Summary

An excellent 27" flat screen CRT TV, manufactured by Toshiba in the USA. It is a very well made TV, and features a dual-focus tube from Philips. Includes a full set of inputs: Component, S-Video, and Composite. This is one of only a handful of 27" AF models that Toshiba made in-house; beginning in 2003 all their sets in that size would be made by Orion.

Notes

Some of these TVs use a yoke with advanced electronic convergence controls. This is great when it's working, as it allows dynamic convergence to be fine tuned. However, this also provides a critical failure point, as the TV will become useless if there's a fault on the convergence board. This feature was not documented in the service manual.

Velocity modulation can be disabled by unplugging connector P703 from the neckboard.

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).
