Cue button is going faulty - Pioneer CDJ-800 Turntable

Here are the general steps to assemble the cueing button and place the ball:

1. Remove the old cueing button (if applicable): If you're replacing a broken cueing button, you'll need to remove the old one first. This typically involves unscrewing or unclipping it from the tonearm assembly.
2. Inspect the cueing button mechanism: Take a close look at the cueing button assembly to understand how it works. There should be a small lever or mechanism that controls the movement of the cueing arm.
3. Place the ball: The ball is typically placed within the cueing button mechanism. Look for a small cavity or slot where the ball sits. It's usually a round indentation or a small cup-shaped area.
4. Assemble the cueing button: Carefully position the cueing button over the mechanism, ensuring that it aligns properly with any pins or grooves. If there are screws or clips, use them to secure the cueing button in place.
5. Test the cueing button: Gently press the cueing button to see if it moves smoothly and raises/lower the tonearm as expected. If it doesn't work properly, double-check the assembly and make any necessary adjustments.

If you're still having trouble assembling the cueing button or can't locate where the ball should be placed, it may be helpful to consult the turntable's user manual or seek assistance from a technician familiar with Technics turntables. They can provide specific guidance based on the model of your turntable and help ensure that it's properly assembled and functioning correctly.

You need to take it to the shop and get the switch replaced. It shouldn't cost more than an hour's labor/bench charge and the cost of the switch. Depending on your market probably $75-100.

Seems that the switch under the Cue button is dirty, or broken.

Hi,

It good be a number of things that can cause this, it could be the quality of your cdr's that your using, it could be your disc copier going faulty, it could be your recording software your using, it could be your disc's are slightly damaged, it could be the speed your your copying your cdr's or it could be your laser pick-up going faulty. If you havent had your player repaired you can send it to us to have a look at it for you.

Regards.
Paul.

the faulty button will not stop it from playing well... replacing them is not hard so long as you have some experience with a soldering iron.
Clean the laser lens with a cotton bud wet with windex... then use a dry one to be sure no residue is left. If it still mistracks... new optics required!. You willl need a pioneer service agent to do this for you. A little complex for the first timer :)
