Looks like the Canooter valve went out

on a serious note I checked all of the soldering joints, they look fine

I am wondering if it is a blown cap or sometht

You may have to remove the transistor clamps.

I see nothing obvious. The good thing is that there is no extensive damage so it is worth repairing.

Without better photos it's hard to really see anything. Based off of those it looks just fine.

Grab a digital multimeter, set it to continuity check (audible beep) and check for continuity between gate, drain, and source legs of all mosfets. Keep in mind that occasionally there will be a beep that will go away after a few seconds. That's normal as you're charging a cap somewhere in the circuit.

Smoking usually indicates a power supply fault so it's best to check there.

Also don't freak out when the rectifier diodes show continuity, that's normal.
