Hi All
I’m new to the forum and not technical at all so apologies In advance for the questions!
I have a Beosound 9000 MK3 paired with Beolab 8000 MK2 and a Beo4 Remote.
The kit has been in storage for a few years and as we’ve just moved house I thought I’d set it all up again.
Issues are as follows;
1) The system turns on fine, sledge runs ok, buttons on side all function as does the Beo4 remote. The issue is that the control panel isn’t working at all.
2) The sledge runs to the CD but nothing happens it’s not spinning at all then goes back to standby after a little while.
The radio is working fine as are the speakers so that’s something at least.
Questions are as follows;
1) How does the control panel communicate with the system? I can see two flex circuits at either end of panel.
2) I think I need a new laser maybe or need to clean it but don’t know how to do this at all? Should I look to source just a replacement laser or the whole cd deck/laser?
3) Could the control panel issue be linked to the laser issue at all?
Thanks in advance as keen to get working again as it’s beautiful stuff.
Thanks
Dave
Hi and welcome!
Have you tried to clean the two “plastic knobs” next to the disc holders?
I’ll take a look but whereabouts are the plastic knobs located please?
If you mean the two clear plastic knobs one at top corner and one at bottom corner then I have cleaned those but still same.
Yes, it’s them I was thinking of. They make sure no foreign obstacle like a children’s hand is near the spinning disc. If they get dirty/dusty the light beam is interrupted. But it wasn’t the case this time. To bad, as that is the easiest and cheapest problem solver, but it didn’t help you.
Hi,
Let's start with the control panel. Lift it out and check for any lint/dust etc. at the connection ends. Then carefully reseat it so that it is properly inserted. If it still isn't working then try flipping it around the other way and try again.
Are you using the unit in the same physical orientation that is was in when last working? There are orientation springs for the CD suspension that need to be in the correct alignment for the setup.
This is described in the user guide. Also, try cleaning the clear pexiglass pyramids at either end of the top plate.
Hopefully the problems are very minor.
Hi Bill
Firstly thanks for the reply it’s appreciated.
I have cleaned the little plastic bits on the front so it’s not that.
The stereo is on a floor stand so it’s option B for the orientation of the arrows.
Now does that mean pointing up or pointing right?
I’m guessing pointing up which is how I have it currently.
Hi Dave,
For a vertical position, the arrows should point to the right when looking at them from the rear with the holes for the adjusters in the upper right hand corner.

1. Make sure that the control panel is correctly inserted. It needs to be put in towards the middle of the unit, in an 45 degree angle, there are 2 plastic tabs that need to fint into the control panel, then it can be but down. If these plastic tabs are not correctly inserted, the flex cable will not have as good a connection as needed.
2. You could try to clean the laser first. Release the sledge with testmode 72, so it can be moved manually to the middle of the unit, and then it is possible to use a cotton swap with alcohol to clean the laser when looking into the sledge from the right.
Testmode can be entered by pressing SHIFT 9 0 2 5 8 on the remote. Make sure speakers are connected, otherwise it will not accept IR signals. Then press CD on the remote(after the unit has written TESTMODE ON in display), then press 72, and it displays RELEASE SLG. Then open the glass lid, and pull the power to the unit, and move the sledge manually.
If not using testmode, it is possible with the glass off, and the sledge in top position (cd1), to manually turn the big white plastic gear wheel under the left side of the sledge, it is easily seen, and just needs a flat screwdriver to turn a few nudges clockwise, this will release the sledge, and you can now move it manually.
After you have cleaned the laser, manually put the sledge back in position 1, before powering on the unit again.
It the cd does not turn, you need a new laser. And since you have a MK3, it is very hard to find a working laser, you will have better luck contacting some B&O service centers, and see if they will sell you a new complete kit. They are expensive though :(
3. No, but.... if the CD is not working correctly, the units security systems will be confused, and you can have what appears to be a dead control panel, at least for some minutes, before it shuts down by it self.
After shutdown, with CD in pos 1, does the unit power on if you press radio on the control panel ?

