Nanao MS8-29FSG, Convergence or Geometry issues?

[christian776]

Hi all, I have a Sega Astro City with a Toshiba monitor and a Nanao MS8-29FSG and I have the lower parts of the image a bit curved (is this called bowing?) and I was wondering if this is fixeable by moving the yoke, as it seems to be too much for a convergence issue, but I might be wrong.

Lower parts? Looks like it's bowing in the middle. Is it bowing on the bottom of the monitor or on the side? I can't tell if the photos are rotated or if the monitor is in tate.

Take a picture further back that shows the whole monitor.

Maybe H. STAT? (Reference to the beams misaligned)

Here's a picture of the cabinet, I should have said it's in TATE mode. About the H.STAT

, I'm not sure I've seen that pot on the chassis.

You need to realign the yoke and / or add magnets to fix that. Likely the latter.
