I run a computer repair business focused on fixing LCD monitors and unlocking/upgrading gaming consoles (Wii, PS3)
I find that focusing on a few areas is far more profitable that spreading your wings wide. While a general technician might seem to have more work, over time, the lack of focus will eat into your income.
To do well as an electronics & hardware troubleshooter, focus on areas that you are good at. In other words – Specialize!
