Notes

A similar 32" model with this design, the KV-32S66, was also produced. It features a second A/V input and Picture-in-Picture.

The jungle chips used in the AA-2D chassis Trinitrons are very versatile, and these TVs can be modified for RGB and/or Component video.

Disabling Velocity Modulation

Most of the AA-2D Trinitrons contain a velocity modulation circuit. VM enhances dark outlines on screen, which helps hide composite dot crawl and can make TV and movies look better. However, it ruins pixel art and significantly degrades the appearance of 2D games. Unfortunately, this cannot be turned off in the user or service menus and must be physically disconnected.

Note - These instructions only apply to the following 32" AA-2D models: 32S42, 32S66, and 32V42. The 35" versions use a different PCB design that cannot simply be unplugged.

The VM circuit is located on the WB board, which is attached directly to the neck of the tube:

AA2D%2032%20VM%201

To disable it, just disconnect the cable from connector CN2941 on the WB board:

AA2D%2032%20VM%202

You can either remove it completely, or just fold it back on itself and secure it with the purse lock tie:
