Random Boards Section

If you complete all 100 trouble shooting boards, that doesn't mean the troubleshooting challenge ends. The Random Board Section, as the name implies, selects boards at random. Each board is disguised with the same title; "Random Board", so you won't be able to recognize the fault by title. When you make a correct diagnosis, your pride and self accomplishment will be your only reward in the very challenging Random Board Section.
