How to read Sony model numbers?

[kx250rider]

It changed a few times, but basically for consumer-type TV sets:

First two letters are the Product type; i.e. KV=CRT color TV, KD=CRT color digital TV, KL=LCD TV, etc

Second two (numbers) are screen size

Up 'til the 2000s, the next two (or three) numbers are the actual model version.

Suffix letter(s) indicate extra stuff: R-remote, S=cable-ready tuner, X=has video/audio inputs, T=stereo tuner, and on 1960s-70s models, "U"=USA-only model, etc.

So a KV-2680RS is a 26" set with remote & cable-ready, but not stereo.

Then they swapped the order of model number and features suffix, so it gets confusing. KV-27SXR10, for instance, is a 27" CRT set with cable ready, remote, and video/audio jack panel. (by then, they stopped adding a "T", since stereo was standard).
