good picture

Fiber optic audio output fails on some sources

The picture and color is great, and the Clear Resolution Enhancer & Digital Noise Reduction improves non high def sources from streaming or over-the-air. It does a good job with quick moving action such as sports (for example, basketball or tennis) The...
