This is one of the most ridiculous threads I have read. As if you can't turn on something, such as a pinball machine, which can form issues by just looking at them wrong...

When I sell now, it's sold as is. Could be HUO, but it is as is. I make this clear in the email/pm with the buyer, and I tell people it's working now (or whatever the state is), play it as much as you want, take out the eye piece and look it over, but when it leaves, it and any possible issues are now yours.

The consensus of dodged a bullet is correct.
