While having a broken machine is a pain, kiosks can be custom things and you have to get with its maker to see what spares and manuals they have.
But you tested some of the parts. What parts didn't you test? It's likely one of those parts.

Likely a power supply issue. Modern mother boards have 12v and 5v inputs, but usually one is inadequate (usually the 5v) for the load it needs to support. They don't fail immediately, but when they go, time to get a new PSU. This has happened to me in the past. My multi-meter found the problem in about 2 minutes.
