Hi,
OK now I can see them!
The arm wants to travel, so the lower pimple (which you show) is ok.
In this diagram:

The lower pimple 239 is trying to move the arm laterally, as your second video shows, but is (most likely) blocked by the upper pimple 66 under the arm.
The guide 68 and bolt 57 need to be adjusted a bit as described on page 14:

Hi,
As I understand, you are still having problems.
To ensure that the arm or bearings are not damaged, do a bearing test. First, disconnect the unit from the mains.
then follow the procedure to check both planes:

Vertical test:
1. Set arm for zero tracking force and zero antiskate force.
2. Balance arm perfectly (perhaps without stylus for safety) .
3. * Place arm between platter and rest post, so it can descent. *
4. Drop a stamp on the head (over cartridge).
Arm must descent all the way for the 1200 series, most of the way for 1000 series with tk 12 headshells and at least lower somewhat for 1009, the lower, the better obviously...
If arm moves without hesitation then vertical bearings are ok.
*Note: for the 1219/1229/1229Q, there is a rubber bridge mounted left of and into the rest post, pivoting on a chrome shaft. This rubber bridge can be shifted/removed to enable a proper vertical test.

Horizontal test:
1. Balance arm as before (no stylus-no stamp...)
2. Apply 0.5 anti-skate on any side of the Anti Skate dial under the tone arm.
3. Bring arm towards center of record.
4. Let arm go.
Arm must return all the way back to rest post without hesitation.
If arm moves without hesitation, then horizontal bearings are ok.
That's it for the test.
Regards,
k
