Clay Harrell is the master, and his repair videos, though dated, are exemplary.
You can purchase DVD's from his website on every era of pinball.

Clay's are good repair videos but don't specifically address bingos. Richard Gerlitz sells a set for around 40 bucks, IMHO worth the money. I think Alan Marriage does the other one, but I've not seen it.

I agree with "okorange", the Richard Gerlitz video is excellent
I have even emailed him with a a question I had.
Since he has a Lido machine and I have a Bikini machine I thought
he may answer my email. He did, right away!!!
Can't go wrong with him

I've recently seen the Alan Marriage ones, they provide a nice overview, and his overdubs (if he says something incorrectly during the initial recording) are entertaining. I've not seen the Gerlitz, but I understand his have more direct application stuff (how to disassemble units and so forth).

Also there used to be a pair of videos called “Life After Death” you could buy from popbumper.com. The first one dealt with the repair and restoration of a Stern Meteor, and the other was a playfield swap of a Bride of Pinbot. Really great videos, but I can’t find them online anymore. Not sure if they’re still available.

Youtube has some.

Search by what you are looking for.

Jersey Jack Pinball has some that are useful for other game too. My channel has stuff for the Remakes. And flipper spacer gauge is useful for other games.
