I had been reverse engineering the jumper settings for a MHz display in one of my cases, but I could not get one of the segments to work. I had concluded that the segment must be defective 🙁
Today I desoldered it from the PCB (nice first job for my new desoldering station), and tested it. The segments LED is indeed not working 🙁 Unfortunately it's the middle horizontal one, so I can only make a 1 or a 7 now 🙁
I wonder if I can find a replacement. Finding the data sheet for the display unit was surprisingly easy (and very helpful).
Those 7 segment displays are usually standard off the shelf stuff. Shouldn't be hard or expensive to find a replacement 😀
If you can't find a 2 digit one, I'd guess two 1 digit ones would be fine too. The pin configuration on those displays seems to be pretty standardized.
I have been looking for a replacement last night, the pinout seems standard, and so does the voltage (if I pick the same color). Now finding one (or two) for a decent price (including shipping) is a bit harder. Replacing it with two 1 digit displays seems impossible, it has 2x 9 pins. Will continue the search today.
