Tascam CD A500 'No Disc' error message


The first thing i would suggest you to do is a hard reset by unpluging the the player for 30min and then try again.

If this does not solve your problem then please see if the player tries to read the disc.
Load a disc and listen.Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable.

Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word.
This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces.

You could try to clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try.

If you actually see dust on the lense, then its just that simple. clean, close, play.

It may also be worth your while to check on the small shafting that guides the carriage of the laser pickup. Dirt, grome, dust and solidified lubricant can cause stoppage of the carriage and the laser eye then fails to read the next track.

If the problem does not get solved then you have to get it repaired.

Please don't forget to rate the solution.

On my CDP-CX300 It will not play comes up with "Disc loading error" on the display, turntable and loading mechanism seems labored suspect power problem ? any suggestions ?

1. Chances are real good that the laser lens has gone out or is too weak to read the disk. It's a maticelous procedure to calibrate a laser lens. It may just need to be replaced.
2. The labored mechanism is due to the belt in the disk drive being dirty or stretched out. With this the mechanism can't inject far enough for the laser assembly to come up properly far enough for a good laser alignment therefore giving you the disk read error. You can clean these drive belts with alchohol and put them back in. While it's out check the belt for cracks. If there are any replace it. Or if it seems stretched out, which you can tell when it's around the pulleys, replace it. This belt is located in the front and under side of the disk drive assembly.
I've had the same problem with Xbox360 drives and the above solutions worked out quite well. But I haven't worked on one of these devices yet.
3. As a last thought. There may be a swollen capacitor on one of the circuit boards that may be causing the problem. A cap swells and shorts out. If so it will need to be replaced. I've had single swollen caps keep an entire television from working.

My hk 30 player tray flashes (disc error) with every digital audio disc. help

Often times the tray and pickup lift assembly are related and there is a cam alignment. IF you pulled out with force the tray the alignment may have been upset to where the cam is not completing the lift of the Pickup and if not in the right position the laser will not be able to focus. The correct solution is at a Technicians bench where a new belt could be put in, lubrication that is required and some cleaning will be done.

How do you replace a pioneer cdj 500s laser pickup correctly. Please give as much detail as possible as i have replaced one but its not reading the disc properly

Unfortuneately you should have replaced the whole laser pickup assembly, they come pre-aligned eliminating special test equpment that would be required when single part replacements are done.

Error message (protect) cd plays then goes silent then plays again. have cleaned laser several times with cd cleaner disk.

Dirty lasers don't cause "protection" problems. Are you sure thay message is displayed on the CD player? That word is nowhere in its manual.

Fisher tad m70 10 disc cd player compact disc searches and won't play a disc, no disc found

I have that same model bought new in 1993. Once I had the same problem - I used one of those CD cleaning disc left it unplugged for a few hours and then it worked. But if the laser needs alignment - then it needs to be re-aligned/serviced by a tech.

CDJ Laser Alignment/Calibration

They dont normally go out of focus, any trouble reading discs / freezing is usually caused by a worn out laser which will require replacement.

Getting errors reading the first (data) track on mixed-mode CD, what can i do? get error message "TABLE ERROR"

The CD Player platter does not spin or displays Table Error.
Follow this procedure when the platter of a CD Changer does not spin or displays Table Error.
  1. Open the door to the unit.
  2. Press the center button in the Jog Dial, and attempt to remove all the CD's in the unit. NOTES:
    • Verify that all the discs that were installed in the unit are removed. If all the discs do not come out, the unit will need service.
    • If the player is not operating correctly, reinstalling CDs may damage the CDs.

  3. Attempt to rotate the platter with all discs removed. If the platter rotates, install a few discs to verify operation.
  4. If the platter does not spin when the unit is empty, service will be required.
Also are you getting any other specific error codes, if so, please let me know what they are.

Please get back to me and let me know any other specifics.
Please don't forget to rate this. Thank you!
