hi Graham,

did you ever document how to re-cord the unit? i foolishly ploughed without research and dislodged the cords. is it just a case of copying the tape door set up and having loads of patience, a pair of tweezers and perhaps a curved needle to thread it round the gold spindle? any tricks of the trade welcomed. I take it i should have been able to dislodge the cd door without popping the cords...d'oh

Unit is a traversty,,, came smashed in the post (mint when i bought it...), tape deck sounds terrible, cd door was catching cd as it closed and cd has no power/or at least won;t spin

we live and learn...i got absolutely shafted :(

I do have a little chuckle when I read the ebay adds promising to safely dispatch BC9300/9500 types in the courier system and do it all for £15 with Parcel Force!!!!

In my experience, most general sellers are rubbish when it comes to packing items for carriage. Not a clue!

I just received a record deck which had the platter sellotaped to the underside. The lid bound up with.........sellotape. The deck was then bound up in one wrap of small bubble wrap and forced across the corners of a carboard box which had been squashed into a trapezoid shape to fit!!

Regarding repair to your existing unit...............

Yes, you should have removed the door without displacing the chords.......too late now!

Regarding replacement, well........yes to all the above, there is no trick but it is not rocket science. Masking tape to hold things in place while you are working, will help.

Remember that the opposite door chords are a mirror image/opposite orientation.

Patience, a bottle of scotch and a cigar will help!

I have replaced both belts and cleaned the tracks on my BC9000. If I switch the BC on, open both lids and press standby, the cassette lid closes first, then the CD's. The difference is small but clearly notable and everytime the same so it's not a random cause of friction. It looks actually very good, is this intentional or just a question of personality with my BC?

Unless the motors are different (doubt it) or the pulleys are of different size (haven't checked), it must be just because the CD door has more to do mechanically which slows it down. Now that I think of it, I believe my BC8000 is like that as well.

It is because the CD lid has the CD clamper mechanism attached.

These times are not exact, but I'm sure the motors run differently in time.

Don't get frustrated, you are close!

Thanks for your reassuring words. I'll try that tomorrow. It's getting a bit late here in Denmark

I am not positive on this, and my BC9300 is in another location, so I can't test.

But, if the motors are timed, try removing the belt (to remove any resistance from the equation) from the CD motor and re-time it.

I *think* that these motors are "clutched" in the sense that if they receive any resistance, they will stop.

This would also give you the opportunity to manually (delicately) try to move the door mechanism without influence from the motor, and note where there may be any resistance.

Don't get frustrated, you are close!

Well I've tried to measure the time the motors run. The plate of the tape deck opens in about 2 secs. The plate of the cd opens halfway in about 1 sec. These times are not exact, but I'm sure the motors run differently in time.

Oh now I understand how it works. So If both motors run for exactly the same time the problem has to be some sort of friction in the tracks?

Yes, likely friction either from grime, or in my case... I also noted one of the guide tabs was a bit askew. Some gentle pressure on the tab to realign it.

Like I said: A very fine line exists getting these just right. It is remarkable how something so trivial can cause these to stop.

Another quick comment...

Be careful with the glass panels while rotating into the service position: Make sure they are not loose! Don't ask me how I know!

If the problem is dirt in the tracks wouldn't the door open if I helped it a little with a finger?

The doors don't have any position sensors, the CPU just commands the motors to run for a specific duration. If the lid moves sluggishly, it may not have enough time to reach the end of the travel before the motor stops. If the tape deck door works correctly, how does the speed compare to that?

Perhaps a VERY judicious use of finger pressure to see how it responds, but again, don't force anything! This is the very reason so many of these units have "popped" strings.

Well, you never know what a problem is until you take a look at it...

Well I bought the BC 9300, maybe I shouldn't because I can't figure out what's wrong with the sliding mechanism. I have removed the center plate so I can see the sliding mechanism. Nothing seems to be wrong, the motor runs when I touch the contact, but stops when the lid is half way open. If I touch the contact again the lid closes ok.

As Mika mentioned... The first thing I would do: I'd clean the tracks that the door tabs ride in. I would also confirm that the tabs are not compromised in any way. I can tell you from experience that there is a VERY fine line between the doors doing what they are doing now and working as intended. Do not force anything.
