probably not on video games consoles alone, but you probably could if you fixed electronics in general(ie TVS, DVD players, etc)

I don’t imagine you’d make much money from fixing strictly video game consoles as you would void manufacturer’s warranty by opening the box. You could get a job with the manufacturer (or contacted company) that will allow you to be certified to work on said systems.

However in order to learn how to repair broken systems, you would need to take many courses in basic and advanced electronics which will allow you to expand your capabilities well beyond repairing just consoles – that would be where you make money.

you could do that as a job but most people wont want to send there consoles to a new comer (thats how business is) you could take that class just in case your console messes up or one of your family members or friends

not very much money, usually warranty covers most consoles and other times parts cost more then buying the console new.

That’s actually a good idea……
