Power on problem for XD7500

Unit will not power on. Faceplate stays lit even with ignition sw. off. All segments of panel are lit. Power button does nothing. All functions do not work. There is probably a bad circuit component. Anybody know which one?

Re: Power on problem for XD7500

Hi. You need to check a few things. make sure you have power on both the red and yellow wire with the key on. If only one has power the radio will not work. If the red and yellow wires are switched it can also affect the way the redio operates. One is constant power for memory the other is key on power so the radio knows to shut off with the ignition key off. also make sure that you have a good ground connection on the black wire.. if nothing works yes you probhably have a bad radio. the dual brand radios are notorious for poor solder connections on the mainboard due to the way they build thier cheap circuit boards..

I just Spoke to tech support. This is what they said:
1. Key in the on position and the red power button lit, remove the face plate.
2. On the left bottom side press and hold the reset button, with a pen, for 10 seconds and let go. The red led on the right should flash.
3. Reinstall the face plate.
4. Push power. The unit should come back on.

Mine worked, and i was about to tear it out and return it. So try this first or even call tech support for Dual 1-866-382-5476.

Got power to cd but no display

One idea that comes to mind is,if I remmeber correctly, that model has a removeable faceplate, try this, remove the faceplate,take some denatured alcohol on a Q-tip,clean the electric contacts on the back of the faceplate and also on the front of the deck where they mate together repeatedly for about 4 to 6 times letting them dry between each time that you swab them clean, then replace the faceplate onto the deck being sure that you are seatting the faceplate completely and properly.
This has worked for me sometimes and sometimes not, its worth a try.
Good Luck !

New KDC-135 has Power but Faceplate won't light up

you shold always twist the end of the wiring together and tape them never use connectors, remove the connectors and twist the wires driectly to each other and tape them wiht electrical tape, the connectors almost always can not deliver the proper voltage..

Did you make sure you have the yellow to a constant connect wire and the red to a turn on?if not this can cause the radio not to work......

you can test wich is wich by turning the key off and putting the yellow to the one you think it is and red to the one you think it is, if you have have it right you will hear the CD player make a click run sound...... if not you will not hear any thing.

Kenwood KDC-X717 - Facplate opens when powered on, stays open. No display.

I've had this problem before. The ribbon cable needs to be replaced. They wear out every few years. Take it in for service. Or do you want to sell it? I need the face plate for mine.

Head Unit going goofy

If the unit has a removable face take a pencil eraser and try shining up the little contacts on the back of the face and the radio. See if that cleaning helps.
