Hi and welcome to Beoworld!
Great equipment that you have there, and I like the photo of the BS9000 setup, it looks great against the brick.
Firstly I can discount Setup B: The Powerlink socket on the BL1612 converter is an input only, not an output. It is also only used for special setups to provide extra data alongside the Audio Aux link connection.
With regard to Setup A:
- Although I don’t have a Beocenter 7700, I just had a look at the circuit diagram and user manual and I think that the socket that you are referring to as a 7-pin DIN audio out is actually the 4-pin line in-out connector that could be used to add (for example) an external graphic equaliser. It’s mentioned on page 5 of the user manual and called ‘external tone correction’. It should be fitted with a little white bridging connector/plug in order for the Beocenter to output normally.
- A better fixed line-level output from the Beocenter would be the Tape 2 Out (phono/cinch sockets).
- Given that there can be no datalink from the Beocenter, you could simply connect the BC7700 Tape 2 out to the BS9000’s AUX input. Then you can switch off the Remote control function on the BC7700 (switch on the bottom on the left) and operate it manually (only controlling BS9000 with Beo4).
If you are already using the BS9000’s AUX socket for something else, then you need to introduce the BL1612 into the setup. Connect to the BS9000 by masterlink and then connect the BC7000’s Tape 2 Out to the BL1612’s AAL socket. You need to use a lead that connects to pins 3 and 5 of the AAL, as these are the ‘video’ input. Again you will need to switch off the BC7700 remote function. You need to put the BS9000 in A.OPT 2 (see manual) and then you will be able to select the BC7700 as an input by selecting any video source, eg V.MEM.
Note: I have tried to think of a solution that would enable remote control of both devices, but that would require the BS9000 to be set to A.OPT 4 (where it only responds to Beo4 LINK commands). Unfortunately I don’t think this is possible with the BS9000, but other Beoworlders may know otherwise!

^ looks great in black. I have them in Blue, Red and Silver, so far … 😉
What SW version is it? 2.X with the built in clock? CD player working? (one of mine is intermittent – plays fine once it warms up!)

7 pin are audio aux link cables, also called audio link. Power link would have the extra central pin 8 (even if not connected in some version).

I tried to find out some threads regarding the same issue I am having, but the forum 2007-2012 does not work.
I can’t help with the HDD problem, but if you want to search the old 2007-2012 forum, just use google (or another search engine) to search for the following:

I’ve been using a BV10-32 as my main TV for the last three years and am very pleased with it. I also use it with Apple TV and can control it with the Beo4.
My TV has the T2C digital tuner which works well here in UK (albeit a little slow), and has the anti-reflective screen (‘COG’ shown on label under accessories).
The only downside is that the TV takes 30-40 seconds to ‘boot up’, both for TV and ATV.
Mine’s on the rotating motorised floor stand which I find very useful.

Hi and welcome to Beoworld!
I can’t think of a turntable with integrated Bluetooth, but why limit yourself when you could just buy a ‘normal’ turntable (Beogram or other make) and then add an ‘audio bluetooth transmitter’ – lots of the latter available on UK Amazon, although I couldn’t recommend anything specific.
Probably best to get a turntable with built-in RIAA amplifier so that the input to the Bluetooth transmitter is at a suitable line-level.

Two things to add:
- You said you had bought a ‘100 remote control’ – I assumed that you meant BeoLink 1000 remote (or BL1000) so please correct me if the remote is different!
- Do you have a service manual? It would be very useful and is available on this site to Silver/Gold members.

Hi and welcome to Beoworld!
Looking at the remote control problem first, the Beocenter may be in A.OPT 0, where is will not respond to remote signals. To fix this, first power up the BC9500 as you have until the CODE display disappears, then with the Beocenter back in stand-by, use the BL1000 remote to press ‘SOUND’ then ‘1’ then ‘STORE’. Then try the remote again.
With regard to the CODE display problem, this probably means that the microprocessor’s 3V lithium battery needs replacing. The normal technique to get rid of the CODE display is:
- Fix the battery or RAM and then
- Using a Beolink 1000 press: 1271
- After 3 seconds, disconnect the 9500 from the mains and then reconnect. This should solve the problem.
If you wish to replace the battery, here’s a picture of the location (red arrow). You need to be careful desoldering/resoldering lithium batteries – not too much heat and wear eye protection just in case.
And this is the replacement battery that I have used successfully in the past: https://uk.farnell.com/renata/cr2450-nfh-lf/cell-lithium-button-2pin-3v/dp/1319731
The lack of response from the lower panel is probably due to the loose glass panels and the forum has lots of advice about these – I talk about re-glueing the panels on the second page of this thread:

I guess i could try connecting RCA to this connector and use second amp as you advised, but seems like it would be quite a mess of cables.
Maybe just touch the tip of an RCA against one of the visible solder joints on the front (connection point of that two-pin connector), and provide the ground elsewhere. This should be a quick test.
Those laser units need to be taken out from the back part, right? I can’t see any disassembly guides on versions with curved laser path and really don’t want to break any plastic tabs.
Page 7-1 of the Service Manual refers and is for the curved laser version. It is only the very end of the service manual that shows the newer linear CD mechanisms. When the service manual says flex-print I think it means the flexible ribbon connector.
EDIT: I meant to add: the reason that there’s no online guides/videos for repair of the curved laser path models is that they tend not to go wrong!!

