Don't lit, isn't powered, it's an effect camera flash.
Yes are isolated from chassis, you can't see because is transparent isulation.
Not, the problem is in minus rail, the 5 leds between mosfets don't lit & the 2 resistors 33 ohms 1W in parallel starting smoke, as you can see his colour is different of positive rail.

I thought they were some strange color. OK, so are the leds facing correctly? There is a guide sign. A half circle. Showing how to orient their flat side.
Mines are round, yellow colour lit, when don't lit are transparents.

Yep. The 240's and 9240's aren't the other way around for sure? That's a board, few things to go wrong.
merlin,
do you have the ground jumper between the diodes installed? from the pics it looks to be missing

I should mention I've done neither to these boards. But I did both to a couple of F5 boards. Have a hard time reading P vs N. Oh ya, and no ground reference for baby shunt killed that. Can't win or lose if you don't play. It's called experience right?
@igwt
I didn't, thank you😱
@Tea-Bag
So I have to change two 9140 rail minus, anything else more?
@Salas
Do you know who's the seller....

We need one of those magnifiers with white leds on the rim. Simple tools that can help a lot. I got a 3Euro thing with pivoted braces, a couple of crocodiles at their ends and a magnifier on another brace that can be positioned around. Its very Metropolis. Can hold for you a small board to assemble. Only 3 Euro and it can save a lot of nerves.
Where it says IRFP240 you can use either that or IRFP140. On line sellers, electronics downtown shops.
As far as it shows those must be your main mistakes. Change the BBQ resistors too. PCB seller is someone Passphile. 😀
Without mistakes life will be too worried.
Ok connected gnd, it's necessary to change the 2 mosfets for rail minus?
