Great that you are sharring your findings here although I think a lot of the members here including myself does not understand the “language” of datalink (or programming code for that matter).

I do however encourage this kind of works as it can sometimes bring great things to the community like the Beotooth 5500 bluetooth streaming device with datalink control that was developed by the user Pilatomic https://forum.beoworld.org/forums/topic/beotooth-5500-a-datalink-bluetooth-receiver/

And speaking of that where many other threads about understanding datalink has been about the datalink 86 protocol, Pilatomic is for sure one member here who has been working with the datalink 80 protocol that you are also looking at, so it might be worth to try and contract him.

One curious question to the above. More of the codes you have listed has been named UNKN. Is that because you see some activity on the datalink bus without issuing a command to the system?

Great hint. I will certanly try that the next time I work on it.

One thing I wonder though is if it makes a difference to adjust the spindle height vs. Adjusting the lifting mechanism

So a note of warning – the sound heard in the video posted above in my case was not related to the spindle motor issue which the comments suggested was the issue.

Ok good to know. Will experiment a lttle more with the brass know before going into motor issues.

For the temperamental issues of the player have you tried cleaning the laser lens – and are the cams on the laser housing all complete and lubricated?

Laser cleaned and all gears in the laser housing is lubricated. Have not checked for small cracks or missing teeths on the gears, so will also do that.

On your player #1 have you noticed if the CD start the counter at 0.00 or if it is a minute or more into the first track?

Good to hear that the brass knob adjustment had some effect.

Even though my CD50 is playing now it still can have time when it spit the disc out at first try. Also on every disc I tried it will start playing 1-2 minuttes into the first track and can sometimes have issues with tracks where it will not play and the counter is just showing the track number. It allways read the TOC though when the disc stays in.

This old thread might be worth reading into https://archivedforum2.beoworld.org/forums/t/628.aspx?PageIndex=1

Seems to be some succes rate with spindle motor cleaning, but it also sounds like a hard job to disassemble it

One thing I note is in one of the later posts the adjustment of the brass nut on the cam wheel is again mentioned for being responsible in how easy a disc will rotate

If you click the image again you should see some arrows to go left/right – click one and it should show you the full size image.
Just working on resolving this. it should just show the large image when clicked.

Oh yes I can see that. Thanks for looking into it

And now after disassembeling and reassembeling things one more time I got it playing again https://youtu.be/1yETrPtyj18

Now I will wait and see for how long it does that. So it might be up to small things. One thing I have noticed is that the brass nut is sometimes moving a little in position. I have now tried to secure it with some super glue at the top to see if that also helps for stability

Yes I saw in the comments to the suggestion that the motor requires cleaning and or lubrication. However the two non-working players that I have both had broken belts, so I am reluctant to believe that 2 players both developed in addition a problem with the motor. Also one player I am repairing for a friend who told me that discs were playing fine before the cd tray stopped ejecting, So unless this two issues are a symptom of one another I am reluctant to start stripping the motor down especially since it appears not not to be a simple job.

Fully understandable. I will also look into other options before trying that. But always a good idea to look into what Others have found in older threads. I will update if I find something relevant.

I should add that with both players it appears to me that the disc is not actually spinning – the motor is moving but it seems it hasn’t quite grabbed the disc so maybe I will try the adjustments of the copper nut first and also tiny adjustment of the teeth of the main cam.

That could be. adjusting the brass nut on my CD50 a little down moved the disc raiser a few millimeters up which seemed to be just what was missing

There is another little update to the inline images. when images are uploaded it should automatically scale to a smaller size and be presented on a grid format.
Once the post is submitted, the images will be clickable to enlarge them.

Please let me know if there are any issues.

I just inserted a picture in this post https://forum.beoworld.org/forums/topic/boegram-cd50-carrige-slow/#post-65828 and even when clicking on it the resolution seems to be very poor even though the image I uploaded is looking fine.

In the video the raiser appears to lift at the end of the movement, that looks correct to me.

At the time I posted the video I belive that it would raise fully up, and the cam wheel would have to move even further. However I found in an old thread that it is only moving fully up when a disc is detected.

However Where I was at this point I had to adjust the cam wheel one tooth and also adjust the brass nut on the cam wheel further down to make the raiser lift the CD high enough to reach the spindle that drives the disc.

