Hi,
I have a StudioWorks 20i with a small problem. Originally it had a
pincushion problem )( image on 1024x768 resolution.
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
are about half the width as the other ones. I occurs only on 1024x768
resolution. All other resolutions are fine.
Any suggestions or schematics available ? Thanks in advance.
