Product Description
For consumers who want an HDTV that keeps pace with fast-action
movies, sports, and game play, Sony BRAVIA V-Series Flat Panel HDTVs
combine Full HD 1080p performance and Motionflow 120Hz technology for an
amazing viewing experience. Motionflow 120Hz takes both high-definition
and standard programming a step further by increasing sharpness and
detail in fast-moving images for more fluid, natural motion. In
addition, BRAVIA V-Series HDTVs use proprietary Image Blur Reduction
technology to further enhance the
picture for even better performance.
The HDTVs also feature BRAVIA Engine 2 technology, which uses exclusive
Sony algorithms to reduce visual noise and sharpen and enhance an
already-striking dynamic contrast ratio. Additionally, they include
seven versatile HD connections to ensure you get impressive image
quality from all your HD components. Take advantage of four HDMI inputs,
component and composite inputs, and a PC input, as well as a USB input
that lets you play audio files from USB storage devices, or connect a
compatible camera to your HDTV for a quick and easy slide show. Sony
knows your home theater set-up doesn't stop with your HDTV, which is why
the BRAVIA V-Series HDTVs are compatible with BRAVIA Link Modules --
including the BRAVIA Wireless Link, BRAVIA DVD Link, and BRAVIA Input
Link Modules (all sold separately). The HDTVs also support BRAVIA SyncTM
technology so you can control all of your compatible devices with a
single remote. And all BRAVIA HDTVs exceed ENERGY STAR 3.0 requirements
for in-use and stand-by power consumption, meaning you don't need a lot
of power to get a lot of performance.

Editorial Reviews
Review from Home Theater Magazine
Review from HomeTheaterMag.com: Sony Bravia KDL-40V5100 LCD HDTV

The Sony came in a close second in the judging.
Two members of the five-judge panel voted it first overall, and two
rated it second. No one really disliked it. I can't say how I might have
voted had I been participating blind, but I like to think I would have
placed it on top, given my partiality to serious viewing in a darkened
room and the resulting need for great black levels. As I noted earlier,
the Sony also won raves for its performance with the lights on--although
that was a very short part of the test and not included in the scoring.

Customer Reviews
Excellent TV, Auto contrast can now be turned
off!
First things first, THEY FIXED THE AUTO-CONTRAST! I have nothing but
good things to say about this TV. Do not be fooled by the 1 star
ratings. All those 1 star ratings complain about the auto
contrast/brightness feature which could not be turned off, but SONY
FIXED IT ALREADY in the newer units or a software upda
te via sony.com
will add the controls to turn the function off.
With that biggest gripe fixed, this TV has outstanding visual
clarity and the color saturation is beautiful. Black levels are
excellent on this non glossy screen. You can't go wrong with a Sony and
the software update shows they are listening to their customer base.
No dead/stuck pixel, great viewing angles, 120hz refresh is great for
sports, but in my opinion, not for movies. Excellent TV, I would buy
another one of these without hesitation, superior when compared to the
other brands that offer the same features. The Bravia V series lives up
to the Sony name and quality standards you would expect. Deserves all 5
of the stars it's rated.
Excellent TV
Update May 3, 2009:
My original review of the TV was negative due to a problem of
dimming during dark scenes. But few days ago Sony released a software
patch to correct the problem and it worked for me. Now, the auto
dimming can be turned off by setting the "Adv. Contrast Enhancer" to
Off. Also, even when it's turned On, it doesn't behave like it did pre-
patch, it now dims gradually rather than abruptly and it doesn't dim as
much as it did before. Thank you very much Sony, I'm updating my
rating to 5-star.
I'm very happy with the TV now that the auto dim is fixed. If you
own the TV and having problems with the dimming, go to the support
section of Sony's site to download the patch and the instructions on how
to apply it. You will need a USB thumb drive formatted in FAT32, but
if you don't have it, Sony will mail you one if you call t
heir customer
support.

Original review:
Date: April 8, 2009
Rating: 2 stars
When I purchased this TV few days ago, there were no reviews here
since it's just been recently released into the market. I, however,
looked at the reviews of the previous model (KDL-40V4100) and didn't
find any serious complaints so I went ahead and purchased this TV. I
regret my purchase and will explain why.
This is my third LCD TV -- the others are early generations LCDs
from Sharp and Sony and they are still working great, but they are no
match for the picture quality of this new Sony. There are a lot of good
things about this TV and I would have given it 5 stars if not for one
serious flaw.
The TV dims during dark scenes. And sadly it doesn't do it
gradually, it happens abruptly 6 seconds after the start of a dark scene
and it returns to normal lighting abruptly about 0.35 seconds after end
of a dark scene. It seems to happen regardless of the source of input
(I tested it with composite, and HDMI) and it happens on broadcast
channels and cable and regardless of the "picture mode" and other video
settings. There is no way to disable it. If you're watching a movie with
lots of dark scenes, it's going to be a very annoying experience.
Take this example, while watching a documentary on first gulf war,
there was a lot of night vision camera scenes and the TV keeps dimming
during the lengthy dark scenes and when it does that, you can barely
make out any details even with Gamma set at max. The dimmer kicking in
and out is annoying by itself, much less the picture quality when it
dims.
I contacted Sony support and they seemed clueless and recommended I
initiate a repair request. I did an internet search only to discover
many Bravia models suffer this problem. I initially thought I had a
defective unit, but now I think it was intentionally designed like this.
Very disappointed in Sony
We bought the V5100 2 weeks ago. After getting it home we were a
little disappointed with the picture as we didn't have HD yet, so we got
the HD dish installed. Picture on HD was perfect, other channels good
but not great. When watching DVD's we noticed the dimming issue, dark
scenes getting darker and darker. After reading a few review sites I
discovered there was a fix from Sony so I called the customer support
and asked to be sent the software update. That took about a week, and
the USB would not download, it went to a blue screen. So I called tech
support and got a guy that was really clueless to the problem. He had
me call a not so local authorized dealer which wouldn't come out, we
would have to take the TV there, 40 miles away, drop it off then have to
go back another day to pick up!! So, I decided to try to download the
fix myself from the Sony website. After a few failures I discovered you
had to format the disk to FAT32, so I did and it worked. But it hasn't
fixed the dimming problem, it's still there just not quite as bad. The
store we bought the TV from tried to work with us saying it might be
that our DVD player is not the newest or best, but I'm not sure that's
an issue. We have decided to take the Sony back and get a Samsung or
Mitsubishi. It's disappointing that Sony would sell TV's knowing there
is a problem, and then not tell their retailers that there is a known
problem. Or at least the store is claiming they didn't know. They are
willing to replace or exchange it. I'd be afraid of the same problem
with another Sony. Very frustrating.
Update: Went and compared the 5100 to the Samsung and did not like
the Samsung as much. So asked the store to send technician to adjust,
haven't heard from them. In the meantime after much research on
different websites I discovered after you do the software update you
have to set the Advanced Contrast Enhancer to Low or Off, I set at low.
And, I set the picture setting to Standard, not Vivid, altho Vivid was
brighter but maybe not better. Now it seems perfect, no shadows or
shading in the dark scenes. So for now we are happy campers, hope it
stays that way!
