I just bought a Dual XD4MA760 cd player with the 3 inch display. i hooked everything up and the power came on but the 3 inch display came on shortly after for a few seconds when i try to put the cd player in the dash the screen went out and its done it several times and i cant figure out which wire it could be I'am pretty sure i've looked over all the wired to make sure they were connected. Anyone have any idea what it could be?

It sounds like you have the 12 volt constant wire connected but not the accessory wire. 12 volt constant will usually allow you to eject or insert a disc into a radio, even when the car is off, but to actually play anything, you have to have the accessory wire connected to accessory power. Pull the radio out and make sure the accessory wire is connected and getting voltage when your key is in the accessory position (the first notch forward in most modern cars, or the backwards notch in some older cars). If you're not getting power to the radio in accessory mode, check the fuse on the red wire behind the radio to make sure it isn't blown, check the connection of your radio's harness to the aftermarket harness to make sure there is a good connection there. Also, check your fuse panel to make sure your radio's fuse is intact. Depending on the car, you could have other things in the car not getting power that are on the same circuit, such as the dome light, door chime, or 12V charger plug. You could also temporarily splice the 12V and accessory wires at your radio both to the harness's 12V memory (battery) wire, which will tell you for sure that you may not be getting power to the accessory wire, if the radio now turns on and actually plays (even with the key off, b/c the accessory lead would now be getting power all the time.

SOURCE: JVC car radio/cd player wont switch on

As a sanity check run a temporary wire directly from the battery positive to the radio. Twist the red and yellow wires together and connect it to the wire from the battery. If this works either your red or yellow wire connection under the dash or to the harness is not hot like you think. Yellow usually goes to a constant 12 volt source (to keep radio memory) and the red wire to 12volts when the ignition is on. In some radios this is reversed. The test I mentioned will determin if the problem is in the wiring or the radio.

For most Pioneer single CD players, you can set the clock using the following steps:

1. Press and hold the SOURCE button until the unit turns off.
2.Press and hold the FUNCTION button, until display pops up, then release.
(If you do not have a FUNCTION button, then push the AUDIO button)
3. Press the FUNCTION button again until the clock shows on the display.
4. Press the UP and DOWN buttons to adjust the hours.
5. Press the LEFT or RIGHT arrows to move to the minutes.
6.Press the UP and DOWN to adjust minutes.
7. When complete, press the SOURCE button to exit.

SOURCE: cd player plays, but no sound comes out of speakers.

Look at the enwood. I bet you have the remote wire hooked to the blue wire insted of the blue/white wire. The blue wire goes dad when you play a cd as it is for a power antenna. The blue/white wire is your amp turn on.

Now, if you do not have a blue/whie and only blue, then obviously that circuit in the radio is bad in whch case your only other option s are either connecting it to an accesory fuse or using a toggle switch connected to power.

SOURCE: cd player plays, but no sound comes out of speakers.

first off the amp gets power straight from the battery. the amp is used to power the subs. the subs are suppose to be connected to the amp only( never the speakers).

for the second part you mostlikely killed the wires. you should get some one to look at it and check the wires. thee speakers might need to be re-wired

SOURCE: CD player wont come on was doing weird things

You have your accessory wire (red wire) and remote ran together and the yellow (constant wire ran separately in the dash?

You need the red wire to so you can use accessory and to turn off your cd player when your vehicle turns off.

You need the yellow wire to keep all your settings stored. base/treble/time clock

Just a little clarification. Your amp turns on with the remote wire (blue) wire, if that is not hooked up you will get no power to the amp.

Here's the in-dash diagram to your vehicle at the bottom of this pdf.

You want to focus on N,O, and P

Do you happen to have an after market wiring harness? These can be bought from walmart for your vehicle. You just take the male end connect the colors together and plug end that goes to your cd player into the female end. Very easy to do.

You could also have one of these fuses out under your hood, that might cause you to lose power to everything.

How can i make my cd770 unit display time consistently? (bought car at auction, so no remote, no manual!!)

Not sure from description if you've got it wired right, and I am assuming you have most of it working but can't get the time to stay in memory. Are you sure you have the memory power wire going to a constant power source? 1 power wire ( power with key on or in accessories mode) will run player and the other which needs constant power would be for memory and time. Almost sounds like that is missing. Some units will not run at all without both, where others will work, but not store anything such as time, and needs to be reset every time it's turned back on, if that memory wire isn't hooked up.

CDN88 Dual CD Player Display Problem Right Display keeps showing all characters...... It plays fine and the buttons all work. Just the display is showing all characters available....

This could very possibly be a bad internal circuitry problem. A firmware problem due to faulty chip or capacitor or resistor. Testing will need to be performed to find the exact fault. An ohmmeter, vom meter, and cap tester will be needed. Most units are 25-30 ohms and 5 volts of power in each component. A purchased service manual would be very handy.
Have you tried all display settings to rule out settings as the problem factor?

My dual xd7500 cd player doesnt turn on anymore while hooked up only the power button light turns on nothing else works this is hooked up in my bedroom but the problem should be the same as in car can...

Is the red wire in the back hooked up to a power source? You will need that in order for it to turn on. It is the wire tells the radio to turn on when you turn your key.

No Display Lighting

One thing you may have to take a look at is if your dash lights are all the way up. I know with my car, if i have my dash lights all the way down, everything looks like it is turned off but still works. This might also help with night driving and knowing what speed you are going. :)

Same problem as yours with my deck. Bought the deck a month ago, turned car on in the morning face plate does not move down, music plays everything ok but can not access the cd or move the plate regadless button pushing.
Have you tried the reset button? Hold it for 3 seconds ( ball point pen to press the button above power button) U will lose the presets but Oh weel.
I am going to remove power completey from the unit later on today, and if it still has issues I am returning it for a replacement ( Bought it form Best Buy)
