...or, rather, headaches!

I'm a rank amateur with electronics, but I sometimes get really lucky and narrow something down to where I can figure out what's wrong. 


Fixing it is another issue.

Trying to do my own repairs is a challenge given my skill level, so it gives me a great deal of satisfaction--and a huge surprise--when I'm able to affect a repair.
