Speakerroms not responding

[lenhi]

When I press e.g. radio on my remote, the little square with the redeyes respond, but return to standbymode (two red lights) after three seconds, and the Beomaster 7000 does not react. at all. When I press radio in the main room, all three speakerroms are turned on. I had this problem before, had the capacitors changed in the Beomaster, and then it worked, but now it doesn’t. I know I had a thread about this back in 22, but can’t find it now.

By any chance have you been reconnecting the speaker plugs in the main room recently?

Just asking as it it very important the the speaker 2 plugs that go to the link rooms are connected correctly (left and right).

Thanks!

…and just like that, the syst3m works, though I have done this before, without this result. I think it might have to do with the sequence the plugs are inserted. The Beolab 3500 upstairs is still being obstinate, though; it answers “Radio”, and reacts to volume change on the screen, but makes no sound.

I might have to ask if you do this with the system powered on? Best practice is to power down both the Main room system and the link rooms that has a local power lead to avoid mal functioning.

Sounds like the data connection to the main system is missing. The older MCL compatible BL3500’s will react to source commands and show the source name even though they are not connected at all.

Maybe try to power down the whole system and first turn on the main room system, and then the Beolab 3500

Try to select a source on the main system first and then the Beolab 3500, just to see if at least the sound gets through. If not try the remote sequence Menu + 0 + 4. + GO (on a BEO4 remote). THis will open the sound input. If you have a Beolink 1000 the sequence is Menu + 0 + 4 +Play.

If you have any junction boxes where the cable is spliced check if the cables are firmly connected (do this with the system powered off in both main and link rooms)

Hope this is helpfull

The 3500 is obviously in contact with the black box that is connected to the AUX on the Beomaster 7000. It says Power Link and Audio Aux link on the two din connections, respectively. I noticed this when I corrected the time on the television screen, wghich is apparently not on the same clock as the Beomaster.

This was after I switched the DIN from Power Link to Audio Aux link, and I can now get sound on the 3500 upstairs, switching it on and off with the B1000, but I cannot start the system from there, neither shut it down.

The CX in the kitchen start on radio, phono, CD, tape, and computer (via tape 2), and so do the active speakers in the bedroom, but the Pentas in the main don’t. They light up, but stay silent, until I unplug the MCL Then the Pentas play radio and phono, but the CD and computer make no sound at all, and neither does the tape.

Earlier today I tried to transfer old tape recordings to Adobe audition, but the sound does not seem to feed into the computer, like it has done before.

Maybe I should mention that the CD is a non.B&O.

So grateful for your taking an interest in my problems! I have tried shutting the system down, unplugging everything, and plugging things in in different order. Some years ago, mice had gnawed the wires in the attic, and I had a technician from B&O over to solder that and check the system. They don’t come cheap, I can tell you that. So I really appreciate your input here!

Ok many things going wrong it sound like, but it may be related to one single thing.

To get a better understanding of your system I have made this little sketch. SOme og the things I am unsure of is the role of the television you mention and if the Beolab Pentas are connected to that. or to the Beomaster 7000?

The black box you do mention is called a Beolink converter probably type 1611.

If my assumption of how your system is connected is somewhat correct I will suggest that you try to isolate the problem. I think we should not take the CD player and PC connection into account at first as these problems might be affected by link issues.

Before every step power off all components in the system to avoid anything breaking in the proces:

• Disconnect the the Powerlink wire between the BM7000 and the Beolink Converter. This is only nessecary for certain situation and testing what is wrong can be done without it, so better leave this disconnected. Verify if the problems persist?
• Disconenct the AAL wire between the BM7000 and the Beolink Converter do the Bedroom, Kitchen and Pentas work now?
• If not now disconnect the MCL wire and connect the AAL wire again and see if the BL3500 and the Pentas work now?

