Hi

I discussed with a german dealer and he told me that every bl5 with old chassis (big power plug) of 10 years old became defective. He told me that b&o has never recognized this defect.

I hope it is not true or just concerning the first ones only. Mine are from 2006 with sync function but still big power plug.

beolab 5, beolab 9, beolab 3, beolab 10, beolab 5000, beolab 8000, beolab 3500, IWS 2000, beovision 7 55 mk2,  beotime, beogram 7000 white mmc2, beosound ouverture, beosound essence, beomaster 900 RG de luxe and the collection continues...

Mine are now eight years old. The main chassis have both been replaced, one in autumn 2011 and one in winter 2012. I read about other cases in this forum with speakers having had more or less the same age and the same behaviour but cannot conclude that it would be a frequent phenomenon – the dealer might do this, however. I was a bit frightened about the perspective that there could be one day no more replacement parts available, so that it would be the end of the whole speaker if the main chassis dies a second time …

It might be of some interest to you that the symptoms of a faulty main chassis were identical for both speakers. The upper (smaller) bass driver didn’t work any longer and as a consequence the speaker refused a re-calibration.

If i compare my pair to yours, i would say that they are older and still working.(2006).

That doesn't mean they won't be defectiv soon.

Thanks for this info about the upper driver and calibration.

Did they replace the old chassis by the new one ?

For each speaker it should cost around 1000 euros all included.

Well, they hopefully never fail!

That does neither mean they will soon be defective Smile.

Some people might not even hear it, but then, the first one made it obvious as it sometimes worked and sometimes didn’t, so one could easily compare …

Yes, so I now have the original danish speakers with the more reliable electrical parts (as written here) but a more recent chassis and probably firmware.

For each speaker it should cost around 1000 euros all included.
That I don’t know for certain, here it was 735,50€ (I negotiated afterwards). You might expect anything between 500 and 1000 Euros and it should be done at your place (or where the BeoLab 5 usually live/play/sleep/work).

Hi,

One of my Beolab 5:s that are 3 years old went down in august last year. I was very suprised that a speaker that is around 3-years old stop working. I was listening to music and suddenly one of the speakers made a loud noise and died.

I had to make a main chassi swap which cost about 2000 euro incl work.

My question: Is the Beolab 5 generally very fragile regarding the main chassi?

I have read about a lot of Beolab 5 owners that has swapped their main chassi both one and two times.

Why does B&O accept this during so many years of production and not fix this fragile electronics?

Best Regards
Martin

It certainly is a worry for Beolab 5 owners, sounds like the fail rate is quite high.

From my personal experience I've owned my pair for one and a half years and they were 6 years old when I purchased them. The only fault I have is one of them forgetting it's calibration twice, they have a 3 year warranty so I'll probably get it repaired.

They are fantastic speakers, although B&O have stopped selling them and with the high fail rates I wonder how long the spares will last so in the future you could have scores of Beolab 5's broken unable to be repaired unless a third party  company specialises in them.

Yes, my Lab 5s were very problematical. Both speakers needed their chassis to be replaced twice during the 12 years I owned them.

Hi,

Thanks for all your comments on this regarding fragile Beolab 5.

Does anyone know WHY the electronic part (chassi) is so fragile? Why has not B&O made it more robust and safe from issues?

My Dealers technician has told me that he changes a lot of main-chassis (20-30 changes) every year in the south of sweden. I dont know how many Lab 5 that are sold in south of Sweden but my thoughts is that this means that almost everyone who owns Beolab 5 will have broken main chassis on one or both speakers in 3-5 years intervall.

This is really a very expensive speaker to own, not just to buy. If you own Lab 5 from year 2010 the mainchassi change will cost about 1900 Euros. The earlier models (before year 2010) will cost about 1000-1200 Euros. Does anyone know WHY there is a difference in the price of chassi-change between older and younger Labs 5?

Best Regards
Martin

I had Nick from Prossers here a couple of days ago to repair my Beolab 5 speaker, he replaced the Eprom as it forgot its calibration a couple of times.

Various Bang & Olufsen stores use Nick as their approved repair specialist as it is under warranty.

Interestingly I had a chat with him regarding the reliability of the Beolab 5 speakers and he said they are "bullet proof". He said he does occasionally replace the chassis but considering the amount of Beolab 5's out there and the large area he works in (from just north of London all the way north to Newcastle) they are reliable speakers.

So that cheered me up, i think we just get to know about the horror stories on the forum.

Hi, that is interesting news.

My repair specialist serves all B&O customers in south of sweden. He says that he does "a lot" of changes of main chassis every year. So when he told me that, then my thoughts was that I should maybe sell my Lab5-speakers before B&O dont make the refurbished main chassis anymore. I wonder how many years ahead they will make replacement-chassis for the lab 5.

But what You say is of course good and positiv information regarding the Lab5.

Hi Paul, I have a problem to find a good technician to help me to fix my not under warranty Beolab 5 in my area in Canada, so I am looking worldwide.

I am an electronic technician and I would like to get your contact about Nick because doing my troubleshooting alone is a tough job.

1) my beolab 5 show constant red light status now not triggering ON (green) through power link from my beosound 9000; no sound dead

a)Before that state I was able to do the calibration and the beolab 5 was triggering on and off by the beosound 9000

b) the beolab 5 was triggering red and green status by the beosound but no sound was coming out!

c)So I replaced my power link cable with MK2 type( because the thinner one was triggering on and off but no sound at all); and surprise

for this very first time . I was able to listen to my speaker for a couple of minute , full blast and it shut itself off; and since that time remain off

unable to change is status!

It look like that the calibration and amplifier work but something else shut it off, kind of protection; why changing the main chassis with all amps and DSP/Crossovers ... and paying a lot if the problem is something cheaper to repair?

Is their a way to find refurbished Main chassis/ parts or troubleshooting guide about this model? B&O seems shy to give troubleshooting procedures or test points to fix their product instead of paying big $$$ to replace all electronics main chassis.

For me ,as a big recycler, changing the big chassis to solve all the problem is a waste of materials and does not fix the real problem and ask big

money expense to the end consumer.

Now my big question ... I need to find an experienced tech to help me to find my problem and fix it or finding a way to get a refurbished chassis at last ressort.

 

Thanks so much

Please could you send me your web repair link for your replacement chassis ?
