Beolab 5. When you need help with your ICE module
36 replies
It takes a serious amount of time (and money) to create steady and reliable environment to test and repair modules and BL5's. To fix a ICE module with just a multimeter will help you, but for more reliable results you need to test them for a longer period of time.
And even despite all the equipment I have, I don't have all the (software)tools that B&O has when it comes re-program DSP boards.

Hi @beobuddy,
Speaker type is 6881 with SW 2.6 (not sure which revision of speakers this is mk1, mk2 or mk3).
Yes, speaker stop responding to remote controller commands once it gets warm (after 1..3 hours of normal operation - no loud audio there).
I can certainly check if micro is covered with something but how do you draw any conclusions out of it?
How would you go about fixing something like that? Do you offer service to fix it?
Thanks,
Henryk

And for testing ICE's and chassis for a longer period and more heavy load, I have a dedicated BL5.
At the picture you can see the custom made extension cable between the chassis and the loudspeaker itself with the same connectors used by B&O to achieve that reliable connection.
All, again, to get the most reliable test environment and result.

Hi beobuddy,
I started just now a again. pressing the top for a few seconds, the LED starts blinking green, the micro comes out…. but nothiing happend. after a short time, no sound and the micro drives back, LED is blinking red.
As I remember, when I got the seaker, the procedure starts like now, but there are different soundings to hear, the micro comes more out after the test - test done. What I did‘nt understand, both speakers running in the same way
Thanks for any idea
p.s. I just got an offer for a set og MK3, SW 3.0, serial 2153…. for €6750, model 6881, but from a private person sayinmg the are from 2012. What do you think about?

With my Beolab 5's one of the two 1000W amplifiers failed in each speaker after about 15 years. My dealer sent the compelete electronic modules to B&O Denmark where they became renewed, costing 1200 - 1300 Swiss Francs each. Work fine again.
One of my Beolab 5 has gone faulty. What happens is that when switched on, it emits a tone (sort of mid-range) then cuts off and the light turns to a flashing red.
I’ve left it off for an hour or so, but still has the same ‘feature’
what could be the diagnosis - worst case, I’ll have to have the chassis replaced - in which case I’d do the pair just in case.

Hello Beobuddy,
I hope your search for the source of the BL5 issues is successful as I think it is critical to the longer term preservation of these beautiful speakers.
You mentioned this coating on part of the DSP board. I noticed that Kose Trading has a picture of a board that doesn't have this coating. It's not perfect but might be just enough.
I see a H8S/2240 microcontroller IC, the other is harder to make out, but I think its an SST 39SF040 which is a CMOS Multi-Purpose Flash chip. My bet is this is where the ABC calibration results are computed and then live, (maybe also the pin code?). This may be at the heart of that failure.
It does seem like there are at least two revisions of this board I've seen B6143219 and B6143575

Hi Beobuddy
I live in Malta and have a faulty Beolab5 - I've had them since 2007. The local B&O agent says the ICE is faulty - they can't source a replacement. So I need to source it myself and supply to them for fitting. What are the sources? Do you supply them? I see Kose Trading have them for EUR700 on swap basis.
Has anyone advice on the best way to handle this?
