I am trying to complete multisim troubleshooting problems, and I really have no idea how to!

That is the website you get the problems from. Chapter Four. Problems P04-58 thru P04-61.

I am supposed to type up results of how I found the problem in each circuit (if there is any).

I would be eternally greatful if someone could help me with this. My grade depends on it.

Thank you.