Hi
Many thanks for the message and guidance.
I have removed the control panel and refitted it and that is now working.
I will try the cleaning of the laser before contacting B&O so thanks for the instructions.
I have found a new laser cd deck for mk3 for around £250 is that a good price and is that cheaper or more expensive than B&O will charge me?

£250 is a fairly good price. It is probably cheaper than the service center, however, the service center might also do some adjustments to the CD mechanism also. I would check out the price at a service center. It is not straight forward for people not used to working on these units, so if it could save you the time and trouble to pay £100 to get it done by the service center, I would spend that ekstra money and get the warranty on the repair also.
Experienced people can change the cd mech in less than an hour.
Ok I’ll check with them this morning.
Can I ask final stupid questions!
Which button is the SHIFT button on the remote please?
Should arrows on rear point up or right if system is mounted vertically?
It looks like it should be pointing up looking at the diagram.

On a Beo4, you need to add the SHIFT button. Press std.by and list at the same time, then select "ADD", and find SHIFT with the List button, and press OK when it is found.
Yes, the arrows should point up when vertical mounted,
Ok I’ve added shift and got test mode sorted too.
When I enter 72 it says Wrong SRC/TM?
Ok TM72 works I powered off and sledge dropped to the bottom of machine.
How do I then access the laser as the sledge disc bit doesn’t open if that makes sense?

You need to just get the cuetip in under the disc from the right sideYou should see the lasert. You can run testmode 65 which will move the laser all the way to the right, that gets is easier to clean.
So, put the sledge back in position 1, power the unit on, enter testmode, press CD, press 65(laser should move to the right, press 72 to release sledge, and power off and move sledge.
When moving the sledge manually, do it slowly, dont do it with a lot of force.
When you say that the sledge dropped, did it drop by itself, or did you move manually ?
Just a note, it seems that you cannot run any other testmodes after 65, other than 66 that puts the laser back to the beginning.
So you need 72 first, then 65, this should do it.
cij28: Ok I’ve added shift and got test mode sorted too. When I enter 72 it says Wrong SRC/TM?
That is because you should press CD on the remote after "TESTMODE ON"
When in TM72 I powered off and the sledge dropped to the bottom itself

Hmm, ok, maybe gravity helps here. Usually all repair work is done with the unit on table and cd setup for horisontal position.
But does the sledge move back to pos 1 by itself when powering on ? If so, this is not a problem.
You need to select CD first, then 72.
Please double check your manual for the centering spring adjustment. For option B, which references figures 1 and 3, the vertical setups, the arrows point to the right.
Sorry I didn't know you still have the unit mounted in the floor stand. Arrows pointing "up" in that case is correct. Trying to clean the lens with the unit on the stand will be difficult.
You should try to see what error codes are stored - this is Test Mode 27. Write down any errors that are shown. You toggle between sections using GO, and the up down arrows to move among error codes within a section. When you get to the end press GO to clear all the codes.
Now, run though the CD Test Modes 61-68 one at a time and see which one throws an error code.
Here are the CD error codes with descriptions:
CD: CD error.
- 02: Focus error
The CD could not focus within the time limit.
- 03: Radial error
Set when the CD did not get on track after several retries.
- 04: Turntable motor error
Set when the disc did not spin up or down within the time limit.
- 05: PLL lock error
Set when PLL is out of lock during tracking mode.
- 06: Jump error
Set when a seek could not be performed or an error occured during a binary search.
- 07: Subcode error
Set when a subcode could not be read within the time limit.
- 08: TOC read error
Set when the TOC could not be read, no access possible to lead-in.
Ok the 9000 is now with B&O on the workbench.
Control Panel is now working fine - thanks
CD Deck/Laser needs replacing at £400.
An ex B&O engineer offered to do it for £300 but given the small difference didn’t feel it was worth it.
Thanks all for your guidance we got one issue fixed and the other one should be sorted soon enough.
