[https://content.jwplatform.com/previews/eDBFUR6T-CLCLlujH|Here's a video of what's happening]

* When trying to boot, machine is stuck in cycle trying to power up
* Can hear fan and cd-rom making noise and getting power, then shutting off and cycling again in the same pattern (see video below with back panel removed)
* Cannot boot from USB (have done this successfully in the past with this machine)
* Nothing on screen at all during process
* AC Charger indicator light comes (orange or green as normal)
* Apple store gave a vague answer about power supply and wanted $475 to fix

Device:

MacBook Pro 13" Unibody Mid 2012
