How does the colour go wonky, do they just come out of alignment?

What would've happened if you hadn't improved it enough so the repair man didn't know that he'd fiddled with the convergence?

Why would you want captions after? Can it mess the sound up, too?

(Sorry for all the questions, i'm just curious)

Thanks
