Beogram 7000 PLAY problem

[filip_kbh]

I have a Beogram 7000 record player that has developed a strange problem. When I press PLAY, the arm travels to the start of the record, and the 33 RPM light is on and the platter spinning. However, it then stops the platter and turns off the 33 RPM light. You then have to press play again, and it will start playing. Any ideas why? Is it just a worn out belt or is there perhaps an electric problem?

Oxidated microswitch, perhaps.

Amazing. I cleaned S1 and S2 with a fibre brush pen, and now it works as it should again. Thanks, Martin!

I spoke too soon. It fixed the issue when pressing the top PLAY button, however, when pressing the front PLAY button, it sometimes only spins the record and moves the arm to the beginning of the record. It also doesn’t turn on the amplifier if it is in standby mode. I can live with it but would love to fix this issue too.

Hi Filip, it may be worth popping the turntable carefully into service position and closely studying the solder joints from the front panel back to the power supply. Re-solder any dodgy-looking joints if there are any.

Do you have pins 6 and 7 in the phono cable DIN plug? Those can be missing as they screw in and are needed for datalink communications such as turning on your receiver.

Yes, I have all 7 pins.

The switch under the front panel PLAY button was very corroded. I cleaned it but it is falling apart, and I can’t seem to position it correctly for it to work when I press the PLAY front. After fiddling with it for hours, I have decided to accept that it doesn’t work. Can I replace it with another type of tactile switch? It seems to be a rather cheaply made board where a piece of tape was holding the metal plate in place. Any suggestions?

Argh – I am getting tired. Now I only have sound in the right speaker.

It is simply a piece of conductive spring metal that should be able to be cleaned if desoldered. You could switch it with for example the 45-speed one if its damaged. A pushbutton microswitch such as one of these should be able to be retrofitted with minor board modifications, though I have not personally tried it.

It was a DIN wire that had broken off. Does anyone have a diagram for wires? I have sound in right and left channel now but datalink doesn’t work, so I presume I have soldered the datalink wire (yellow) to the wrong pin.

This depends on your version. If it has the RIAA preamp, then it is pin 7. If not and you plug in into the Phono input of your receiver, it is pin 6.

The BG7000 has an RIAA preamp.

Indeed the problem was that I had soldered pin 6 instead of pin 7. Now it works. Time will tell when I revisit that front PLAY button issue. I think the board needs to be positioned very accurately for the pin to hit the conductive spring, so it may just be a matter of misalignment as the board works when I press it with a finger.
