It didn’t! But I’ve been able to get a replacement case that is in reasonable condition.
Alas I’m not having much luck with getting it working. One of the resistors on the analogue board gets super hot (R726), but I’ve not been able to work out why. I disconnected it and burned out R788 but replacing that didn’t help either. I’ve replaced the flyback, the C5404 transistor that’s known to fail, recapped most of the power and analogue board (I tested each cap and replaced all but the ones that tested 100% which was like 85% of the board. Unfortunately that’s about as far as my current knowledge takes me and any requests for assistance elsewhere has been unfruitful

Here’s the topic I have on it:

G3 AIO “Molar” issues - Flyback? Caps?
I was hoping I’d be able to figure this out myself but alas lack of experience and information available has stumped me. I’ve acquired an AIO G3 here in the UK which is in fairly good physical condition. There’s no battery bomb issues or rust, and the logic board works 100% as I’ve hooked it...

The analog board seems nothing like Apple. It's missing lots of capacitors and has an LG part number, it has no apple part number (from what I recall). Basically schools were asking for an all in one with everything ready to go so that they didn't have to purchase monitors separately. As such, they took an off the shelf LG CRT and analog board and slap it into a tooth shaped body paired with a G3 [Beige] logic board. Next time I pop some of mine open I'll take a photo of the part number. Since this was expensive for Apple and not very cost effective but more so a last ditch solution the later G3 AIO and eMac models released later on. Apologies for the extremely late reply.
