Update: The problem seems to be intermittent: now the LC2 is working, stabile 5V and both IR and touch is working properly. Took some ref. voltages to compare when it (probably) will stop working again.

Note: Some components seem to be changed before (the usual faulty capacitors and the PWM IC).

Many thanks for the reply! I think I start with searching my own stash with old manuals and see what I find, otherwise It’s time to make some more measurements and see what I can find out that way. The other LC2 is still working and I can compare values with that unit, altho it need some more efforts.

Hey!

New to this forum, great to see so many B&O enthusiasts! I have a LC 2 light controller thats served me for several years but now it needs my attention. Initially it had an intermittent problem and didn’t turn on from time to time. Now it’s not responding at all. It got power in: 230 volt and out ca 226 volt unloaded and after load it drops to 10-16 volt. I would really appreciate if anyone have a schematic so I can study the design and not do the usual “guessing-game”. I’m suspecting the caps but before I just random recap the electrolytics, a schematic would be a gift from above 🙂

All the best

Johan
