Got into this hobby a few months ago. Have never handled a soldering iron etc.
Well, the bottom sigments have been out on flash. I narrowed it down to the resistors on the master display. (thanks Clay). One of those resistors looked burned and didn't test anything. I said what the hell, i'll try to remove it and replace.
Went to the shack, bought the .022 solder as told, the wick, and the resistors. Took me all of 15 mins to pull the old one, clean up the old solder via the wick, and replace with the new. And it works.
Total confidence builder. Just had to share!
