I have recently restored a Beogram CD50 to working condition again. However, there is one issue left that I've not come up against before and am not sure on how to go about solving. A couple of the LED segments are not working. I've removed the display board and red number cover. The surface mount LEDS look like something I've seen out of the Beomaster 8000. Anyone repaired (replacement surface mount LEDs?) one of these before?