This could of course also cause problems if there is a new problem with the wirering, but lets start with isolating the problem

I disconnected both DINs from the converter, then tried with only the Powerlink, and then with only the AAL. Then, I pulled out the MCL. The result is the same: When I click Radio, the sound comes on in the kitchen and in the bedroom. No respons from the 3500, except the display briefly says Radio, then goes back to clock. Twice I could mute the kitchen and bedroom, but now, they just respon with a wink and continue playing.

Should I get a speaker cable instead of the DIN to connect the pentas to each other?

When I went upstairs just now, the 3500 was playing. I used the Beo 1000 to turn it off, then tried to turn it on again. Nothing. Pessed MUTE: the display says MUTED. Pressed the red off-button: display says TV. Now I need a smoke.

BTW: how does the Powerlink know which speaker is which in the main room?

This is getting complicated.

I think you might need to unplug everything from the Beomaster 7000 and then try to connect one thing for example the Pentas to confrim they work as they should. The disconnect the Penta’s and connect the Beolink converter with only the Beolab 3500 connected and so forth just to verify if each part of the system works on it’s own.

Problem is that the data signals for both Powerlink, MCL and the AUX socket on the Beomaster 7000 is connected internally, so a fail on something on one of these sockets can affect the functionality on all the other sockets.

Remember to unplug power to all components before unplugging and replugging things

No not sure that would work. The optimal connection for the Pentas are Powerlink.

There are selection switches on the speakers to choose if it is playing the left or the right channel. The Powerlink cable carries both channels

Correction: When I press RADIO on the 3500, it says RADIO, then TV, and then goes back to clock. This is a new feature.

The thing is, the Pentas go blop when i turn the system on and off, so they apparently get some sort of signal from the system.

Could it have something to do with the OPTIONS>A-OPT in Beo4?

I don’t belive that the kind of errors you are experiencing has to do with the option settings.

My money is more on a defect in one of the components in the system or in a cable.

As advised before I think you need to isolate the problem by trying piece by piece what is working and what is not

One more thing that came to me

Every time after you power down the system and power thing up again start with the Beomaster, the the Beolink Converter and the the Beolab 3500. Sometimes communication between components go wrong when powerede on in other sequence

Location: Denmark

[lenhi]

I agree about the OPTION thing. But I just tried that sequence you suggested, and have now full functionality of the 3500. Thanking you warmly for that, Mads! Also plugged headphones in, and they worked. So, the problem must – as you say – pertain to the components, which leaves me with the option to get rid of the Beomaster, since a repair here i de tabte områder would be impossibly expensive. I should confess that I have not tested the cables yet…

Good to hear that you at least got something to work.

Hopefully it is a matter of cable problems

With a cable to the other Penta, and that one connected to the other one, they suddenly work. Now I am going back to your scetch to see if I can get the sound back in the BV7

Location: Scania, Sweden

[lenhi]

So now I have sound in the main room, in the two other rooms downstairs, but not in the 3500 upstairs. All those three react visually to the remotes,  but do not mute, change volume, or start or turn off the system. Furthermore, the displays on the 4500 in the bedroom do not disclose anything; they just stay dark.

I am beginning to suspect theat there is something wrong with the Masterlink; according to your drawing, the powerlink is not used at all here, so I pulled that out when I needed the second plug in the Penta to connect to the other Penta. Since then, no sound at all from the BV7. And I have nowhere to connect it.

So, problems that persist: No maneuveabilityu from the link rooms;

The TV silence:

No sound from the 3500

För övrigt önskar jag dig en riktigt god helg!

Do the displays also work or is it only sound from them? If no display then It could very well be a fault on the datalink circuit on the Beomaster 7000. There is a transistor and a diode that can fail.

Remember my drawing is just how I imanginge that your setup is/was connected based on what I can read in your post’s to better understand your problem. As I have not seen your connections I can have misinterpeted some information, so the drawing is best guess based on how things usually are connected  Therefor the best would be for you to try to verify if the drawing resemble how your system was connected before the problems arised.

About the BV7 that should be connected via Masterlink so conenction to the Black Beolink converter Box. You might have a junction somewhere on the Masterlink connection where it is split to the BL3500.
