Here's a wee copy & paste from elsewhere:
If you're going for a Sony be careful you buy what you want. There are not so good budget versions, and better quality more expensive versions. The following should help you make sure you buy the right one:
Here is a typical Sony LCD model number
KDL46V2000U
This number can be split up into 5 different parts - KDL - 46 - V - 2000 - U
KDL
The first part tells you about the TV's tuner. KLV- means an Analogue tuner. KDL- means that the TV is equipped with a digital one and can pick up Digital Terrestrial broadcasts ("Freeview" in the UK).
46
This is the size of the screen in inches.
V
This is the series number. There are 6 different letters that you can find here (U, S, V, X, W & E).
The U-Series:
The "value" range. The bottom range, designed to be cheap and sold at supermarkets and the like.
The S-Series:
One step up. The new S-Series models (KDL-xxS2000) feature the BRAVIA Engine technology. The older ones (KDL-SxxA12) do not.
The V-Series:
This is the affordable higher end option. They have always featured picture cleanup technology. The first BRAVIAs used "WEGA Engine", but the new ones use "BRAVIA Engine". The upcoming "V2000" versions also feature the new "Live Colour Creation" backlight, which apparently produces far better colour reproduction.
The X-Series :
These are the best ones available but only come in 40" and above sizes. They take the features of the V-Series, add full high-def (1920x1280) screen resolution, 2x HDMI inputs, and 2x Component inputs. The picture quality is also slightly better than the V-Series. The X-Series also features BRAVIA ENGINE EX and Digital Reality Creation, which are both included to enhance the quality of the picture specifically for large, high-res panels.
The W-Series:
They feature the S-Master digital amplifier, 1366x768 resolution, and 1 HDMI input. They are still one of the "prestigious" Sony models.
The E - Series:
These are the Rear Projection TVs that are based off an LCD technology.
2000
This is the colour of the TV's casing and does not change the technical spec of the TV.
2000 - Grey
2010 - Dark Grey
2020 - Silver
U
The "U" suffix means "United Kingdom". Continental Europe has the "E" suffix.
Swiss Chedder... I'm curious as to why you say never buy anything with "Bravia" written on it????
