I have a BC 7007 and a BC 7700. I think these are a lovely piece of art. Together with those I have som hand held remote controller

the  Beocenter  terminal TYPE 2043 (Not the same as for 7000 and 7002 and not the master control panel)

Problem nr 1;

One of those have the problem that when you push a button a little green switches on, but it do not switch off after pushing the button. This means that it kind of freezes and burn out the battery. The terminal is in nearly mint condition outside.

Question. Anyone who have a simple sollution to this? 

Problem 2

 The other terminal only works for about half of the buttons. Question: Is this possible to get in order?

1. will probably have a stuck button. Make sure that all buttons make a distinct little click when pressed.

2. will probably have cracked solders. You will have to open it to see if that's the case. Could also be defects in the PCB tracks or a chip at fault even if that is rare to see.
