I advise you not to play with the main board, the way you are playing with 100$ breakout board. This taking it out and bringing to a guy... If you dont know what are you doing better dont touch it. I know people that have f%%%d things just by touching them not in the proper way. if you dont know how to handle sensitive equipment especially true. I have sold 1000$ board perfectly working here, luckily confirmed with video, which guys f^^^d up on the other side by not knowing how to handle it.

So i am starting to have a headache from what you say. At least make sure yo have discharged static from yourself and transport it in a anti static envelope / any pc repair shop will have that from GPU or similar . One other thing particularly disastrous for boards is to try to measure them while connected and touch sth that you should have not touched and especially disconnect sth when board is powered on.

You need electronic engineer or similar, not electrician! Apart from that you have to explain him exactly how the board is supposed to function so he understands where the problem could be.

You have to be very lucky if its only the PSU after yo handled it. I dont see how you will repair the board if it has ICs that are custom programmed in factory.

On other side everything can be repaired, luckily this machine is quite old, maybe repair will not be more than cheap element so just start finding an industrial repair solution for this board!

The most important thing is to analyse with cool head if that board has just simple elements or it has an element that could be preprogrammed with software. My local guy for example have repaired me a VFDs for which i was quoted into the hundreds just to look at it and here it cost me 15 euro.
