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..

Sorry to hear about your bad luck there. If a hard reset does not work and its not simply the power button is not correctly aligned (try fiddling the pressure up and down if it is loose) then it's likely the device has failed. Even though it's survived other power outages it's still entirely possible the most recent one has caused this failure. I've seen failure of electronics from operating on unstable voltages from solar panels and less than perfect inverter systems and it's always the case that "it's been working fine up until now!"
The display disappears from/does not appear
in the display window.
• The dimmer is set "DIM-ON" (page 17).
• The display disappears if you press and hold (OFF)
Press and hold (OFF) on the unit until the display appears.
• The connectors are dirty (page 21)
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.
the faceplate has a loose or broken contact on one of the wires on the ribbon wire located in back of where the faceplate mount. the ribbon wire is expensive and you must open the radio and install it. the wire is about 30 bucks plus shipping from the dual company or namsung. you can also find the ribbon wire for sale at ebay.com or parts.com
Got to the following lik for your manual:
Refrence page 6 for instructions.
With the unit off, press open to allow the front panel to slide down. Genetly squeeze the release tab located on the bottom center underside and pull faceplate down and away from unit to remove. To install insert left side faceplate first then push right side to secure.
Hope this Helps
This is what the manual says: With the unit off, press OPEN to allow the front panel to slide down. Gently squeeze the release tab located on the bottom center underside and pull faceplate down and away from unit to remove. To install, insert left side faceplate first, then push right side to secure.
make sure that you have power not only to the red wire but also the yellow wire...
one is battery power the othe ris ignition on power. If it only is getting one power it might not think the ignition key is on..
also maks sure there is not a reset button somewhere that you can press with a pen...
To fix the projection display that is stuck with four 8's, hold down the hour and miute button at the same time. Keep the buttons pressed down while unplugging the power source then pluging it back it. I did this and the screen works like it did when I first got it.
