GOLD MemberMy friend opened up his V1 today and sent me some pictures from the inside.
Although the mainboard look a lot like the one in Guy’s V1 I not spot a component that could be a battery although the marking C304 suggest a capacitor.
And from a slightly angled view
There are no visible leaks from this component, but that of course does not men that it couldn’t be defect.
Any thoughts

GOLD MemberWhen I first opened mine it was screen downwards on an old cot mattress. I re-inserted the top part of the bracket so it could pivot (unfold) upwards. I then reversed the tv so that the back was downwards and the screen carefully pivoted up.
Thanks. Thats a very helpfull view of TV opened up. I do not spot a battery here either, but could of course (why place it so it is easy to get to) be placed on the other side of the PCB. My best guess would be that it is placed on the large mainboard as the function is probably to keep data when the TV has no power.
Other possible culprits could also be capacitors on the PSU board. Your photo shows two large ones placed in openings in the PSU board.
I can only assume that those sheets would protect from scratches caused by opening the plastic ‘hinge’ beyond its normal range of movement.
Maybe it is more nessecary if the TV is opened up 180 degress. I guess that B&O’s description of it is to be 100% sure that a service technitian do not make scratches when he is working on it.

GOLD MemberWell I found them for 2€ or so in a trift store where they did not know what It was. So if you pay the postage cost I think that will be fine.
Could you drop me a PM with your location, and then I can find out the postage costs

GOLD MemberA little update for usecase 8 where a Beomaster 4500 is used in a link room.
I found out in the Beolink system manual that when the Beomaster 4500 is set to option x.6 powerlink and MCL data is disabled, so only passive speakers can be used.

GOLD MemberI have a set lying here.
I am not sure if there is a difference in size whether it’s for a 26″, 32″ or 40″, and I don’t know which size mine might have come from.
Could you measure the lenght of the recess for the feet on the bottom of the TV

GOLD MemberThe oversight in the design seemed to be though,that you needed to switch the second pair of ‘speakers on/off via the transceiver manually,and could’nt ever have just the remote room ‘speaker operating.
Great with some info from one who had hands on experience with this link system.
When you say:
you needed to switch the second pair of speakers on/off via the tranceiver manually
Does that mean that you have to do that before you can use the remote control?
We used to get around this by reversing the speaker 1/2 connections,as the sockets are cabled in paralel.Speaker 1 (main)then can be switched off via the 2 switch under the cover.
That kind of break the idea of remote controlling in separate rooms. But fortnuatly that got better in the newer link systems 🙂

GOLD Memberso I opened up the TV and searched the PCBs inside
How did you approach the opening of the TV?
The reason for asking is that the disassembly instructions mentions insertion of protection sheets, and I wonder if that is of a specific material or if it could just be a piece of paper or cardboard?
I guess the purpose is to avoid scratches on the painted surfaces

GOLD Memberso I opened up the TV and searched the PCBs inside, and found nothing remotely like a battery!
A pitty. It could be nice to know where this battery is placed, and if it could be DIY replaced.
Worst case if it is like some batteries used on 30 year old computeres, the PCB traces could be destroyed by the battery acid.

GOLD MemberAnyway, on testing, the CD player burst into life and worked faultlessly, for about 20 minutes …. Then the same fault re-appeared and I couldn’t get it to play any CD again! I ran the test mode and am still getting the same ERR 2 focus error.
Pitty that it was not enough. I might have to do some more playning for a longer time to see if my BS Ouverture is stable for a longer period of time. I never got the ERR 2 focus error though.
Note the note about cable and socket matching here: https://www.beoparts-shop.com/product/cdm12-4-laser-module-beocenter-2300-2500-beosound-3000-4000-ouverture-a-o/ Martin
@Martin: The text you are linking to also mentions laser units with F8 <> 2 printed on the cable. If this text should be there would it be in this place (from one of my replaced lasers where the text is different):When I next have time to disassemble I will double check that the ribbon is pushed fully home and will also have a look at the alignment of the contacts.
I might also look into this the next time I look at my Ouverture.

GOLD MemberDoes it show up in the B&O app or in the Beotool app (assumed it is online)?
No unfortnuatly ha has not configured the V1 in the app before this happened
The leaking battery issue is probably more common than one might think. I know that in Denmark any serious dealer will replace the battery before selling a V1. All you can hope for is, that it has not already caused too much damage. I’d let a dealer or a skilled technician have a look, if it was mine.
Do you know if the leaking battery can cause issues like this?
Also, do you have any idea if the battery is placed in the power supply or the Video engine PCB?

GOLD MemberPicture updated with correct wiring for 40+ people ! ?
Very nice. Thank you Matador ?
This thread is still going strong

GOLD MemberYeah it might be a little hard to search for it as it seems do depent a lot about where spaces are set in the search phrase and whether you use . or , for decimals.
I will send you a private message linking to the one I bought.

