2003 Sony Trinitron KV-32HS510 video issue

vert height, vert centering maybe? you could go up on the height 1 or 2 digits and see if stabilizes. i think it might called vert sync. its your sync in the vert not being in sync with the Sega. had to that back in the day with tube sets and early hybrid and solid state, so it could be used with a VCR. let me research it and get back to you.

I did find VLNL and VLNH in 2170D_5. Idk if that's it though.

Google is your friend:

Manual:
https%3A%2F%2Fdiagramas.diagramasde.com%2Fotros2%2 FKV-34DRC510.pdf (first hit with a google search for the Service Manual part number, 9-965-937-02)

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!)

I downloaded the service manual yesterday. Don't see vlin anywhere. The tv is a 4:3 tube. It's not the wide-screen model.

Ok I figured it out. Using 2 and 5, I went down to VPOS, the using 1 and 4, I went to VLIN. Here I a couple hours, I'll connect everything again and change the vlin 1 or 2. I'll update after.

Ok, I went in to VLIN which is default at 9. I went down to 7. No change. I went up to 11. No change. I don't know what's going on
