Default NAP repair suggestions

Magnavox 27 inch, circa 1994
model# HD2763 C401
chassis# 27Y100-00AA

Excellent picture, bright & clear, however the OSD flickers rapidly.
ESR tested caps in video & OSD circuitry, replaced several.... the
flickering is unchanged.
The OSD is still legible .... but annoying.
What else should I be looking at here. All repair suggestions welcome.

Cobalt:
Thanks for the troubleshooting tips..... the components you identified were
all good, the fault turned out to be a barely visible cracked trace about an
inch away from Q510..... thank you for helping me to get in the right area
to fix the problem.
The OSD is now bright, clear and stable like it should be..
Best Regards,
