The problem here will require replacement parts. Welcomejee had posted one of the more common causes of this, but in reality, if the sled gears are clear and in good shape, the motor itself is the likely defective part. This is not a repalceable part from Teac. They will only provide the optical block which includes both the sled motor mechanism and the optics. This will make the parts cost more than the replacement in all probability.

One thing you can try to prive this is to alter the position of the sled in relation to the motor position. Carefully move the sled along its path without moving the motor. WIthout seeing the specific mechanism inside your unit, I can't be any more descriptive, but the gaol here is to determine whether there is a problem with the motor or the mechanism. Because of how the motor is used, a slight "dead spot" inside the motor can cause the problem you are seeing. Basically it works like this:

The motor moves to a "center" position for the track and the lens itself is "tilted" to read the track behind, through the ahead of the exact motor position. When reading ahead, the electronics again tell the motor to move so that the "ahead" position becomes the "behind" position for the next read cycle. This means that the motor only moves a small bit. If a dead spot is hit, additional voltage is required to actually move the motor. When this happens, the motor can overshoot its target. The result of this overshoot is seen as skipping.

Hope this helps a bit.

That could be some dirt on the laser head lenses.
Try cleaning the lens. If you can see the lens when you open it to put a cd in, you can clean the lens yourself with a q-tip. Use a very small amount of alcohol or windex, just enough to make the tip of the q-tip moist, and rub it on the glass lens in a circular motion. then use the dry end of the q-tip to dry it off. You can then try another cd and see if it plays good. If so, you are good to go, if not, you probably need a new laser pick up. If it needs a new laser, you may want to just buy a new boombox. The repair will most likely cost as much or more than a new boombox would.
----------the emitting diode is not shiffting right..it might need some cleaning of its track..open it and check it out.


• Clean the disc.
• Check disc for warping, scratches, or
other damage.
• Check if something is causing the
system to vibrate. If so, move the
system.
• Make sure the speakers are at least 3
feet away or on a different surface
from the main unit.

Hi,
Please take off top cover and check Sled mechanism of Laser block, it has gears and grooves. I'm sure there would some dirt that obstructs smooth sled drive. Clean grooves and gear and then try.
Below is an image of optical block and sled mechanism is marked just to give you an idea.

It doesn't matter which compartment, they rotate over to the read laser. The problem is in the chip that changes tracks. This is a warranty service problem.

I know that's the last you expect from a Fix It site, but sorry, you've got a bad chip.

    Expensive or not, the problem is in the chip not the gears or where the disc is in the tray. The tray just rotates into the the laser read component. The fact that each and ever CD is skipping the same tracks indicates the EEPROM (software written to a chip) is faulty. You cannot address this. I cannot address this, it needs a new chip. So, bad news is bad news. Sorry. We do have to give it now and then.

Check out the connections first and also check the cd holder is it in correct position and also the scratches on the cd this can misread and lead to jumps.

Some of the old soundcloud downloaders don't work anymore, so you have to try some new solutions. There are many websites that allow you to download the music from soundcloud easily, and also browser extensions for both chrome and firefox. It's difficult to download the tracks on your iphone or android but not impossible. There is a handy comprehensive guide here: How To Download Music From Soundcloud Tech Torpedo

Denon CD deck


This unit needs a service visit. It may be a common problem with that model but to me it sound like a power supply issue as when you play a disc more power is used to rotate motors and move the sled. This is indicating to you that it is in a weakened condition and will soon fail more significantly. The problem may be as little as a solder joint or a defective Filter capacitor which is common in some models of equipment.

I Have a Pioneer PD M602 6 disc changer, and I just bought it used. And I cant get it playing. Sometimes say "no disk" ( but the tray is full discs applyed as it schould. It loads one disk after...


To my surprise, CD cleaner disc did it for me. It's a very old Philips one with a bit of furry stuff on the track side. I was amazed it even played, but it did and after letting it run for 20 secs, tried proper discs and it works fine. And this Pioneer PD-M603 is at least 15 years old!Looks like it would be hard to clean the lens manually because it's a long way inside.
