marexy: Torx 8 is correct one.
Torx 8 is correct one.
Torx 10 to be more precise. Torx 8 can damage the inside of a T10 screw when more force is used.
But for this occasional job T8 will do.
marexy: You can repair broken spakers with 5€ costs if you are handy man :) Maybe some one will be angry for let go of these information...but sorry ...why pay 250€ if you can DIY. Yes our local service want 250€ for job...OMG..why .. it's 1 hour time job if you DIY.

Stop putting the dealer into a dark light.
The dealer won't charge you € 250,- for just cleaning.
Often these speakers are brought in when they already have weird symptoms or already are not working.
On a rare occasion customers bring in the BL4000 before the malfunctioning.
As your pictures show you can see that the foam lies accros the PCB layer. More than one culprit probably could have caused a broken BL4000, or are about to break. the places of foam changes wheter it is a left or a right version.
As you've mentioned that you fixed several, you should or could have known that. One might be lucky.
Most often a broken BL4000 isn't fixed by just cleaning. (And I've done a 100+ of these, believe me). And SMD soldering skills are beyond most of the majority here. Let aside the equipment you need for proper soldering.
One can attemp to remove and see what happens, but isn't a quarantee for succes, as you say.

marexy: I did not replace foam with original. You can buy foam like original maybe some other colour and cut it. works ..with no problem. I did some sound test and it is no difference in sound !! So no need to buy original if it is more than 10€ per speaker.

The foam is partial used for acoustic purposes, but also for preventing damage to the wiring and unwanted possible vibrating noise of it against the housing/PCB/etc. These drivers do not have a casing of its own. So the entire interior is endured to what the drivers deliver.
If foam wasn't neccesary, B&O wouldn't have used it. If not, then the question might now be why the wires are perished (probably caused by the sharp soldered parts)
I agree with you !
Beobuddy
Sorry I do not put all dealers in bad light.
Just one service!
So how much is replacement foam new ?
And with the rest i agree with you :)
My purpose is only to help people who are very eager to own B&O units and do not have a lot of finances for repair costs of original servis centre.
That's all.
All those who have B&O i'm sure that they will buy much more in time :)
So ..it's good for you and for the rest of us :)
like Lampizartor in best times ..before he start to count big...

You have broken spekars- faulty or you just want to replace foam ?
marexy:You have broken spekars- faulty or you just want to replace foam ?
All I can say is, that it seems a very high price for checking and (maybe) replacing the foam.
I am sure, that if the damage was done, you'd need a new module (the old stuff is veeery sticky),
which for sure will come at a much higher price.
As for the (different) practices of the dealers in DK - there are only 3 (or 4) repair centers in Denmark.
All repairs are send to those per region, period!
Either the guy in CPH did not care, or he knew, that - with damage done - you probably would not want to pay the price.
As long as they are ok, use your DIY skills according to the instructions in this thread.....
....and don't hesitate for too long.
MM
There is a tv - and there is a BV
Be carefull..
You need to do step by step and clean ALL stains from foam left overs.
Agree that 470€ is the price of good used one in Ebay with serial 18 and up..
So ..wish you a nice service trip :)

NO...95% you never need new PCB...just 100% cleaning and checking critical areas!...if speakers work :)
It is best to solder all joints under foam just to be 100% that stay in good working order.
h1npw: Wow! That's amazingly! Isn't the internet great!? So we know it's somewhere between 142... And 143335. Marexy - can you give us a 5 digit start to your serial number? Any more volunteers to do a "Michael" and have a look so we can narrow the gap even more? Cheers Nigel

I purposedly wrote wrote: if the damage is done.
Cleaning a multi-layered PCB module is not an easy job.
Maybe you can do it?
I would not advice anybody without 'professional' skills and gear to start that adventure.

You have made good points - and some people will always be gratefull, but never all.

When an official B&O representative in their main flagship store speaks the way he describes I seriously think they have a customer relationship issue. But, even more, I think it is a bit scary knowing that there is plenty of old Beolab 4000 and 8000 out there, maybe risking electrical issues or maybe even fire? Since the goo might trigger bad things on the electrical boards I don't think safety can be assured at all times.

That is a good point - however, I am not sure how dangereous this is.
Never heard of it.
The speakers simply stop to work, when 'the damage is done'.

Same here but you never know. There was a fire in a B&O shop quite recently, I think it was posted here on the forum too. Old electronics are more prone to critical failure than newer but maybe the risk of fire is low.
It is very unlikely that they had old BeoLab 4000/8000 connected there ;-)

Michael: All the retailers I've been visiting in Sweden have an area with used equipment and also sometimes they have their own speakers in the office or so.

Certainly the danish stores have too.
But most often these are not connected, just for display.
Anyway, I'd say, that a BL4000 would stop playing, long before it starts burning - and I have never heard of a 'burning BL4000'!

Did you buy theses new - or did they come from a re-re-reseller?

StKong: Millemissen: Did you buy theses new - or did they come from a re-re-reseller? MM There is a tv - and there is a BV. Hi Millemissen! I bought them recently, and at a fair price since I suspected the presence of black foam. They have spent their entire life in the same home, and I am the second owner. Luckily one pair is alright. (I have a third pair at a different location that I received as a gift. Will have to check those soon.) But henceforth it's easy for anybody looking for Beolab 4000s: Since mine are both from 1997, as a rule of thumb buy 1998 and later!

Isnt 14xxxxx year 2000? I have a pair of BL4000 14 with white foam and I think they are amongst the absolute first with the white foam so the shift was probably done sometime spring 2000.

Have a look at the serial labels pictured further down in the thread. Both have Roman numerals MCMXCVII which is 1997. The change was made early on.

No, no that is the year the product was introduced. Beolab 4000 came out 1997, so thats what it means. For example, my BeoSound Ouverture, also from serial year 14xxxxx says MCMXCI which means 1991, Well, the Ouverture started production 1994, but it is a successor to the Beosound 2500 with the same design, so thats why its there. Its a tribute to the start up year. Not the year of the production date (if its not much lower than 14xxxx.
Checked one of my pairs, serial number 141XXXXX white foam.
StKong: h1npw: StKong - Can you confirm one pair of yours is black and one white? Cheers Nigel Certainly, Nigel! I had a busy day yesterday, but here are the pictures and they confirm what we expected: 14069xxx - black foam 14555xxx -white foam Here are a few pictures. The white foam feels and looks like new. The black foam looks alright, but feels spongy when touched lightly.

Already posted this, but saw following post also....
I have a pair that are 141XXXX and white foam.
Mmmmm that's thrown a small spanner in the works....
Marexy has a 142.... that's black, and Razlaw has a 141.... that's white!
Maybe they had 2 different assembly lines going when they changed, but given the volume of production must have been relatively small, I'd be surprised if that was the case.
Anyway, I think we've been very successful in narrowing the point at which the change was made and we should all give ourselves a big pat on the back and have a beer!
Many thanks to all who contributed and I'm sorry there was a bit of angst on the way - I'm sure misunderstandings were due to language translations...It's such a shame when it happens

Very interesting, this thread. I just opened mine - serial nr. 14608xxx. White foam 😊
(edit) I just saw in an earlier post that it was narrowed down to between 142 to 1433xxx. Well you got a nice picture of my 4000's anyway... 😉
