> I have a StudioWorks 20i with a small problem. Originally it had a

> I replaced a few components in the E/W circuitry (IRFS640, MTA114,
> 150nf/250V cap). Picture width and E/W is fine now but the horizontal
> linearity is not. On both sides the image is a bit compressed for about
1".
> I mean if you put on a test screen with squares the ones on the screen
edges

> resolution. All other resolutions are fine.
>
> Any suggestions or schematics available ? Thanks in advance.
