I did find on board which sits between the transformer and the capacitor has a burned up solder component called J1. I’m not sure what went there but it’s gone now.
On schematics and PCBs, J = Jack.
- Fixed part of a jack + plug connector pair.
- Typically a female socket, but could be male pins.
Just spitballing since I haven't seen a schematic or pics yet, but there's a good chance it was the power input jack for that PCB.
- It probably burned up because of the heat generated by a poor-quality, high-resistance connection.
