Having read the thread about the BS9000 with SW/HW problems, I thought I would share a funny story, that might be able to do some help on other systems..
I bought an almost free BS3000 that was totally dead.. The IR diodes for the doors was lit, that was it, no red light, nothing...
All voltages to the processor was fine, and no fuses was blown.
I knew a guy at B&O, and I asked him if it was possible to get these processor boards still, but no, they were not available, however, he would take a look in the scrap, to see if there was something that looked like it.
He came back with 3 processor boards with the same factor and connections as the BS3000. First I tried to swap both memory and SW module from 3000 to one of the "new" boards. Behold..... the BS3000 woke, but with funny blinking of the red LED. The unit worked, but every once and a while, it would not turn on and the red light would blink.. The PIN Code was not available in the menu, and efter 14 days, the unit just stopped working. Apparently there is a 14 days counter build in in these units, that kills them if there are mismatch with the PIN setup.
Oh well, pulled the cpu board and replaced with another "new" board. This time I only took the SW chip, and not the memory chip, and the plugged back in. The unit started again, normal blinking behaviour AND the PIN code menu is available. I can add and disable the PIN code as needed, and the unit has worked since..
The funny story...... When tuning radio stations for the first time, I noticed that the search and switching between stored stations, was faster than normal.. Had a crazy thought, and went into the service menu, and took a look at the type code.
My BS3000 is now a Beovision 7-32 :) At least the CPU board and processor is...
So.... in conclusion.. I think B&O actually has developed generic CPU boards for a wide range of products, with slower/faster CPU depending of the unit, and off course different SW for each product also. But somehow they are "compatible" with each other..
One thing though, the PIN code functions are very secure, and they will transfer "code" between the CPU and SW/Memory chips, so this swap I did, will probably only work with boards where the PIN has been disabled.
All this is on your own risk if you try, and maybe I have been really lucky, but I have a very very fast BS3000 with the type number of a BV7-32 :)

Hi
Can you post some photo of that spare part ?
Thanks

Here they are in very high resolution :)
Thanks :)
Which of the three is the one that actually works to BS3000 ?

The one not shown, as it is in the BS3000 ;)
One of these are the original defect one, but they seem to have the same numbers, just different revisions. If you look at the image with the back's you can see the number..
I was so baffled that it worked, that I forgot to mark the defect one :(
The 3 sockets are for the SW and memory chips, and the processor itself seems to be the same, except for the version number. I need to fix the laser in the BS3000 at some point, I will take a picture of the one installed right now when I get to it :)
