Question about JVC Car Audio & Video
We were told to press the reset button 3 times - this does not work. I've also disconnected the unit and placed it into another car - it still does the same
Not sure if this will help any other owners since my answer is 4 years late, but this is what I found from another user. Apparently if you mess with the wiring too often, it goes in a safe mode which you need to do some button trickery to unlock the device from it's safe mode. These are the Steps.
1.Disconnect power supply
2.Press [MENU] and [UP arrow] buttons and keep holding.
3. While holding the buttons [MENU] / [UP arrow], connect the power plug again
A. The display will show "DC ERR"
*** if it still shows "Chk wiring ..." repeat the steps above until you get "DC ERR."
4. Press [UP arrow]; the display shows "DC1 ERR"
a. Press and hold [UP arrow] and it will show "DC1 OK"
5. Press [Down arrow], the screen will show "DC2"
a. Press and hold [DOWN arrow] and the display will show "DC2 0"
6. Disconnect the power from the back of the unit.
7. Remove the Face Unit.
8. Reconnect the power from the back.
9. Use a sharp object and press the [RESET] hole for 3 seconds and release.
10. Reinstall the face unit and turn on the power.

It sounds like the internal output IC is bad. It would need to be replace.

Do you have a "RESET" button on your stereo? Check your owner's manual to find it. I have a JVC unit in my car and the reset button is a small hole behind the detachable face. Take the end of a pencil or a pen and insert it in the tiny hole and hold for a few seconds. This should reset the stereo so you can get the CD out. Hope this helps...

Try disconnecting your battery, reconnecting it, and resetting your stereo. If that doesn't work, the constant power (yellow wire) or ignition wire (red wire) may have come in contact with ground or isn't properly connected. Make sure everything is connected properly and try resetting your stereo. If it is still flashing "protect", the unit needs servicing Contact JVC Customer Care Center at: 800-252-5722.

The Touch will not work with the KDPDR30. I spoke with JVC and their models that will operate the Touch are KDPDR40, KDAPD49, KDPDR45, KDPDR41 and KDG47 the last two have a cable required.

Check your wires they might be touching steel around your car mostly look at your yellow and red wires those are the 1' that give it power and light to your radio also check your radio fuse in the back.

This is the procedure I used for an MP470. It is basically a modified version of that previously posted for the MP460.
1. Disconnect the power cable.
2. Hold down "On/Off" button.
3. Reconnect the power cable.
4. With the power button still down, press the "Stop/Reset" button twice.
5. Release the "On/Off" button.
6. The printer is now in "factory mode".
- wait until "idle" is displayed.
7. Press the right arrow button (next to the "OK" button) repeatedly until "Shipping Mode 3" is displayed.
8. Press the "OK" Button
9. Wait until "Without Cleaning" is displayed and then presss the "Stop/Reset" button once. (I pressed the ok button after Stop/Reset button on my MP470).
10. A test page should print.
11. Open the cover.
- the cartridges should position themselves at the far left - the cartridge removal location.
12. Disconnect the power cable.
13. Remove both cartridges.
14. Close the cover.
15. Reconnect the power cable.
16. Press the "On/Off" button once.
17. Wait until a "Replace Cartridges" message is displayed.
- insert cartridges.
18. Wait until the printer is operating in its normal mode. The display shows the normal start menu (ie: Copy).
The ink levels have been reset.
