Beosound 9000 mk2 with sledge issues video included

19 replies

Hi all, thanks again for this forums help. Its been a great guide in getting most of my B&O gear up and running again. And thanks also to some special forum members out there that have helped with advice and even spare parts.

But alas, my Beosound 9000 mk2 is still having issues.

Here's what I've done so far, I've replaced the rocker arm with a new one, cleaned the "speed wheel" and tried adjusting the cd sledge height. I've checked the alignment slots and its been set for horizontal operation without a stand. But I'm still having issues with the sledge not moving from CD 1.

I've created a little video showing the problem.

Matador43 you're a genius!

I just put the glass back on and the cd sledge works beautifully. But now i'm back to my original problem of the cd scraping on something when it spins. It takes awhile to spin the cd and when it does it spins backwards. When it stops it displays "pause"

Dirty lens? I'm not sure as it was cleaned when it was apart. 

For the CD scratching when spinning I dont know: the two eight adjustment possible (clamper and sledge) are as far as i know unrelated to spinning height.

The second symptom (play,spin,pause) is usually an aging laser. If you have changed it already, i dont know. If not its the first to look for.
Did you perform hmm the test modes ?

Try to locate what causes the noise. Does it come from the cd itself, which scrapes along the holders, where the cd is held when placed, or is it the APS disc. By lifting or pushing the illuminated cd-cover you can check whether the APS disc scrapes or not.

Quite a challenge to achieve "Less is More" while having the Beovirus.

Hi Beobuddy, I think the scraping is coming from the cd clamp above the cd, if I lift the clear illuminated  plastic up just 1 or 2 mm the scraping sound goes away. I think this is what you call the APS disc. Mayb I should adjust this with the 2 small screws under the silver / grey plastic cover?  What is the ideal gap between the glass lid and this clear illuminated plastic? as I only have 1mm now. Can the glass be adjusted so it sits higher? as it looks like my glass is not completely horizontal.

 

Thanks again guys for helping me out.

Yes the glass door can be adjusted. If you have any service manual it's inside.

If not, adjustment screws are located in the "control box" just above the hinges: two very littles holes.
Right is under control panel, Left, you have to remove the top plate. you need a little Allen key (2 or 3 mm, can't remember).

In mine I had to set the glass and the clamper so everything is sort of parallel. Hope this helps.

Thats great news. As I now have adjusted the APS (the clear plastic cover thing) so its not scraping the cds, but its soooooooooo close to the glass now. And I still have the cd spinning backwards and the pause error. So I guess maybe a new cd laser lens?

Mine is like 4mm from all plate to glass.

Most likely. Cheap to find, easy to change! Your sledge will soon be running between tracks!

The top of the sledge should be paralell with the aluplate. If you need to adjust it waay up, something is wrong.

1. Did you remember to press the black plastic part for the clamper arm, correct back into its place ? If this is not correct, this will cause the APS part to sit to low.

2. I have seen a unit where the APS part was warped/bend. I took it out and heated it up with a hairdryer, and carefully bend it back again. That removed the scraping from that unit.

3. Are the laser assembly correct installed in the holder ? if this is not correct, it will also cause the disc to sit to high, and hit the APS disk holder thingy,

Something is not correct assembled in your unit, that is my guess.

Regarding the pause of cd. It needs a new laser.

And for further testing in the future, if you remove the glass, then open the glassdoor before selecting cd as Source. When the glass is removed, the sledge will not operate unless the lidt is "opened", Once the unit thinks the glass is opened, the sledge are allowed to move, but only slow.

Be carefull to always select cd position 1 before setting the unit into std.by without lid, since this causes the lid to close, and the sledge cannot return since the glass is not there.
