I just got hold of a non-working LC2.  I have tested it with a old fashioned 60W bulb and  it's not responding to touch or IR. Internally, I checked the 5V supply in a number of locations and it's reading about 0.5V. Login to view image I removed the main PCB from the casing and noticed scorch marks - you can see them just above the coil mounting in the picture below: Login to view image I first thought that the scorching had come from the mains supply terminals but there is no sign on the terminals or around the other side of the casing. I therefore checked the PCB and found that Resistor 1 (bottom right, next to the Zener diode) has failed open circuit.  (I checked it in-situ because one terminal is not connected to anything other than the non-connected N terminals).  According to the manual it's 5.6 ohm, 10%, 0.4W. Login to view image My plan is to simply replace the resistor and see if that cures the fault. Clearly I am hoping that this is the fault and not a symptom! Any comments/observations?  Anyone seen this fault before?

One observation yes: I've spent hours starring at non-working LC2's guts in the hope something like you've noticed will jump into me and I'll be able to repair them. After thinking it twice, I thought that even if repaired, it would be a nonsense to have to use any 40w bulb nowadays and dropped the idea. As fun and exiting it is to use B&O light control it do not worth it to me. (But I still have and use my little 6 channels magical box that Beodrives intertechno switches !)        ;)
