    Enhancing geometry on old Sony PVM 1440QM

    Hello all. I have this monitor. Recently it died due to a bad cap , the c606 400v 330mF in the power board. Replacing that made it wake up again.
    The last days I tried to set the geometry by tinkering with the internal potentiometer and some 240p test suite pattern. No matter what I can't get a perfect straight line. Since that cap went bad I am thinking maybe I need to replace some others for enhancing the geometry. Could anyone help understand which ones ? Here is the service manual . Thanks
