Both tubes in a flourescent are flickering and won't light. Reading up

it likely to be that at fault?


Remove the cap and see. It does sweet FA regarding the lights actually
ability to work. A duff one could cause problems. It's only there for
power factor corrections.

Or swap the lamps for LEDS ones and bypass the ballast and the capacitor.
