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.
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 2X, 5X, etc.) and sending that to the component input would blend all dithering patterns and remove nearly all dot artifacts. A recommended no lag HDMI to component converter is available here (select the bypass version).
