Notes

Unlike the 27" and larger BA-5 Trinitrons, this TV does not have native component inputs. However, its jungle chip is very versatile and can be modified for RGB and YPbPr component video. Please note that due to a different M board design and jungle chip, the RGB mod procedure for the 27" BA-5 Trinitrons doesn't apply.

S-Video mod instructions

The user menu includes a tilt control. To have a warmer color temperature closer to reference 6500K, in the service menu section VP2, set DCOL to 0 (instead of 1).

Composite 240p Performance

by Eli Krause

For composite decoding this set uses a Toshiba TC90A49P, a 3-line digital comb filter. Depending on the console/revision, dot artifacting ranges from slight to severe, and blending effects may be broken. If the set has a component YPbPr input on, then using a good external notch filter to decode composite instead (such as the one in a RetroTink) and sending that to the component input would blend all dithering patterns and remove nearly all dot artifacts (full guide here). A recommended no lag HDMI to component converter is available here.
