  • Re: Credible alternatives...

    I only have B&O, haven't been able to move to another brand. I am still buying 2nd B&O bargains for which I have no use for. Just bought a Beosound 3000 and Beolab 6000 speakers for R5000.00 which is about 312 pounds.....Where it will go....who knows. I just don't get that special feeling from other AV brands nor do they get the wow from visitors. My BV11 is still a head turner.

  • Re: Time to upgrade?

    I voted a mixture of new and old. If the technology for TV's only changed every 10 years then I think people would be very happy buying a B&O TV. I am not interested in buying a new TV every 2 years so a B&O TV for me is fine. Still find my Beovision 11 really beautiful and have yet to see something like that out there. Really isn't B&O's fault that the technology changes so rapidly and that consumers are buying into it.....eventually it will probably come to a halt and hopefully

    [quote user="solderon29"] Thanks for sharing info,that costing makes the repair "do-able",although I imagine when you factor in labour costs,it could be at least double that if the work were done by a B&O service agent ? Check the tweeter before fitting and powering up the new modules? Regards, Nick [/quote] Thanks Nick, my friend who was helping me with the repair said he checked but I will make sure we check the tweeter again. I expected the cost for two modules to be a

    Just for everyone's information, the cost of the power board and amp board is around 133 pounds. That's not bad. I am ordering one of each.

    [quote user="marexy"] these digital amps....no go... BL4000 clasic trafo amplifiers MK1 are4ever :) Sorry ..i have same problems with BL4. [/quote] So clearly its better to have the MK1 speakers! Such a pity as they are impressive the MK2. I have asked for a quote for new boards from B&O but I suspect the price will be astronomical....otherwise I must look out for one lonely BL4000 speaker. Thanks everyone for the help though. .Ben

    Hi Polarity of the cap is correct, I double checked again. (Any check is worth mentioning) We did some more checking and now understand the circuitry a bit more and this is what we have found: 1. The -12V line switches on correctly when a signal is applied to the speaker. 2. The +12V line is on all the time, regardless if a signal is applied or not. We have checked on the other working Beolab and this line should be off when no signal is applied. 3. With no amp board connected that status LED switches

    Hi Martin We've checked the boards, cleaned them, no corrosion from the foam at all. Any other ideas or tips? Thanks Ben

    Hi Martin i was hoping you'd read my thread :) I have attached a photo of the amp board where the cap blows on the -12V input line. its the one with the arrow pointing to it. These are the original caps that were fitted to the speaker. We then changed those 2 caps as the originals were swollen. On powering up again we had only the one cap blow. As previously said we found that there is no -12V output from the power supply board. The +12V line and the +12V standby line are fine. -12V pin 4 and

    Hi Soren Thank you for replying. We checked the standby and it measures 12V so surely it can't be the transformer? The speaker powers up but after a few seconds the cap blows. It just seems impossible without a circuit diagram to be able to trace which part could be faulty. I have the service manual but they just recommend to change a module when there is an issue. Is changing the module the only option?

  • Beolab 4000 power fault

    Hi One of my Beolab 4000 MK2 speakers has developed a problem. it keeps blowing a cap on the amp board. With the help of a friend we managed to trace the issue to the power supply board. There is no -12V output on pins 4 and 5. it seems impossible to trace which component is at fault. Anyone have any ideas or does someone have a board to sell me? Thanks Ben