That board looks to be the same as mine, and you can see the ribbon connector that I mentioned in your second photo (from CD mech to PCB8).There is indeed a 2 pin connector at the place you marked, it seems to me like it has never previously been taken apart, so it would wonder me if any connections would be to blame. Should i check the voltages on those pins you marked when i get unit connected enough again?
Worth checking both ends of that connector – make sure it is connected at the pre-amp end also, and look for any breaks, or dry solder joints around that area on the PCB.
I would check for an audio signal rather than voltage. I used to use a crystal earpiece (remember those?) whilst providing ground with my finger. You may be able to use a separate amp to see if there is any output, but keep the volume low at first.

I really don’t think that your problem is related to the laser or the 47uF capacitor, because if faulty I think this would prevent your laser from reading the CD at all, whereas yours plays and shows track data; the latter can only come from the laser reading digital data correctly. The CD audio output is also digital data until PCB8 carries out Digital-to-Analogue conversion).
You haven’t included a photo of the front unfortunately so I can’t compare, but this is what my BC2300 looks like (PCB8 exposed on the right):
I would look initially to see if there is an audio output from the board shown above. I have annotated the PCB with a red circle and from looking at the service manual I think this is where the audio output leaves PCB8 – there is probably a small (2-pin?) connector (P65) behind the red circle which take the CD audio to the pre-amp/input selector – probably black wires.
If removing PCB8 to investigate, be careful of the ribbon connector about half way up on the left hand side. This receives the digital data from the CD laser assembly, and should also be checked for security.

I have had a bit of a search but can’t find any info specific to those white cogs. A similar tape deck was also fitted in other B&O systems so you may be able to find something related to (for example) BeoCenter 9300 tape deck. There are a few photos (and videos) online but nothing showing the white cogs exposed.
Not sure if the third photo in this post helps (actually refers to BC8000): https://forum.beoworld.org/forums/topic/beocenter-8000-tape-deck-clicking-issue/#post-55380

I also wanted to amend the channel lists on my BV10-32, but couldn’t make changes using the method in the user manual – it just didn’t work! (I wanted to move the UK Freeview HD channels from 101, 102, 103 etc to replace the SD channels 1, 2, 3 etc)
Although I didn’t try, I think the solution could be to make a Favourite List, but I couldn’t be bothered to move across all the other channels that I view.
It will be interesting to hear the response from B&O.

Since I had basically the same issues on Sony CD player I thought that dirt or dust on the laser could be to blame as well, how deep of disassembly is needed to clean the laser itself and not the lens which is seen from the front side?
I forgot to answer this bit. To be honest deep cleaning of the laser pickup head/mechanism looks quite complex (and I haven’t tried it myself!), so I would leave that for now and investigate some of the simpler solutions first (especially if the CD passes all of the CD Test Mode tests.)

If your BeoCenter 2500 has the curved laser then it is more like the one that is the subject of my later thread here: https://forum.beoworld.org/forums/topic/beocenter-2300-cdm-4-cd-repair/
I have paused work on that at the moment due to family commitments, but actually the CD started working fully after a few days of regular use so I may well leave it for now. Happy to try and assist with your fix though!
These curved tracking CDM-4 CD players seem more reliable than the later linear tracking CDM-12 versions, so these is possibly less information on the forum about fixing the particular problem that you described (i.e CD working but with no sound).
It would definitely be worth trying the CD test modes first so see if that gives a useful indication. Test modes are explained in the service manual at page 7-5 and 7-7. You may find that your CD player passes all the tests, because the fault could be downstream in the audio section.
In my linked thread you can see PCB 8 exposed, which carries out the Servo, disc detector and CD decoder functions on one board (unlike the later models). The circuit diagram is page 2-10 and 2-11. The ‘input’ to PCB8 is a ribbon connector from the back of the CD mechanism, and the audio output can by seen bottom right of the circuit diagram on page 2-11, namely ‘Plug 65 connections 1 and 2’. I would check the physical security of the ribbon cable and of plug 65 first. Also check for an audio signal at plug 65. Note that I am not sure where P68 is on PCB8, but it should be labelled on the board itself.
Good luck, and please come back with any questions as you investigate. Photos may be helpful to explain the problems.

Hi and welcome to Beoworld!
That’s a strange fault, and I suspect that there is nothing wrong with the laser since it is tracking and displaying on the screen. I am not aware of any functions on this model that are only available from the remote, or indeed ‘lockable’.
I would look first at the audio signal connections from the CD Servo PCB to the CD Interface PCB, and also from Interface to Pre-Amp PCB. If the laser unit has been repaired in the past it could simply be a case of a disconnected plug.
Do you have the service manual? This should help you to identify the correct boards and connections to check. Also, is the CD linear tracking (straight path across disc) or the older curved tracking version?

am I right in saying that the BV10 doesn’t have a cinema output, for use with a projector?
That’s correct, but there could be a fancy way of using an hdmi matrix (expander?) to do the projector switching. I have never tried, but it was discussed back in this thread: https://archivedforum.beoworld.org/forums/t/35319.aspx
