Hi Keith
Many thanks for all of the information on the LC2, I have now got a better idea of what I am dealing with and the following is now clear:
The dome, the spiders web and the small plastic tube are all important in the touch control functionality. Since that is working OK, I shouldn’t be having any problems with those items.
The IR functionality is most likely going to depend on the performance of the small IR receiver PCB. It is therefore possible that my problem is related to some faulty components on that board.
I have had another look at the LC2 internals and the packaging that came with it and have found the following:
I cannot find a “Type” number written on the LC2 but assume that it is 2130 for the EU market. I am not sure what your Type 7406 refers to.
All of the three packaging boxes have the same “model number”, 1213125, but I don’t know if this helps at all.
The earliest serial number from the three units is 14708428 and this might be useful for identifying whether some of the production changes have been applied or not.
The PCB appears to be fitted with two diodes at right angles so, from your description, this could be a reasonably current model.
I don’t have a PCB serial number that I can see but it might be underneath.
In your text to me, you mentioned that the cable to the IR receiver is brown, green and white. I cannot find any cables with that sort of colouring anywhere.
The IR receiver PCB seems to be joined to the other board by three heavy pins. I am not sure whether these just pull apart or whether I need to unsolder the pins from the top. Do you know the answer to that one?
Today, I contacted our local B&O agent and asked them to get a price for the part that you specified, 1740665. I assume that this refers to the updated replacement for the IR receiver PCB. Apparently their computers show that this part is not available, discontinued or something like that. Is it possible to check on the systems in the northern hemisphere and confirm that the part number is valid and the part is still available. If it is, I will need a contact to help supply it.
I have certainly learnt a lot about LC2’s over the last few weeks. Thanks for the invaluable help and I hope that we can continue to try and get this unit working once again.
I wanted to attach some photos but it seems that this is not an obvious task. I will have to work on that one.
