HI again. i have followed the disk tray aligning processes as detailed in my previous post above following the service manual instructions AND it sort of behaved for a day, played superbly and sounded Great! Please see my pictures for the relevant places that were realigned and indeed some were well out of wack. The tray height adjust was the most fiddly ironically because you have to ensure the disk clamp magnet does not foul on the metal sheet glued to the back of the cd tray, quite WHY they put this there AND left not really enough clearance around the magnetic disk puck perplexes me rather a lot. Can anyone verify that my closeup of the clamping system is complete? There is nothing missing from the lower 'drive' spindle, i would have expected to see some kind of rubber ring pad or something for the cd surface to 'bite' into to prevent its spinning or sliding about whilst spinning up? next day i powered on the main system and wammo, back to square one with the disk spinning up (WAY too fast in my opinion) then because of the speed, the magnetic clamp fails and then the disk and clamp run free making an awful noise. Then the tray mechanism starts to play up, throwing the drawer out so forcefully the cd flew off the tray! then half going in, or not at all, or slowly ponderously closing the drawer, or refusing to open or respond at all. So i think we have something of a reproducible problems here.

1. the speed regulation / reading of cd TOC seems to lose control intermittently, once it does it can be days before the deck works properly again, something to do with capacitors do you think?
2. The tray loader mechanism loses control intermittently and again, remains until maybe a few days later of inactivity.

SO there is something wrong with something on the circuit board? Does anyone know of reputable UK based B&O vintage service centres i can ask about this? To an expert engineer it might be quite obvious whats gone wrong wit my cd deck. thanks in advance Jon  

Hi Martin, would you mind casting your eyes over my recent updates on this cd tray/ playback problem please? I have tried out a fair few things from info i have gleaned. It seems as per my last update after a few 'tray' adjustments via the service manual, breaking it down,

1. i have found the cd motor spinning up way too fast, breaking the magnetic cd clamping thus the cd and magnetic puck run free inside the housing. When this does not happen, generally the cd player works for a day or two, then repeats the issues.
2. The tray has intermittent open close problems, sometimes working then other times having various fits.

Most of these issues seem to all show up together, when one happens, so does the other. if as you say i need parts replacing and soder joints checking, is there a service centre that would undertake this work relatively cheaply? This is a second hand cd deck and despite me being mostly annoyed with it alot, it sounds great when it does work. Also i now have a 5500 receiver that needs its phono input rca sockets resoldering, so a place that can take these on, does it exist? regards Jon
