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. ![]() May 09, 2010 Sometimes an electronic device has been so badly maintained that you wonder if you ought to just send flowers. The linear tracking would stick periodically. Download SONY PS-LX520 TURNTABLE service manual & repair info for electronics experts. 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. Posted on Jan 08, 2011. This is mostly a quote from a post elsewhere. It reflects a concensus from other posts: The movement of the tonearm is controlled by a motor that drives a 3 inch-circumference belt. In your case that belt is likely broke or stiff. Here is a replacement. If you can get the thing open (unplug it first!) you can probably do it yourself. Also clean and lightly grease the bar that the tonearm pulls itself across. This is mostly a quote from a post elsewhere.

Regarding the poor sound quality (and possibly the skipping): check the needle condition, see if exchanging it with a needle (or the entire pickup head) from a working turntable does any good. Check the pickup connection pins (contacts on the pickup head and on the end of the wires coming through the arm from the unit), see if there is any dirt or oxydation and clean the contacts if necessary, also check for any damage to the wires. As for the skipping - a heavily worn needle may affect the sound quality and cause skipping as well - if cahnging the needle (or the pickup head) doesn't make a change, try to realign the weight on the tone arm so that the pickup head will become a bit heavier, this could help somewhat (before you actually try to realign the weight, try to put a small coin or a small weight of some kind on the pickup head while it is playing a record, if the skipping goes away, you need to realign the tone arm weight). This could also be a problem with the tone arm lifting mechanism (may be obstructed by something or damaged so it won't let the tone arm sit properly onto the record and 'grab' the groove). I just mentioned a few things you might want to check, but don't take anything for granted, the problem may as well be elsewhere in the unit. Regards Triarcuate Sep 22, 2009|.
