SONY PS-LX520 LINEAR TRACKING TURNTABLE TONE ARM BELT REPLACEMENT AND REFURB 

Glad it helped!

Glad you found it useful. I just used mine to digitize 2 albums to MP3, and have many more to go.

Glad I could help!

Did it lower before you replaced the belt? There is a lever that holds the tone arm up. A solenoid coil lowers that lever when energized. If power doesn't get to the coil, it will not lower. The square cover behind the tone arm comes off with 2 small screws. see if you can trace the wires end to end. Make sure a wire didn't get broken when you were replacing the belt, or no wires got disconnected at the front panel buttons. That's the place to start.

I don't know. Maybe this will help, page 14. www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwji6czko93rAhXfgnIEHacaBsUQFjABegQIAhAB&url=https%3A%2F%2Fwww.vintageshifi.com%2Frepertoire-pdf%2Fpdf%2Ftelecharge.php%3Fpdf%3DSony-PS-LX520-Service-Manual.pdf&usg=AOvVaw1hWOUTvGFmJr19Nln9c7Sm That may or may not be the adjusting screw. I don't see how that could have gone out of adjustment.

You're welcome!

Sorry, I don't know why I missed your question. It sounds like something came loose, hard to diagnose without seeing it. here is a link to the service manual, I hope it helps. elektrotanya.com/sony_ps-lx520_turntable.pdf/download.html#dl

It's listed as the same belt for both turntables. If you have the same symptom, 99.99999% chance this is it. My TT runs flawlessly now.

@@DIYBenzGarage Update: IT WORKED. I HAVE NEVER FIXED ANYTHING IN MY LIFE. I COULD NOT BE HAPPIER thank you so much for posting this video I have music in my life again (vinyl-wise).

Awesome!

No, it's a very ordinary turntable. That is going to take some investigative work. It could be a bad control board, or you could have several unrelated issues, bad TT motor, and a tone arm problem. My first thought is something got disconnected inside, second suspect is bad capacitors at this age. Check some of the other repair videos others have done on this unit.

That sony stylus may be hard to find, and you may need to settle for conical. I put my old Ortofon OMP10 onto this TT and it blows me away, but Ortofon no longer makes a P-mount. I also have this cart: www.amazon.com/Audio-Technica-AT85EP-Turntable-Cartridge/dp/B077QG5QSJ/ref=asc_df_B077QG5QSJ/?tag=hyprod-20&linkCode=df0&hvadid=312305907549&hvpos=&hvnetw=g&hvrand=17682145582560915836&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9007356&hvtargid=pla-599646081324&psc=1 Excellent sound, excellent price. I think that would be a big upgrade over the sony.

@@DIYBenzGarage Thanks, I noticed lately that the "SSSS" seem to be more pronounced.. seeing that the cartridge and stylus were the original, I did change out the cartridge and stylus to the Audio Technica AT85EP. It seems to be doing the same thing. Wondering could the tracking be off? I don't see anywhere where that can be adjusted. I had my son listen and he says there is nothing wrong... that he does not hear what I am hearing... LOL. Maybe it is just me...LOL

I have read that a cartridge has a break in period, I don't know how true that is. Give the cart 20-30 hours of play and see if it improves. Could also be the source material, the amp or the speakers (my Klipsch are a little harsh). You may be like me, I'm very sensitive to that "S" sound, often refered to as ""sibilance". Some people don't notice it. And yeah, the whole selling point on P-mount turntables was there is no adjustment, jut plug and play.

I believe the replacement stylus is 4213-d6 assuming it's the original Sony vl-44G factory installed cartridge

On the link above they list the same belt for the 510 & 520

Thanks. I’m gonna buy one today. But in the meantime I’m still playing records by spinning the wheel with my hand manually. I got about a minute of audio before the needle gets stuck. Fun stuff

You will have to watch it and determine when the cause actually happens. Did you lube the rails like I did so it's not dragging?. Check all pulleys and lines for the tracking system. The tracking doesn't actually follow the record, the arm is floating and has a sensor in it. When the arm moves toward the center, it triggers a sensor that turns on the motor to move the whole assembly toward the center. If it's not triggering properly the assembly won't move and the record will skip. If it moves too far it would drag the arm across the record and skip.

The assembly should move in little steps or "nudges". This may help: www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwihuZPbsIX6AhUfkYkEHXjKBIMQFnoECAgQAQ&url=https%3A%2F%2Fwww.vintageshifi.com%2Frepertoire-pdf%2Fpdf%2Ftelecharge.php%3Fpdf%3DSony-PS-LX520-Service-Manual.pdf&usg=AOvVaw1hWOUTvGFmJr19Nln9c7Sm

@@DIYBenzGarage I'll try the lubrication method. I hope it's not the sensor, as that's not something I would know how to fix. thank you for the help!

It sounds like your damping mechanism is stuck in the down position, It may just need to be freed up. The tone arm is "damped". This is typically done with a heavy silicone oil in the damping mechanism. Maybe yours has seeped out, or it's damped in some other way. You will need to take the square cover off behind the tone arm and have a look at what type of mechanism it has. Here is a link to the service manual. www.manualscenter.com/manuals/sony/pslx500-service-manual.html Shouldn't be too hard once you figure out how it's supposed to work.

I trust this site better: elektrotanya.com/sony_ps-lx520_turntable.pdf/download.html

Thanks mate! Silicone oil (AK 500000) did the trick. Have a nice day!

@@Audiophil.Vintage Glad to hear another LX 500 will live on!

Hi MDM, can you help me with another subscriber? Where exactly did you put the damping fluid? Thanks -Tom

Problem like that can be hard to track down. Bad motor (doubtful). Bad sensor somewhere? Bad capacitor? Watch this guys video, there is a mini fuse on the circuit board. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SIYcaBhvj4w.html First look for anything obvious, broken wire, burned component etc.

Does the platter spin or do the lights come on but nothing happens?

I didn't hit start
