Summary
The last of Sony's 24" CRT models, the 24FS120 is a follow-up to the 20FS100 and 20FV300. Introduced in 2004, it was produced until 2006 when Sony's consumer TVs were phased out (although several larger Sony CRTs were introduced in 2005 and 2006). It's mostly the same as the KV-24FS100, with the addition of a 16:9 mode.
Literature
Notes
A common problem with Sony's flat CRTs is horizontal bowing, especially near the bottom edge of the screen. This is usually caused by poor yoke alignment, and can be corrected. For more information, see the "Adjusting a Flat CRT Yoke" page.
Like the other BA-6 chassis Trinitrons, this TV uses a one-chip design and cannot be modified to accept RGB. However, its component video quality is excellent.
The remote control in the picture is from a flat panel TV and is different from the original. Sony has used the same remote control codes since the 1990s, so modern remotes will still work on these TVs.
Disabling Velocity Modulation
Most of Sony's flat Trinitrons contain a velocity modulation circuit. VM enhances dark outlines on screen, which helps hide composite dot crawl and can make TV and movies look better. However, it ruins pixel art and significantly degrades the appearance of 2D games.
In this model, turning off VM in the user menu does not completely disable it. To address this problem, go to the service menu and set "VMOF" to zero.
Composite 240p Performance
by Eli Krause
For composite decoding this set uses a Renesas M65582AUF, a 3-line digital comb filter/unified jungle chip. The blending of dithering patterns is inconsistent, and the dot artifacting is severe on all consoles tested. Recommend using an external notch filter to decode composite instead (such as the notch filter in a RetroTink) and sending that to the set's component input to remove nearly all dot artifacts and blend all dithering patterns.
