Sony PSX 60

Hi folks,
I have a problem with a Sony PSX 60 I bought from a nice elderly couple. It seems intact, the turnarm looks good, and the speed was holding when he demo'd it.
But the lifter mechanism is not working at all. I opened it up and the bottom was full of cobwebs. The web is full of advice how to fix the damping mechanism, but that seems to be OK. But the post seems frozen in the up position, and I'm worried to try to force it down- it's not making contact with the cam at all.
It seems to have some kind of pivot or something coming off the side of it too.
The platter was also frozen and needed lots of pulling, tapping hard, and then heating with a hairdryer and tapping again.
I think it's been in storage for a lot of years.
Please help! I believe this is a really nice turntable and i don't want to mess it up!
Thanks,

To follow up, I think that other thing is connected to the vertical height adjustment of the tonearm.
Anyway, i tried more lube, heat, tap with hammer.... And it's still stuck.:(

Oh....sorry, I didn't think. And thanks, mech986.
 
I had a PS-X70 that had a frozen cue. I had to disassemble the cue mech to remove the dried grease and relube. Once that was done it was OK. I am assuming it's the same with yours although the 70 has a motorized lever. It's a nice table for sure.

Hi vincei, thanks for your reply. Did you use the vinylengine service manual? It looks very confusing and that kinda worries me...
I have tried everything apart from that, and I've got a feeling that's got to be my next step. Can't you mess up the tonearm alignment or something?
 
I think I just "winged it" and took my time. As I recall I didn't take everything apart, but yes, you can make a mess if you are not careful.
 
I had a similar problem on a PSX 50 but was able to get the mechanism freed up by slowly, gently and patiently applying naphtha to the shaft of the post with a q-tip. Several days of several drops several times a day and it loosened up and now works very well. Just my 2 cents...

Hi, nbarber- Thanks!. I am in the process of taking the while thing apart. I can confirm that many applications of machine oil did nothing. What is naptha?
 
I usually use Ronsonol lighter fluid for that job. Easy to apply a few drops around the shaft.
 
Had the same issues with my PS-X50. Opened the table up. Lubed the springs inside. Removed the dried up old lube as best I could. Dripped oil down the shaft of the tonearm. Still wouldn't come down. I started pushing down on it a little at a time after I noticed that it would come down a bit at a time until it broke through. Only problem is the last time I pushed down too hard and the lifter sank through and now drops too fast so I have to be careful. Was planning on putting silicone down the shaft to act as dampener but I got an X65 so I'm not using it as much anymore.
I put a few drops of oil in VTA post as it was a little hard to move up and down. It became easier to move after that.
As a caveat, while this worked for me it may not for you. Maybe other more knowledgeable members can verify if my method is acceptable in most cases. At any rate, Congratulations on your new table. That family of tables by sony is highly regarded and should give you lots of analog happiness while you own it.
 
I've had a few models in this line, including a 60, and my main table is a 70. One of the tables had your same problem... I think it was a PSX6, if I recall. I had to disassemble much of that area, then clean it and relube it. The Sony tables aren't like some other brands, where adding new oil and gently moving the lever a few times is usually enough to fix it. They often need to be taken apart.
 
Hey nbarber, vincei, Sam Cogley, albowlly, punprankster, janikphoto- I appreciate the replies.
So I have been trying to apply all your good advice. I disassembled the return mechanism and applied many drops of pure paint thinner to the underside of the cueing post. I cleaned and regreased everything that moves, then put it back together and continued regularly dropping paint thinner on top of the shaft, tapping with a hammer etc. Still no luck. I Wil continue......
One question I have is that punprankster, you mention treating the tonearm post and the VTA. Are you saying this needs to be done for the curing mechanism? Is there any physical relationships between the two? Cause my tonearm and VTA all work fine.
Any suggestions what else I cam do for that curing post?

Thanks again☺
 
The way I've handled it is to put a few drops of lighter fluid around the shaft on the top of the table, let it wick in, then push/twist the shaft until it starts to move. Keep applying more solvent until it moves freely.

Hi Sam, this one can't twist cause it has a stabilizing bar coming out the side. I will try to include a picture.
I will keep going with the paint thinner, although I've probably applied it like 20 times... This is a really well built table, so I'm guessing the surfaces are welded together, and I think it was in storage maybe 20 years...

Quick fix, spray wd-40 down the shaft and move it gently until it works. Long term fix, take off the bottom and remove the old grease and re-lube. If it's similar to my PX-50 it should be easy.

Hi Rey1, I'm not sure if it's similar, I think I've gone as deep as I can - had the bottom off and removed all the automatic return stuff etc. In a previous post I showed a photo of the underside of the curing post, which I've repeatedly dropped with WD40 and paint thinner. It is rock solid.
What I haven't done is remove the tonearm- do you think this would help?
 
Hey Rosco,

I apologize, I meant to say tonearm lifter shaft. Like Sam did, I started gently pushing down a little at a time when I noticed that the shaft was trying to sink into the hole some time after putting model train oil down the shaft of the holder. It had to fight through the solidified gunk that the damping fluid has turned into over the years. I don't know if the lifting mechanism of the X50 and the X60 are similar, but check whether there is any slow rebound on the lifter when you push down on it movement on the lifter when you flip the cueing lever.

Anyway, here's the post (Rey1's original) that was quite useful for my attempt to solve that problem:

Good luck!
