Goal zero yeti 3000 dead AC outlet from burnt inverter board.

[Elmarinpro]

Hello folks,

I would like your advice on how to fix this inverter board from a yeti 3000.

The AC outlets does not work but everything else does.

I disassemble the unit and found two SMD chips that are burnt.

That's the only visual damage that I see.

Do you have an electronics repair shop in town? I used a local place for a board repair and it was $20. Sorry I don’t have any experience on this.

At first it’s good to figure out why blown the both resistors. They can be fuse resistors and they can blow anymore if is repaired.

Can you do straight shots of the whole top and bottom side of the board?
Those burnt out resistors does look to be fusible ressitors for feeding the V+ to the MOSFETs, you can see that they are connected to the Drain pin of one of the MOSFET's.
Moe likely to find shorted MOSFET's.
