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..

Most likely, if power *is getting to the unit*, (there are lights lit on the washer), then the culprit will be a shorted user interface board(control panel). This is a fairly common type of issue with dishwashers. The soft-touch buttons or the touch panel has a shorted button or area(depending on the type you have) and nothing else will function because the unit thinks you're still pressing a control button. Also, a VERY common cause of this issue, aside from moisture or bugs, is a power outage damaging the console when power is restored due to a surge. After an outage where damage occurs, the symptoms don't usually start for about 3-4 weeks after due to damaged chips on the board starting to fail.
Press and hold MODE and then press PRESET 1 to turn on or off the clock display priority. This should allow you to set if the clock stays on while the unit is off.
Aside from this, you may need to double check your wiring, specifically the RED and BLUE wires. The RED needs to be connected to a switched source of power and not directly to your battery/etc. It needs to be a source that is only ON when you want it to be ON (such as the ignition on wire). The YELLOW wire is the only one that should be connected directly to your battery.
Double check the BLUE wire is connected correctly to your AMP as the AMP running all the time would kill a car battery overnight where-as the stereo clock display alone should take many days to kill a properly functioning car battery.
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!"
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
