That's for the DA-4, multiple models.
Most Sony CRT sets have the same data acronyms:

VFRE Vertical Frequency
VPOS Vertical Picture Position
VSIZ Vertical Picture Size
VLIN Vertical Picture Linearity
VSCO Vertical Correction
VCOM Vertical Compensation
VUSN Shrinks Vertical Height to 16x9 Area
VZOM Places Bars on Picture to give 16x9 Area
EHT Adjust Height of VZOM
ASP Vertical Picture Size - Aspect
SCRL Vertical Picture Position



Can't stress this enough - write down ALL initial values before making any adjustment. Note the range of values too - and don't go above or below. If you do, you may briick the set, as Sony used the DAS device to recover/restore EEPROM data. Without it, you're gonna be SOL if you corrupt the EEPROM

Also, on the HD CRT sets, try the customer menu setting for aspect first - don't try to feed a 4:3 with a 16:9 aspect selected (or any other movie aspect ratio!)
