Notes

Unlike many Panasonic TVs, this model uses a Toshiba jungle chip. Component video quality is excellent and it should be possible to modify it for RGB.

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 an s-video or component YPbPr input, then using a good external notch filter to decode composite instead and sending that to the set would blend all dithering patterns and avoid nearly all dot artifacts (full guide here).
