The "white" ceramic precharge resistors have been splattered with soot from the control board AC Input section detonation. There is a simple test to determine if they are intact--measure resistance in the Neutral path thru the power board to the waffle plate™, ~10R.
Speaking of, it would be good to see if the waffle plate is okay or not, i have an OBC that needs one and others will too, so don't throw it in the trash. Member coulomb has a nice diagram for checking the WP,

i can see that this board has had the AC Input X2 capacitor changed in a previous repair (located just below and left in your photo showing the toroidal EMI filter inductor.
Also it looks like a repair was done for the blue M&Ms--with the yellow spray foam filling in the gaps around the little blue snubber capacitors in the fenced area.
So repair attempt(s) were made previously, but either something wasn't connected back properly, or something not repaired, or some hellacious electron bolt came blasting down the AC.
Is the input fuse on that control board okay? What about the Spark Arrestor near it? Can't tell by looking but didn't appear to do their job. Same with the black lollipop ZNRs transient suppressors. i would rather see them blown than the board, they can be replaced.