The Brass nut had some sort of locking glue on top (the green stuff on the pictue) That indicates where it was placed originally, but it can be hard to see if it should have one revolution more even with a before picture.

Hello again

I am now working on my CD50 and after belt replacement I had some issues with the carrige movement as mentioned in this thread https://forum.beoworld.org/forums/topic/boegram-cd50-carrige-slow/#post-65712

However this is now solved and cam down to adjusting to one misplacement of the camwheel by on tooth, and how much the brass nut on top of the cam wheel was screewd down.

I actually had it playing some tracks on a CD, but after i tried to skip a few tracks it started acting like the one in the video you are linking to.

On thing I will look further into when I have the time is if fine adjustment of the brass nut does any difference.

One thing I notice in the comments to the youtube video is a suggestion about disassembly of the motor and cleaning of it. This might be worth to research further into

Take a look at this thread I made https://forum.beoworld.org/forums/topic/beocenter-6-23-software-upgrade/

you might want to aim for type number 9219-9226 to be sure that the DVI connector can be used with other commands than PC

Also if you need anything tested let me know as I have one of these

Is it this one?  https://shop.oneremote.dk/shop/69068-riaa-amplifier/4199-riaa-ii/

(I assume that it swaps the datalink connection from pin 6 to 7)

No it’s a RIAA from something called Flint Products type 4587.

I found it second hand. Never heard of the brand before, but have been able to find adds for couple of other models with the same brand, but with other connection types.

This one however was ideal because of the 7 pin DIN connectors. Initially I thought I had to make the datalink connections myself, but it seems this was intended for use with B&O with datalink.

Yes that should be possible. I have got hold of a RiAA with 7 Pin Din connectors where the datapins are reversed throug the unit. That makes it very easy to get the conttol part along with RIAA

Thanks for the IPA useage link, I’ll give it a go! I suppose it should work on a BS4 body as well!

It will work there too. I had a BS4 for a short while and tried to clean the sticky stuff of that too. One thing I noticed though is that on the front plate you can rub to a level where it will still have a smooth finish, but if you rub to much you get to a surface that is more plastic like. In any case try a spot that will be less visible to start with.

and the back with the ribs will be a nightmare to clean.

And the belt replacements, yes, you gave me some leads late last year when I did them, I have not rebuilt the unit as yet, but hopefully, later today or tomorrow, I have been busy building a model of a Pilot boat based at Hartlepool, it is radio controlled and is for steering competition use here in France!

Oh yes I remember about the belt. hopefully it will solve the issue.

Also good luck with your boat model. Long time since I have seen a remote controlled boat. I guess drones are a morf popular choice arround here

Just to illustrate the issue I have made a small videoclip which shows where it stops in the end of the video

I have always assumed that the set was on factory default but now I suspect in its past someone has been playing around with the settings in the hidden engineering section menus.

I think I am only the second owner of said tv but am now a very happy ‘bunny’ bearing in mind the cost to me of said unit.

Great outcome of what looked like an irritating situation 😀

I am now inspired to get my BC2 rebuilt and recommissioned.

If you have issues with the CD not playing it can be due the clamper not closing entirely. This can be because of the belt driving the clamper being to loose. I had a thread about it here   https://forum.beoworld.org/forums/topic/beocenter-2-cd-tray-belt/

Also if the black rubber coating on the bottom of the unit is sticky there is some advice to remove it in this thread https://forum.beoworld.org/forums/topic/beocenter-2-issue/#post-55843

The datalink signals are the same for Beograms with or without Riia.

However the pin used in the DIN connector differs.

Without Riaa datalink is on Pin 6

With Riaa datalink is on Pin 7

I think it was made this way to avoid starting a Beogram with Riaa when connected to a Beomaster/Beocenter with built in Riaa

Also For the Beograms with built in Riaa you can connect it to a CD socket (that use pin 7 for datalink) and control it with CD commands.

If neede you can reverse the pins and still control the Beogram

Not sure what could trigger this.

Normal behaviour would be the green light showing shortly at power up and the changing to red (standby).

Does your Beolink Passive have a button on the front next to the LED?

Location: Denmark

[Madskp]

Just to be sure what you mean by always on you might need to clarify in what context it is used as it can be used for the following usecases:

– Link room

– amplifier for passive speakers

– converter for Masterlink (ML) to Master Control Link (MCL)

Next,how you can tell it is allways on? Is the green LED on the box allways  on?
