We bought a 40XBR two years ago to replace our Sony CRT TV -- we are dinosaurs in this age of flat screens. We thought that the 40XBR was great but we wanted a 2nd TV in our guest room. We did some research and decided on the 46EX620 -- a LCD backlit smart TV, a later version of our 40XBR. Our 40XBR is relegated to the guest room and the 46EX620 is our main viewing TV. The factory direct imagery is great. We spent additional monies to have our 40XBR color tuned but this expense was not worth it and did not do this with the 46EX620. 46EX620 imagery is natural, balanced, sharp, clear, and crisp; a real pleasure to view. We congratulate Sony for 10 bit A2Ds and their imagery enhancement software.
There are two issues. One is that I can't get my ancient DVD/VCR player to play audio with VCR tapes -- might be time to get rid of my VCR...
Second issue is streaming NetFlix. The 46EX620, much like the 40XBR, has a "load" issue with NetFlix where the TV hangs (pauses the stream for a few seconds# and then continues. We thought that Sony would have improved the software in the past two years, i.e. the 40XBR software versus the 46EX621 software. Our LAN connect is provided by Cox cable; we pay a premium for highest speeds #10+ Mbps are measured# yet both TVs have a hang issue. We connect my ASUS G1 laptop to the same LAN switch feeding the 46EX, connect the ASUS to the 46EX via HDMI and Audio port #essentially the ASUS is the controller# and have no problems with hangs #MS Win7, NVIDIA 7700, DVI & audio ports#. We believe that this is a SONY software issue – perhaps not enough buffer memory? We have reported this 2nd issue to SONY.
All in all, the SONY 46EX621 LED backlight, smart TV, exceeds my expectation value #$Cost versus Expectation). The SONY 46EX621 is an exceptional value and we rate it at 4.5 stars.
