Question about JVC MX-D301T Shelf System

CD fails to start.

At times the unit fails to recognise the music CD in the tray, or recognises its presence and shows tracks & time play on screen but doesn't initiate playing. The fault is erratic. Pushing 'play' on the remote doesn't initiate either.
Is this a faulty head or 'dry joints' somwhere?

Hi,

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.

If still ur problem is not solved then i am sad to say you have to get it repaired and thats the only solution..

Good luck..

Well..that looks to be a clear indication that you have a lens cleaning challenge. Believe it or not, it 's not unlike the old head cleaning for audio and video players. Now, here's the rub, the cleaning kits that are recommended are quite dear. Let me see which ones are available for this unit.

RCA RS2664 Stereo wont play CD in any of the trays but seems to try to scan to play.


Hello
The laser pickup unit's lens may be dirty or dusty. Just put a lens cleaning disc into the tray, and play it at least three times, by ejecting the disc each time, and reinsert in in to. The lens cleaning disc can be bought from most of the electronic spare part selling shops at your town, and won't cost more. If it dose not help you, the laser pickup unit of your RCA device should be replaced with same type and number. OK.

Cd system does not recognise the cds on playing deck.


The unit is a 3 disc changer usually when these kind of problems occur there are quite a number of possible solutions.
When i faced such a problem it was due to the current being low. Then it was 200 volts instead of 220 so check yours and determine if the current is adequate otherwise you can get a voltage regulator.
On the other hand this happens when the lens is dirty or the CD is not properly placed but the second option is usually an off case.
Generally to solve the problem take out the unit from the mains for about 20 mins.
If you have the technical know how you can open the unit and try to clean around the CD tray. This should be done with utmost care as damageable components are around the tray(this is not compulsory if you cant).
After about 20 mins pug the unit back
Next get a CD lens cleaner and run it in the system to clean the lens of the unit.
put in a single disc and attempt to play. At this point the unit should function fine.
Hope this solution has been helpful?

CD playing erratic


Run a "Laser Lens Cleaner" thru the unit a couple times. Use one that takes fluid, you can find them at just about any retail store for 15-20. If that doesn't solve it, it needs to be repaired. At that point weigh the cost over replacement. A new transport usually will cost 100-150 on average for parts and labor. Hope this helps

CD player does not work


10/6/08 Update.
Solved the problem myself.
Repositioned the printed circuit board with the CD Drawer open/close limit switch.
I suspect that the board shifted during shipping and failed to trigger the closed drawer position.
Player is now working.

"NO DISC" reading


Try this CD realignment process built into the Sharp XL HP505: Have unit off.
Hol down the square (stop) button and the X-BASS button while pressing the ON button. This starts the CD TEST. press play, the memory, then memory, memory, memory, adjustment lights will come on the screen. FOF, TOF, TBAL, TGAN, FGAN, RFLS. press cd1 - track 4, press cd2 - track 9, press cd3 - track 15. Press square (Stop).

If all the cd trays are full, then will light up . This worked for me.
