Last night I have drawn my first diagram of a circuit board.
The era of electronic devices home repair has long gone. How ever it was extremely fun to practice drawing diagrams and tying to pin point the faulty component, a thing my father used to do frequently during my childhood, spending countless hours to fix TV sets for friends or relatives.
The board is quite simple, the product is a night light which suddenly stooped working after about two months. That annoyed a lot so I decided to have a look inside.
I found out that the diode D3 on the schematic above was faulty. It's about a zener diode 1N473A which I have replaced with an equivalent bought with 0.1 euro from a local shop.
Even if it was working somehow after I have removed the faulty diode, it's now working beyond the doubt when replacing it with a new one.
Feeling proud.
Many thanks to my father for the electronic lessons I didn't pay attention during my youth and for patiently reminding me now things I have once learned and soon forgotten.
