Regarding this manual, does anyone have it?

Ours stopped playing cd's, and i opened it up to see why. the mechanism to load cds is fine, but when it comes to playing the cds, the mechanism does not even spin, and the laser just keeps bouncing up and down for a little.

thanks in advance!

A common fault on the JVC MX-D4T is the cd player, it seems that the lens loses focus or a component in the lens control changes tolerance,(please follow any precautionary measures when dealing with live electronic components).
Anyway power on select 'Disk 3' button,this will bring the laser and disk drive mechanism to the upper level of the machine for easy access,eject the disk tray to keep the mechanism clear, then unplug the unit to avoid electric shock but do not turn off power by the panel switch as it will close the draw.
-Remove upper cover-6 bordering screws at the back and 2 on the front left & right sides.
-Now consentrating on the top part (CD unit) you will see a black plastic moulding in the centre,this is retained by a small brass screw to the left and has a hooked metal wire attached to it in the front, remove these and remember how it is fitted and slide the plastic moulding out to the left and up.
-You should have a clear view of the lens unit, you should also notice a little yellow plastic adjustable resistor screw.
-Now lift the frame that it is mounted on from the back as far as the leaf cable will allow-gently and with a small watch repair screwdriver turn the resistor type adjusting screw clockwise (from view of the screw) by 10 to15 degrees.
-Place the mechanism back into position-this should fall quite easily back into position with its floating rubber mounts.
-Replace the plastic moulding paying particular attention to the white plastic spring loaded mechanism that is mounted to the front end of the machine- the plastc moulding should go under this mechanism too.
- Replace brass screw and metal wire into the same position as it was.
- Replace cover
- Plug in power
- Eject any cd tray and load a disk to test.

This worked like a miracle for me, if yours did not work, try adjusting the lens screw abit more or less.

Good luck
