Quoted from Yoxxy:
I had this same problem but all switches worked individually. For some reason ball lock 1 worked until balls 2 and 3 went in. A new seitch fixed it. You actually don’t need to replace turntable for removing the switches. Hex head and removing the plastic and you are good.
Further investigation shows that the lock switch mounting bracket screw holes are stripped. I'll fix that and see how it goes.
Turntable disassembly isn't too difficult after all. There really should be a guide for this however. Anyhow I fixed a few loose screws, fixed the switch bracket and the few games I tested show it's now working ok. If it acts up again I will just replace switch 1.
The spinner wobble is actually the decal being a bit crooked making any wobble looking more pronounced. So I consider it a non issue.
I'll wait for my distributor to send me a couple (or one) replacement switch and the proper post sleeve. I assume it's the same fat black plastic that's on the left of the tv?
Oh, and there's a bit of inherent play in the whole assemnly so when the cam rotates the turntable, it does load it up a tiny amount which can change level slightly.
I asked the distributor to hold off on replacing this turntable. Yes, I was a bit frustrated at first, but I also don't want to have Stern replace something which maybe doesn't need to be.
