Found a shorted diode in the pincushion circuit, ordered an exact
replacement part and installed it. Pin is now fine however it appears
the image is a bit too large, I'm not sure yet how large but when I
change channels the very edge of the text runs past the edge of the
screen. Pic looks good other than this fault, nice and bright with good
color.

Is there a common cause of this? I almost wonder if the EEPROM got
slightly corrupted though with everything else working fine I'm worried
that a fault may still be present so I hesitate to adjust anything.
