Question about Sony Ps-lx30 Stereo Turntable System Service Repair Manual

Open Question

I own a sony ps-lx430 turntable. The tone arm sync function is not working properly, how do I fix this?

When i hit "play" the arm does not move to the record, and the turntable stops playing. *If i move the needle to the center of the record, it syncs to the beginng 7" point on the platter instead of the beginning 12" point. *after it has synced to the 7" point, i again move the needle back to the center of the record, *it then stops playing and returns to the tone arm cradle. *at that point, the tone arm syncs as it should normally. *i have to do this each time i turn the player on. is there a way to fix this problem?

I think it's kind of cheap to ask someone to pay $10 for an answer to one question. Sheesh!
I haven't gotten the answer yet, but a local stereo store pointed me in the right direction. Thanks anyway.

SOURCE: won't start

I had the same problem with the arm constantly starting and stopping, and the suggestion above works. Despite, I was a little confused on how to do it. Here's what I did in detail:

- Remove the turntable mat.
- Unhook the belt and remove the turntable platter.
- Once the platter's removed, you should see two plastic white gears in the middle. Rotate the center gear clockwise until its tab hits the larger gear. The center gear should move freely and without resistance until you hit that gear.
- Put the platter back, making sure to re-hook the belt around the spindle.
- Put the mat back.

After that, you should be set!

SOURCE: My Sony PS-LX520 turntable skips with tone arm not moving

Yep - Just did the repair and it was as stated above. Had exactly the same problem you have and changing this tiny drive belt was the fix. I add more details and another source to find this belt:
I had the same problem and a review of forums and my experience with my own fix indicated that this is almost certainly your problem:
The roughly 2.6 inch (circumerence) drive belt (that connects a tiny motor to the worm screw that moves the tone-arm laterally when it gets the signal) likely needs replacement. Mine was intact but old and rigid enough to keep slipping or hang up the tiny motor. Unplug the unit - take out the 8-10 screws to take off the bottom - remove this little belt - scrub the pulleys with tripled-up sewing thread, and replace with new belt. This is a good source:

$6.50 (paypal available) for 2 belts to reach their minimum, free shipping, arrived in 2 days.
You might also want to clean and lightly grease the rail that the tone arm rides on, but this is unlikely to fix the problem without a replacement belt.

First check that you can move the arm right across the turntable platter. Do this without a record to avoid scratching it. If you can take it to the middle at the same height as a record then no mechanical fault is present.
That being OK it perhaps means that too much weight is being applied to the stylus. You can adjust it with the weight at the end of the arm. It should have numbers on, try it on 1 or 2 to start with - playing a record. The idea being to get the pressure just right without making it jump out of the groove or too heavy giving a rumble sound. It's a question of trial and error.

Even if the belt looks fine it's almost certainly the problem. You mentioned "cleaning" - if you got any kind of fluid on the belt it might act as a lubricant and reduce the friction between the belt and the drive wheel, causing the turntable to slow when the tone arm puts a drag on it. The problem may go away when the belt dries out.

My Sony PS-LX520 turntable skips with tone arm not moving


Check the needle, if its not that then you can check the tracking, the relationship between downward weight on the needle and lateral movement across the record. you will need the manual for the instructions
It can be tricky so if you are not sure then consult a good hifi shop or tech.

Hope this helps

Tone arm comes out and touches record, then goes back to cradle


See what kind of arm position sensing elements are used in your turntable (micro switches, optics or possibly other) and check if they work correctly - sometimes a microswitch can be damaged or have oxydized internal contacts or a badly soldered / broken wire and it will not function properly, causing the unit to stop automatically, the same might happen if the sensor is of optical type and there is some dust or broken wires or if the emmiter or sensor is damaged. Also, it could be a problem with the part that activates the switch / optics, it might be displaced or damaged.

If all sensors / switches seem to work well, then check the section which has wires going to those sensors / switches, it's the next probable location of the fault (it might be an electronic controller so there could be damage to some components, broken wires, dirty connectors or bad solder contacts).

It could as well be something else in the mechanisms, wiring or electronics, i just suggested a few things that might cause the malfunction you described.

Hope you can get it fixed.

regards
