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?

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..

Does the lights indicators light on when charging battery my ion block rocker bluetooth portable sound system being off

that is the most confusing piece of written English I have seen for a long time :>D

If you mean 'does a light stay on when I am charging'? The answer is yes. Here is your manual answer.

Charging Indicator: With the battery charging indicator, when the power cable is connected, movement of the top battery segment shows the battery is charging. When fully charged, all battery segments will be lit without blinking. When the power cable is disconnected, the battery segment shows the level of the battery.

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.
