How do I remove the Numark TTX platter

I have the well documented platter speed problem. I have new drive chip BUT I can't see how to remove the platter to get the backside of the motor board. So far I have removed all covers, undone the spindle grub screw underneath encoder cover.
Platter still will not come off easily.
Am I missing something?

    Hi,

    My TTX variable torque platter will start fine and then most of the torque will suddenly disapear. I hear that this is a common fault, a new IC ? Where can I source this please?

Nope, nothing to it. The platter is just held down by gravity. Take a mallet or a piece of 2x4 block, and give the spindle a little whack. Not too hard, just enough to break the hold.

HOW DO FIX MY NUMARK TTX MOTOR?


if you know how to solder its most likely the toshiba chip under the heat sink, here is more in depth, i wrote this up about 3 to 4 years ago

Ciscoel Nino - "since numark fixed thier overheating problems by adding avent under the platter, i think that what is happeing is that our DCMOTOR DRIVER IC (Toshiba TA7259P) has gone bad what i am going to do itorder this, install it and let you know the deal. there only 5.80 apiece and shipping is like 8 dollars. ill get back to you. I amguessing it is sort of like computers CPU, like its got thermal gel/grease on it and all that fun stuff. It is on the Motor's board heres the image

after i install it too, i am also going to cut vents like this under my platter like the updated versions

(IMG:http://img97.imageshack.us/img97/8523/ttxvents8pn.jpg)


also take your time when installing the chip.
1. its sensitive to static.
2.buy a low heat soldering iron.
3.do each solder point at a time, wait a few seconds for the IC to cool off. then approach the next.
also open your ttx and see what exact IC you need. Mine was a Toshiba TA7259P. Also when you order that, order small tube of thermal paste.

Numark TTX-1 turntable starts slow but then is okay.


A drop or two of light oil at the center of the spindle will surely solve the problem.Remove the platter and check if its clean

Numark ttx wont spin


some tables require the tonearm to be over the record area before the patter starts to spin. If thats not it, have you tried "jump starting" the platter with your finger? the direct drive "stepper" motor might be confused as to where it is at the moment. and finally remove power from the wall for a few minutes then retry.

More than likely the drive IC (integrated circuit) has shorted, and needs to be replaced. Not an easy fix, and you'll have to take it to a service center for replacement.

This is a common problem on this turntable.

Numark TTX1 Turntable Problem-Platter stops


This is a drive issue. Unfortunately the TTX direct drive system isn't the greatest. It's good, but it's no Technics 1200. The only way to 'fix' this issue is to have a professional look at main circuit board to see if there are any components which are burned, or damaged in any way.

Hope this helps some.

Just so you know, there is no actual 'motor' driving the platter. It's a direct drive unit, so it's made up of various circuits driving the unit.

With that said, anyone of those circuits could have gone bad. The good thing, is that most of the circuits (resistors, IC's, capacitors, diodes, etc), are relatively cheap ($2-10), the bad thing is replacing them, and finding out which ones are faulty. You could usually tell which resistors are burnt or caps are blown, but it's harder to test the IC's without the proper equipment.

This is not a cheap turntable, unless you think $300 is cheap for a turntable. Repair wise, your probably looking at about $80-120 for parts and labor. It's a well build turntable, and I think worth investing in trying to get it repaired. Just make sure you get an estimate before any work is done.
