JVC KD-S640 pinout needed

Sounds like you have a loose wire. check them all.

Take a torch and see if there are any foreign objects in the loading compartment. Children are know to insert for coins to just about anything they can squeeze through the ****.
Then try removing the system from the dash and open the top lid. see if you can clean the lens from a small cutout on the loading mechanism using a cotton ear bud. Do it in good light because the lens ( looks like a fish eye ) can oly been seen at an angle through the cutout.

hold the reset button with a pen tip for 20 secons and it should be back to normal

Its dirty, try a disc cleaner, (brushes not solution) and if that does not work, its time to replace, (unless the radio is all ya want).
ALSO- if you are trying to play burnt discs, (cd-r, mp3 discs etc) than that could be the issue as not all indash cd players support non store bought cds

Usually it's....

black = ground
red = switched battery power
yellow = constant batery power (for clock...etc)
orange = illumination
blue = amplifier turn on or accessory (electric antenna, amps etc)

green/white/purple/grey are speaker wires.

Change the audio amplifier IC maybe are damaged

A4 Yellow - Always on B+12 (such as the battery's positive terminal)
A5 Blue/White - Power Antenna
A7 Red - Accessory or switched +12VDC

B3 Gray - Right Front +
B4 Gray/Black - Right Front -

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FIXYA.

Same issue but pressing Power and SEL would not reset unit. Found solution. Once again disconnected the car battery. Removed the face unit from the radio base and then reconnected the battery. Replacing the face unit AFTER the power was re-established solved the issue. (Probably pulling the radio fuse rather than toying with the battery connection would have done the same thing.)

hit the power button. wait till it says ATT or something like that then hold select then use the volume to change time and up/down to change Minute.Hour.


i had this same problem
