Plenty of faulty LED displays reported on the forum.  How reliable are the actual LED segments?  I ask this because 41years since I made an LED clock from "Practical Wireless"  that has been in use every day since. Touch wood, all the LED segments are perfect. A lot of the Beocenter displays are only on for part of the time and I would expect them to last a lot longer than 41years.

  My Beocenter 7002 has one segment that does not light but only sometimes. I suspect a bad joint or most lightly a crack in the pcb,  I will investigate if ever  have to open it up again.
