Marantz 4400 Scope Tuning misaligned FM mode

Dear sirs,
I made the recap in a Marantz 4400 and the equipment is excellent in several points. The Scope that did not work well is aligned and responds perfectly.
There is a problem that occurred prior to changing the capacitors that I can not resolve after recap:
In the SCOPE Tuning or Multipath function the alignment using the FM source is 0.5cm to the right of the center alignment, horizontally according to photos.
In the SCOPE Tuning or Multipath function the alignment using the AM or Aux source is correct for the center alignment, including the "X".
Where can I make this correction? I'm having trouble.
The STEREO light works well, the intensity changes so that you can see it vertically.
I would like a hint how to align this detail.

Thank you very much

Guys, I found the fix.
"RT09 is the DC bias adjustment resistor that corrects the position of the unsigned point"
After this moment, everything was fine. Thank you very much
