Summary
The most affordable 20" from Sony's 1996 product line. The S20 added stereo speakers, the S30 added a front composite input & audio out jacks, and the V60 added S-Video and acoustic chambers for improved sound. Set pictured has an S-Video mod.

Notes
The default sharpness level is such that it causes ringing; to mitigate, lower sharpness signifcantly. Also, like on many consumer sets, gray balance was skewed blue and can be corrected by lowering BCUT in the service menu. AXIS and DCOL affect general color balance.
On the set pictured, the S-Video mod incurred mild chroma dots when CROM (chroma trap) is turned off (set to zero) in the service menu. This suggests Y/C crosstalk somewhere in the circuit, so I left CROM enabled (set to 1). This will make hard edges slightly softer, but will remove the chroma dots. This setting has to be set to off for composite regardless.
