Notes

You can disable Velocity Modulation by disconnecting the 4-pin connector CN942 from the neck board (CV board). Velocity modulation distorts the appearance of game graphics by increasing the size of black areas, as shown here.

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), 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.
