Hello,

Strange question here, but when I press play on bg it sometimes drops off

This all depends on the vinyl, some it plays and catches the grove others It dosent.

Is there a slight size diffrence in all vinyl.

All adjustments have been done..... So kinda beat on this oneAngry

There is a standard for the position of the lead-in groove. If your Beogram has been correctly adjusted and set up, the problem
is with the record - and yes, that happens. Not all records live up to the standard.

You've only just adjusted the set down on this BG haven't you? It's possible that it is just at the limit of catching the first groove. The vinyl could be slightly smaller - try comparing them. Maybe another slight inwards movement of the set down point is needed?

The  turntable is probably catching on the flat grey cable. Press it down a little.

I have seen this on numerous occasions after I have rebuilt a deck.

Hi,

It's the white section of the gear that is moving/ sticking. It plays but when you move the arm that it's sticks and then it won't return/ stop ..... Worrying and driving me mad!![:\'(]

I remember a few years ago I stripped down and rebuilt a 2200 and the timing system was built on cogs/belts. All I remember is that you had to have the parts in exactly the right position with respect to the other bits or it would be out of sync so I vowed never to do it again.

As with a lot of these things, take pictures before you touch it so you know exactly how to put it back the way you found it. But I think we curently have a summary of

  1. Gearing issue
  2. Setup/Adjustment height needs looking at
  3. The grey/white cable is getting in the way.

I'm not sure but is it possible to test replacin the platter with a cardboard disc with some holes cut in it? That way you could have the record raised to the normal height to test if that cable is clipping/brishing against the turntable when it's spinning.

Also make sure you're really careful with the stylus or maybe remove it if you're working on it. A Friend of mine managed to damage a working MMC4 a while back and I think the swearing was heard about a mile away!

I have gave up, it is now away to be (hopefully ) fixed at the repair shop.

I am lucky enough to have a repair centre near with a couple of ex b&o repair staff. Fingers x nothing to drastic [:\'(]

My copy of the endless river by Pink Floyd is smaller than the rest of my record collection and the arm on my BG6002 misses the record and slips off. All other albums are fine. Some of the new Beatles Re-masters wont fit onto the centre spindle on that particular deck either. Strange!

You can make the deck work with no platter on so you can see/hear what is happening.

First remove the cartridge for safe keeping.

With the platter and black plastic disc removed press play while holding the black centre of the turntable down as if it had an album on it.

Allow the turntable to spin under your finger until the moving carriage comes to the play position, now allow the black centre to rise.

The turntable will continue to "play" and you can see/hear what is happening to the "inards" of the deck.

My money is still on that ribbon cable touching the arms of the turntable as it revolves.

It's the mech that lowers the arm that was making (clicking) noise, from what I could make out. But will post the outcome.......... Hopefully a happy oneUnsure

I compare owning a beogram to owning a race horse

1. Beautiful to look at

2. Designed for purpose

3. Has to be well maintained

4. And can cost you a fortune, when it all goes wrongSurprise
