2003 Sony Trinitron KV-32HS510 video issue
 

Tv has a video problem. Kinda reminds me of vertical hold on older sets. Chassis is DA4. Where should I begin looking?

hook your Sega into a VCR and connect TV to av inputs and see how it looks.

Alright, I'll try that right now and update.

Here ya go. A little better but still off

is just the Sega? or does it do that with other consoles? now you can go into service menu and adjust the vert linearity to make it stable. now if you do this write down the settings in case you have to back.

The sega works normal on other sets. What's the method to get into service mode on this model

have to google it. it can tell how to get in and what each line is for. find the the vert lin line and up one or two digits. i have a Sony Vega kv-27fs120 in my closet that i had adjusted the grayscale.

Ok I'll check tomorrow and update. Ty

Ok, got into service mode and scrolled down but I don't see VLIN. Do I need to go into something else to get there?

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.

Ok, thank you

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

Google is your friend:

Manual:

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.
