Hello,
I have an old Beomaster 1700 which I love very much. But unfortunately, I got a problem with the on off switch. I does not turn on anymore.
I opened the top part of the beomaster. The white switch/actuator seems to be down and free, it does not come up back automatically.
There is a very small spring that I put out, in order to see if I could switch it manually but when pushing up the small white pin (the spring is attached to a fixed black pin upside, and to an other white pin downside, which I suppose, should move) , it is blocked (it moves one milimeter up only). I did not try to push to hard, as I was afraid to break everything...
Is there something I can do on the switch itself ?
If I can not do anything on the switch, I was thinking to cut the power cables which are soldiered to the switch, fixe them together (blue with blue, red with red), and then, put a on off switch on the cable, outside.
Does it make sense ?
Many thanks for your help.
Hi Kentaro,
I resently bought a 1600 and 1700 for parts, i think i can help you to a working switch.

Thank you very much for your proposal, Marc.
But I am not sure it is possible to dismantle the swith, without breaking other parts...
Frankly, I am puzzled:
It is quite strange: Such switch is supposed to be used many many times, and it is very lightly constructed with such small plastic parts...
It could have been made much strongly, without increasing signifcantly the price...
At that time, there was no chinese production, and people were ready to pay the price for well done things.
That 's therefore quite surprising for such a well known brand, even if the 1700 was one of the less costly of their product line...
I could understand that an electronic part would be broken after so many years, but I did not expect that a simple mecanism like that would breack...
I wonder if the other beo products were made in the same way...
my experience with B&O is that al the plastics deteriorate, become brittle and brake easy.
the switch is made up of a plastic cover and a pertinax (pcb type) plate, which are mounted together.
sometimes these come apart and you can glue them back together, if the switch is still in one piece but just stuck, i've had good luck with cleaning them good with brake cleaner and lubricating it afterward with WD 40.
Hope this helps,
