      Correct belt?
      Check if the belt rubs on something.

        Does it lift slow?
        If so – dry or wrong lubricants?

        Has it worked while in your possesion?
        If not – wrong cam wheel for this model, perhaps?

          Did you check it with a proper gauge?
          If you don’t know who set up the Beogram and how, you shouldn’t trust the dial.

            Nothing wrong with that pin. It’s free and fine.
            And the typical symptom of a locked pin is that the tonearm doesn’t lift anymore, or only lifts very slowly.

            What cartridge is fitted, and have you checked the tracing force?

              What are all those white wires on the main PCB?

              And where does that module with the SMD caps come from?
              From the trademark logo I assume it must be a genuine Bang & Olufsen board, but I don’t recognize it.

                If the contacts plating has gone, the connector is pretty much worthless.
                Looks like the connector on the tonecontrol module – right?
                Is it “only” the male part that has lost its plating or also the female part on the “piggy-back” PCB?

                  The buttons are stuck in dry lubricants.
                  Pull the knobs off, clean both sides of the metal blade for each knob and the respective
                  mating slot in the knobs plastic backside.
                  Contact cleaner can often help dissolve and shift the dried stuff.
                  Sometimes IPA is better. Try and see.
                  Pipe cleaners are good for cleaning both parts as they can be shaped to suit and will fit nicely in the slot.
                  When clean add a little silicone grease (of the non-hardening type) to the slot in the
                  plastic backsides and push back the knobs.

                  All this can be done from the front.
                  If a knob is really stubborn, you can lever it off careful using a flat-bladed screwdriver
                  from below into the knobs recess and against the front frame with pieces of thin cardboard between to avoid scratching.

                    Maybe there?

                    – Which actually mentions Beogram 4000 as well.

                      Soundsmith in the USA make hi quality B&O replacement stylus https://www.sound-smith.com/bo-cartridges

                      For the SP cartridges discussed here, they only offer a rebuild service.
                      It would be much cheaper to find a good quality stylus on f.e. Ebay and replace it yourself.
                      For the Beogram 1200 it must be a 15deg tip, like SP6/7/10/12/14 – no SP1/2.

                        I have the service manual, but many sections are illegible due to shadows/focus problems from whoever scanned the doc. Pgs 2-5, 4-1,7-2, 10-1, 10-2, and the last page diagram of the CD7000

                        Get the real thing. They are usually neither difficult to find nor expensive, and you can sell it again when repairs are done, if you don’t want to keep it.

                          Yes, those bearings.
                          Not sure if I have a spring.

                            The bearings from Beoparts-shop does not have the extra flange found in some of these motors, but they work fine nonetheless.

                            Looks like what was once a white version. Look for a stamped letter on the serial number label.
                            P=Palisander, T=Teak, E=oak (Eg in danish), H=White (Hvid in danish).

                            Many white Beograms from this time has ended up looking egg-shell or even
                            light beige from decades of age, sunlight and nicotine.

                              A red fingerwheel sticks out at the rear of the operating panel – towards the platter, for fine adjustments.
                              A lit digit is on the panel right above it, indicating its setting. See the user manual.

                              Base adjustments can be accessed through holes the Beograms bottom plate.

                                They also restore the electronics, including introduction of a minor modification to the servo motor control circuit.
                                And they fit a new platter belt. – A quality one.

                                    It’s like that from factory.
                                    It’s timed to run for an adequate time – plus a little – to make sure the drawer closes, even if it should run a little rough.

                                      Did you lubricate using something that evaporates or dries?

                                        Metal film resistors are neither fusible nor flameproof.
                                        They don’t burn themselves – but they get hot and they burst with a flame.

                                        This resistor is a safety component.
                                        If you care about your home and the life and well-being of yourself and the persons living with you, get the real component.
                                        There is a reason flameproof resistors were made and chosen here.

                                        Look what damage a flame-proof resistor did to this product.
                                        Imagine anything else fitted in its place…

                                          Looks like a flame-proof type.
                                          Find the reason it burned and replace with one.

                                            Check the tracking force dial calibration with a gauge.
                                            It could easily be way off.
