good evening and happy new year to all of you!!
My question: I bought a LCS 9000 remote speaker/ ampli system second hand in the bay, The system was not working, after replacing circuit br. CB1 and CB 4 / 400mA/220V T on one side of the amplifier it works, sound ok from connected BC9300 but the remote B+O 1000 has no connection to the LCS 9000 , pressing any button on it showes no reaction. Display on LCS showes sources and time / it is connecteced to Loudsp. out 2 L/R
System can be switch on pressing right hand on red transparent , mute works as well there.
Is that a known issue? (one other guy reported to me same problem with BL3500), where to start searching for the trouble? Service Manuel available?
is the problem the infrared diode? type?
Thanks for any reply!
Regards Ueli
Welcome to Beoworld!
The speaker may be set up in A.OPT 0, where it will not respond to IR commands.
To change: On the BL1000, press LINK 4 and then STORE. Then see if it works.
Hi,
if option setting shows no help then it's most probably a SMD capacitor on the IR / Display / Touch-Sensor Board:
See here, i had the same problem once. It's fixed now :)

Option 4 isn’t the best option... that means you have to press LINK before any command!! Try Option 6 instead.
I am not even sure the first generation lcs9000 is option 4 compatible??

^ Thanks Søren!
I agree that OPT. 6 would be far better.
Hence the OP should press LINK 6 STORE.
I hope that it works!
Guten Tag Frank
Ich habe das gleiche Problem mit einem LCS 9000. Ich hoffe , Du kannst mir weiterhelfen: Die Frontabdeckungen sind weg , vor mir liegen die 3 Platinen
1: ist die Deckelplatine mit dem Display -arrey drauf, da ist auch die rote Diode eingesteckt und die Infrarot.Dioden eingehackt ist der rechteckige Plastikrahmen. Ein Flachbandkabelanschluss.
2. darunter liegend links ein kleinere Platine mit drei Flachbandkabelanschluss
3.rechts davon eine quadratische (ca. 6x6 cm ) abgeschirmte Platine mit einem Flachbandkabelanschluss.
Welche der beschriebenen Platinen ist die Platine, wo ich den SMD Capacitor finden kann . Sind das die zwei Kleinen unter dem Plastikgehäuse am Platinenrand ?
waren es 22uF / 6V ?
Besten Dank für Deine Hilfestellung

reading helps a lot
More in the linked thread (see above) in english in a few minutes.
Good afternoon RAMABO
You are right , the answer was allready in your post-- sorry about it!
In the mean time I could fix the system after serveral opening and closing! First I replace one of the two 22uF/6V Condensators back in funktion, Get the LCS togeather------ after serveral minutes of working: Plopp ( the know condensator plopp) . the second 22uF 10V went off , disassemble, assemble!
works fine but..... now I turned the volume much higher , zisch , off again!! It is allways blowing up fuse 2+3 400mA /250V T
What do I wrong , why does a higher volume blows the fuse! Loudspeacker are connected to outlet 2 on a BM 9300, mode 2 for the link selected
may be you can help, thanks allready in advance
The two fuses 400mA are only for the +/- 9V supply used. This voltage is used in every amplifier module for filtering and the L.F.Board which sits right near the transformer with the two fuses which is mostly used to control the volume and sound settings.
Normally there's no big load to this dual voltage supply. Most probably one amplifier board is the evil.
So i would replace the two fuses an disconnect both amplifiers (just one plug). Now turning up the volume via the remote sholdn't do any harm to the fuses.
Switch off LCS9000 and reconnect _one_ amplifier module and test again. If nothing goes bad, most probably the until now disconnected amp-Module is faulty. I would sacrifce to more fuses by disconnecting the first amp-module and connecting the second one. Now if you switch on the LCS9000 nothing should happen when you leave it at a low volume for some time. After some time running low you could increase the volume and if the fuses blow up you know atleast that the second amp-module has a defect.
The good thing in this case is that you have two identical modules, one being fine and the other having a fault. This gives you the chance to compare both modules..
