Summary

27" curved Trinitron from the late '90s. Similar to the KV-27V42, but with buttons on the front panel instead of the top. The V series TVs were sold as premium models, and include features like side mounted speakers, extra A/V inputs, A/V monitor output, and velocity modulation.

Notes

Two higher end version of this TV, the KV-27V45 and V65, were also produced. These models featured an extra A/V input and Picture-in-Picture.

This TV, along with other higher end Trinitron models, includes a Velocity Modulation feature. While this can help improve picture quality and reduce composite artifacts with video content, it fares poorly with pixel art and can have a detrimental effect on game graphics. It can also be disabled by disconnecting connector CN942 on the neck board. This is a 4-pin connector with a short cable that runs to a coil on the neck of the tube.

The jungle chips used in BA-4 and BA-4D chassis Trinitrons are very versatile, and these TVs can be modified for RGB and/or Component video. The RGB mod procedure is very similar to the KV-27S42.

Composite 240p Performance

by Eli Krause

For composite decoding this set uses the Sony CXD2073S, a 2-line digital comb filter used in many models from their 1997-1999 lines. As with all 2-line comb filters, the amount of dot artifacting added to 240p content is severe. If the set has an AA-2D chassis, then the set's own internal notch filter can be enabled in the service menu - NOTC 1, which will avoid the horizontal dot artifacts caused by the comb. If the set has a BA-4D chassis then there is no service menu option to enable the notch. But if the set has an s-video input (or if it has been modded for component input, or if one does not want to toggle a value in the service menu when switching to and from using composite), then using a good external notch filter to decode composite instead, and sending that to the set would properly blend all dithering patterns and avoid nearly all dot artifacts. Guide to using an external notch filter with a CRT is here.
