Turntable autoplay: tonearm not moving into position

[madmox]

I have an Onkyo 1260f. Auto play isn't working (play light flashing). Pulled off the bottom cover and cleaned things up .
The tonearm gear lube had turned to honey, so, I scrubbed it out with isopropyl alcohol and lubricated with white lithium grease. Put it back together and tested it out.
When I hit play, the tonearm slaps toward to the right, like its finishing a return cycle and doesn't move into start position, (play light flashing). If I give it a little nudge, it will move into proper start position. It seems like its having trouble, “getting over the hump”, of the tonearm slide bar. When it tries to move out to start position, it bumps up against it and moves back to the return position.
The drive motor seems to be working fine and all the gears are in great shape. I tried the reset procedure, where you run the play cycle with the arm locked down, no joy. I'm scratching my head here. Are there adjustments somewhere that I can fiddle with?
There is almost no information for this model on the net and the service manual is, mainly, schematics and parts lists, etc.
Thanks for any help

Usually one of the first areas that causes issues is the cuing mechanism on vintage TT. I would look in that area maybe old grease there too or a lack of cuing silicone if its that type.Hope this helps.
