Getting back to my Ouverture project I have now per Guy’s suggestion in another thread tried to play a CD which use the full 74 minute playtime. I have played it several times, and the Ouverture can play the whole CD without problems.

The problem that I have to press CD twice to get the CD spinning remains however.

I have tried to reflow alle the new capacitors just in case one of them had a bad connection, but that did not make any difference.

The updated part of the servicemanual for the CDM laser available at Beoworld has this passage which might very well be what I am experiencing:

However section 5 is not in the update for the servicemanual, and the procedure described in the older servicemanual is for a PCB with two trimmer potentiometers which is not on the PCB in my Ouverture

So I wonder if a newer version of section 5 in the servicemanual is available?

Also I would have to get hold of the described test CD to do these adjustments

I have also checked the battery to see if there should be any leakage.

It looks fine for now, and I meassure a voltage of 2,93V, so not high priority before the othe issue is solved

Yes it’s strange that it refers you back to a section that is made out of date by the CDM modification.  Looking at the circuit diagram for the new CD interface board (PCB89) I can’t see anything that is adjustable anyway.  Nor is there anything adjustable on the CD Servo and Decoder board – PCB88.

I think your Ouverture and my BC2300 share the same board, like the one for sale here: https://www.ebay.co.uk/itm/375101801373

yes that is the same PCB I have in the Ouverture

In trying to fix this I picked up two defective Ouvertures hoping that another CD servo board might make a difference.

I disassembled my own unit and the one of the defective ones only to discover that they have another type of servo board (and also laser I guess).

Dissapointed I reassebled my own unit, and discovered that now the CD starts playing at first press on CD button both on the front panel and the remote.

So this endedup being a succes, and I got some other spare parts out of it 😀

Now I just hope this will last.

One thing I notice on the defective units is that the have software 1.4 where my original unit have 1.2.

Not sure if it makes sence to upgrade it?

I read in an old thread the option 5 and 6 is available from sw 2.1 which could be interesting,
