Did you have experience about this kind of problem related to caps? I think that the chassis had 10/15/20 years of use so it's normal that caps ar...

Are these the same flybacks used on a MS2931/MS2933?
Sorry, i don't know but i think the nanao chassis had other flyback specs. Maybe the experts tell you more.