GOLD MemberI found the diagram for the BM3000 and I can see that the speaker connectors (both speaker 1 and 2) are three pin connector where the third pin for the right speaker carries 5V power and the third pin for the left speaker carries a data signal.
So probably the remote control can operate the BM3000 via the tranceivers IR eye.
The other text I linked to before might just describe the function of the button on the transceiver which the does have a very limited functionality, especially if the BM3000 is not on.

GOLD MemberAccording to the Beotech page linked to earlier in this thread the MCL30 is simply and on/off button ( or mute if you will) for the speakers connected to it
So the operation of volume and channel switching etc. Will have to be done on the BM3000.

GOLD MemberGuess it will be all the same for cleaning products with sticky soft touch coating, e. g. BC 2 table charger / dummy, BeoMedia 1, etc.
Regarding beomedia 1 and Beomaster 5 as well I don’t know if the Bang & Olufsen text will survive this treatment. But might be better than the alternative.
I used a q-tip with silicon spray to relieve the stickyness of the clamper seat.
Good to know there is also other alternatives

GOLD MemberLast week I found another Beogram 2000 for the same price which is in much better cosmetical condition, but where the pickup arm i broken off. I now hope I can combine the best from these 2 decks and get a decent Beogram out of it for almost the same bargain price that you got yours for
I now got around to combining the 2 Beogram 2000’s to one fine unit and the one that may end up as spare parts ( I am waiting for B&O to launch the Beogram 2000c upgrade program 😉 )
First a before picture with the non working, but cosmetically fine on the left, and the working one with the very scratched dustcover and stained aluminum surfaces on the right. The cosmetically fine one do have scratches in the dust cover, but not near the amount on the other unit.
I noticed that the one unit has grey cables while the other one has black ones. The one with the black cables has a higher serial number, so might have been a little design change along the production life.
During the disassembly I leart the on the working unit one of the transport screws was still secured, and while it was wokring I had to do some height adsjustment of the platter after loosening that screw.
The front strip also had scratches on the aluminum on the working unit so had to replace that. It is held in place by three plastic clips that is secured with glue. At first I was not sure If I could get those plastic clips of without breaking them, but with a sharp knife and a little wigeling it was succesfull.
While I was in there I also replaced the belt and the caps. I did not change the speed trimmers as I do not have the equipment for testing the speed for now, so that must be for another time.
On the non working unit i noticed that the motor rattles when I move it arround so it might have other faults that just the broken of pickup arm.
And an after shot of the 2 units
So all in all a succes. It might need some tweaking of the speed and some other adjustments, but for now it is ok. Also the only thing I have with a RIAA amplifier for now is a Beomaster 2400 where the right channel is not working, so no in a hurry with the adjustments.
Whilst the 5000 is essential as a part of the 5000 system as it matches correctly, when taken in isolation I think the Beogram 2000 is the nicest looking – sleek plinth styling and a full clear lid
One thing I have noticed is that the Aluminum line on the sides on the Beogram 2000 lines up nice with a Beosystem 4500 and the aluminum nearly matches the white color on the Beosystem 4500

GOLD Membert is one of the most tempting and beautiful B&O systems imho. The metal surface and the sliding wing mechanism are only two out of a lot of nice features.
Yes it is a very nice system indeed, with some of the B&O magic 🙂
Could you explain, how you plan to approach this, please? Mine is in a very good technical condition, cosmetically the soft touch on both units is starting to get sticky.
I am using Isapropyl alcohol and toilet paper. Had to rub the spot three times to get this result which I think is far better looking than the dusty, scratchy and sticky surface.
It takes some time and rubbing, but I think it is worth it.
You might wan’t to start on the back to see if you like the surface underneath.
If you know how to take of the wings it might be worth doing that to eliminate black spots on them when doing the edges.
P. S.: To my knowledge, the head unit is always capable of playing CDs and DVDs. The socket unit makes the difference, although it seems that not many of the “Audio only” units are available. If the Scart plug is provided (I guess Europe version only), your version is able of playing DVDs.
Yes mine is playing DVD’s, but for the short test I did the controls did not seem that responsible and the interface was horrible looking. Well it’s a long time since I used a DVD player, so might just have gotten to used to streaming movies.
I might Hook it up to my BC6 as a DVD player just because the functionality is there, but guess I’am not gonna use it much for other than testing purposes.

GOLD MemberI was going through the Connections menu of my BV7-55, in the Sound Adjustment section, there are 2 Default Speaker options, Default Video= Speaker3, Default Audio= Speaker2. The manual states these defaults can be changed but is silent on how to change them. I now use the Beo4 remote to change Speakers wondering if I can just change the Default and be done
I am no really sure how this can be done, but maybe someone else can help with this.
Is there a menu option that shows how many hours the TV and DVD have been used?
When the TV is on press Menu + Menu + 0 + 0 + GO
You should now be in the service menu and be able to acces the service counters.
Be carefull not to change any settings in the service menu unless you know what you are doing.

GOLD MemberHello again
I have just installed new belt for the CD tray loader as you can see in this post https://forum.beoworld.org/forums/topic/beocenter-2-cd-tray-belt/#post-30185 and the disc is now playing fine.
Hope this can help fix your BC2 also.
