Hi there guys and gals. I am attempting to fix a countdown timer that I recently purchased. It uses 7 segment displays for day, hour, minute, and second. It ws originally used as a countdown timer for the year 2000.
It lights up and counts down, however some of the 7 segment displays seem to have a loose connection or a broken somehow. They work on occasion when pressed or slightly twisted but are not reliable to display correctly. All the soldered connections look good but there is definitely something going on.
Anyone have any experience with these things?? Thanks and I hope to get a chance to explore more of this great site.
