Playstation, and its various cognates
Repairing consoles is hard for some. We find it easy, but in an odd kind of way, gruelling. Ultimately, it's rewarding - almost as if it's some kind of video game in itself.
The main things that fail or get damaged on most consoles are the power supplies, sockets/ports, hard drives and optical drives, we can repair most of these issues economically just give us a bell for a price anytime.
