All pictures are on the internals to a LOTOS LTP5000D plasma cutter
My first day of powering it up I heard some weird noise and then could not get an arc to start
The front panel LED no longer comes on
I opened the box to check the power capacitors and those seemed fine
I then tripped over this part of the high frequency board that had burn marks on it

plasma_overview.jpg is a top level view
plasma_closeup shows a closer view of the part of the board that is burnt
