If that is your box, then the earth ground wire in the upper left corner appears to be broken at the lug connection.
Also some of the electrolytic capacitor appear to have puffed up tops, e.g. C701, c705, c706
Have you determined that your control board has a failure of some sort, or are you just throwing parts at it?
A failed control board is very rare in the list of failures of OBC, most failures are in either the AC Input section or the HV DC Output section. There are a few outliers that have resisted all efforts to repair, but in theory it should be possible to repair the OBC boards.
It's most unlikely that anyone has a complete board spare.
There is also another board with way more electronics on it under this one. Have you checked the small capacitors in the DC output section that often fail?
To inspect the lower board, you need to disconnect a ribbon cable. Check the instructions linked from the index for how to disconnect this connector without damaging it.
