You will have to remove the bottom cover and pull the center post off. There is a set screw that holds it in place. Once removed you will need to clean the hole out of dirty grease and oil with a q-tip and alcohol. Then put some new oil in the hole. Just a small amount. Sewing machine or turntable oil or similar. Not motor oil! When put back together that will cause the platter to rise up and away from the base. You may also check the plastic gears under platter attached to the post to see if the are broken or cracked. If it is you have a major problem and it will need to be replaced with a donor part.

If it says your speed setting in on 33, than you have a problem with the speed control inside of the turntable, there is not much you can do in that area. 33 is the slowest speed too, so it seems like it is stuck on 45 or 78. Call Teac if you are still under warranty.

The turntable motor might be the problem, if the grease is old it becomes hard causing the turntable to run slow, by your description we can rule that out since you indicate it runs to fast. therefore it is the voltage that powers the motor with a regulator "keeps voltage constant" or the motor itself will be the problem. The pitch control allows a small change in speed when required.

Canon clc3900 error e013-0002


Hi
In most cases that means that you need to clean/ replace waste toner container, but in worst case scenario:
E013
Cause • Waste toner feeding motor (faulty)
• Waste toner feeding screw (rotation fault)
• DC controller PCB (faulty)
Description
0001 The rotation speed of the waste toner feeding motor has deviated
from a specific value for 0.1 sec or more (PLL signal ‘0’).
0002 The waste toner lock detection switch (SW4) has been pressed for
0.1 sec or more

Teac turntable plays too fast


This sounds like a motor speed control problem. It could be either the motor itself or an electronic fault. So unless you know a bit about electronics and know how to use a soldering iron etc, then the answer to your question is no.

My TEAC P688 is stuck in chipmunk mode for a large record - how do I slow it down?


Sometimes on the base of the turntable (under side) there are two presets one for the 45 speed and one for the 33. They might be hidden under a label or something. You might even have to go inside to find them. Anyway a small flat head screwdriver inserted in it should adjust the speed. You might have to work out which controls 33 speed. And of course if it is below you will have to figure out how to adjust it with a record playing. "Get out and get under!!!!" as they said about cars!

Turntable not turning to play record............. power on............ please help my email address - diatmesa@aol.com


This could be many things like the following>

If its a direct drive turntable the motor could be "blown",
or motor electonic speed controller burnt out.
If its a belt drive turntable then the belt could be broken
or stretched and is slipping, or the belt can have dropped of a drive pullety.
Also there are speed control mechanisms to adjust the final speed of the
turntable to the recorded speed of the record like 331/3rpm, 45rpm 75rpm
These speed reducing mechanisims can slip and cause the turntable not to turn..
There are also other mechanical bits that slide and push against each other,
and these can get sticky and the friction increases so much that the power
from the motor drive causes the belts to slip, so you need to identify if a
friction problem exists as well..

If you are carefull you can look your self and find out which one of the above it is.

Be warned there are lethal voltages inside the turntable which can kill you....
so please dont have the power on when making any inspection or adjustments.

Cheers From YUBEUT..

i think it is a belt driver table. you can find a replacement belt maybe. but if it is servo controlled motor driven then adjustments to sped setting has to be done.
