Help! Sony PS-X600 - Platter won't spin!

I've been wanting to try out a Sony PS-X600 for years after reading the rave reviews here on AK and elsewhere and after owning a PS-X55. Today, I got the chance to get one. Only the platter won't spin! The tone arm servos seem to be fine, but it is as though the motor is seized. I haven't spent anything on it yet.

I was able to put some sewing machine oil into the gap by the spindle, and with the platter on, it seems to rotate reasonably well manually, but it won't move with the power on and the start button depressed. The tonearm does move into starting position, but no platter movement.

I'm hoping that with your help, we can resurrect this beautiful table.

I hope I'm not biting off more than I can chew, but this table has been on my want list for quite a while, and I'm willing to get deep and dirty to accomplish that.

I was wondering if there was a braking mechanism that was locked tight. It is very stiff. Better since I put some sewing machine oil in it though. So I'm not quite ready to check for power to it yet.
 
I had a PS-X600 that did the same thing- mid track. Turned out to be dried out grease in the spindle. I had only days earlier received a TRASHED E-bay PS-X520 that I was able to sacrifice to figure out how to get at it. Bottom line is the motor needs to be disassembled and cleaned, then re-lubed.
 
i just looked through the manual and it looks a very complex thing ..
record size struck me too .. but not understanding how this thing ticks i will have to be a watcher and learner ...
 
Update! I'm thinking you may be right about record size. I'm going to watch a few YouTube videos to see it in action. It actually did move a slight amount on start but stopped right away, and I don't see any light.
 
I've been wanting to download the manual, but it is game night. Grandson is here and Trivial Pursuit junior is on the menu. I will probably have to wait until Sunday to really dig into it.
 
it is a very busy manual .. it needs breaking down to what works versus what doesn't ...
obvious simple things first ..sensors switches and tight things that should move easy ...
 
I have a PS LX5 which is not as good a table. It does have a brake adjustment on the platter that stops the rotation at the end of cycle. That should release as soon as you push the start button. My unit would not cycle due to thick grease on the arm actuation cam. I also think your disc sensor circuit is having problems.
 
I opened her up today, and she looks pretty good inside. I did find the motor a little hard to move, but unless the unit senses current draw, I wouldn't expect the motor to be the issue. I can't find anyplace to add lubrication without taking the motor apart, and frankly, I'm afraid to do that. I don't know how it comes apart, and experience tells me that is a recipe for disaster. The owners guide states that the motor has been lubed for the lifetime of the deck, whatever that is.

Here are some internal pictures for those interested.

Wow that is a lot nicer build than the PS LX5 there are no similarities between the two units. Sorry, I wonder what the Sony Alert Bulletins are about, I couldn't download them!
 
Yeah, I was wondering about them too. I do remember the capacitor disaster, and it may have started about then. I didn't look at the caps while I was in there. I did do the sniff test, and nothing jumped out at me. I'm hoping it is just lack of use and a loose connection somewhere.

The Sony was my last project for the day, and I ended up not having a lot of time, but I wanted to look in case it might help my subconscious figure it out over night. It has happened before. I also wanted to see what I was jumping in to. It actually isn't as bad as some I've looked at. I loved the big blurb up front on the service manual about static awareness and how to handle sensitive chips. I've still got a couple of anti-static mats from my days in the field.
 
Motor in Sony machine would be very LAST thing to consider highly unlikely bearing is problem
I learn smart to not be cheap skate and BUY a GOOD manual if serious about fixing a machine plus has bulletins

Well, I had a great evening! I decided to take it apart again tonight, and then just put it back together in case there was a seating problem with the internal interconnect cables. I put it back together, zeroed the arm, and pressed start, and voila! We have ignition!

I've already played a few albums and I'm really impressed by this tables ability to track even with heavy vibrations!

I have an older house with squeaky floors and that has been a turntable issue. I've had more than a few tables leave the house because I wasn't impressed with how they skipped when walking around. The best up to now has been my B&O 4002. But this Sony is unshakeable! I started off slowly, but eventually I was jumping up and down right beside the table and it wasn't concerned at all! It just kept on playing with no distortion I heard! Wow!
