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.
