In this video I replace the automatic switch that appears to burn out. I've completed normal testing of my transformer which is good. The issue is the common solder joint that burns out on the back of the board. You can find other videos or websites that cover how to re-solder that one pin that seems to burn out. In this video I talk about what I'm replacing. I replaced the switch because I've re-soldered it several times now and it continued to fail after a few months of use. This is how I was able to replace the switch and fix the board rather than buy a new board.
Sorry if you get dizzy or the audio is a bit low, my first video just using my phone.
