Can anyone help. My car stereo has lost its power. There is power to the unit, both on the constant battery and ACC wires and through the in line fuse. The unit just will not light up. Any ideas please?

I have a similar problem with My KDC-X815. There was power all working fine, then the illumination dissapeared and after a day or so nothing, there is power to the unit in both pos and acc. I have given the contacts a lil clean behind the face plate and hit the re-set button on the fron and presto she came to life, for only five mins. Then back to nohing. Th face plate turns when acc is on and off so behaves normally. But I have a blank screen.
I am pretty sure the problem is in the face plate contacts or the plastic cable strip with all the connection.

Wiring harness you hooked it up wrong i cannot stress enough that messing with sterio's by self will mess up factory cars harness take old harness out redo the wires make sure there hooked together right if you have too just take it too any car sterio installers and they will splice the wires together for 5 bucks the right way so all you have to do is plug in and mount back up
quite possible that there is a loose connector wire on the back of sterio or the face plate isnt attached all the way to make complete connection sometimes wires just come loose or were installed loosequite possible that there is a loose connector wire on the back of sterio or the face plate isnt attached all the way to make complete connection sometimes wires just come loose or were installed loose

You may have a problem with the faceplate connection not making good contact. Tell me what model Radio you have, that will help in determining what is wrong. Thank you.

Have you connected the aftermarket unit properly? If you have hooked the main power up to a permanent live power in the car it will continuously draw power. Only the memory wire (yellow) should be connected to a constant power, the main power should be from an ACC switched power. If the radio has been installed correctly there will be no power loss while the ignition is off.
The accessory wire is suppose to be hooked up to your ignition wire and not a constant 12 volt power source. Hooking it up to your ignition wire will only give the stereo power when your key is in the accessory position or in the running position. The constant power source that you mostly connected to is meant for the memory wire on your stereo which will allows it to save your setting when you turn the vehicle off and your stereo kicks off. Otherwise you will end up setting the clock and adjusting your EQ every time you turn it on.
well it sound like your ground wire is not connected the properly way this wire is black make sure
the other 3 are connect right are Yellow is constant power ,Red is acc.ingnition,Blue is the remote.
that would complite your conection done.
I have a Sony CDX GT 530U. I had a problem with no display and I thought no power period. I did not try to install a CD, so maybe I did have power to the CD motor but no display. This was frustrating because I could get the old factory Nissan radio to power up and work so I thought I had a dead Sony unit. After a lot of monkeying around, I discovered I had blown a fuse while installing the unit (you should disconnect the negative terminal of the battery when installing the radio... which I thought I skip, that was a no no.). I had checked the auto fuses, those cheap little plastic fuses behind a panel below the stearing column inside most cars, at least all the fuses I thought went to the car stereo. Turns out I missed one that was labeled "Batt" or something like that, which was the constant power wire to the car stereo. There was another fuse for the Accessory power to the car stereo (the main juice went the key is tuned to ACC or Start position). Turns out the Sony unit display runs off the constant power, or at least the unit on/off button runs off the constant power wire, so even though the ACC power wire was live, the Constant power wire had a blown fuse and the unit would not turn on. Check all your fuses inside the car, I bet that's your problem. Constant power on my Nissan Sentra was a 7.5A fuse, while the ACC power ran off a 15A fuse, but your vehicle may vary. Good luck.
first red is ignition or acc (turns off and on with the key) yellow is constant power (always hot keeps memory) orange is illumination (lights up radio) if vehicle doesnt have a seperate illumination wire connect it to the ignition wire. now process of elimination your ground is correct because it worked with all wires to acc your acc works because u had all them connected to it and it worked your problem is in your yellow or constant/memory i suggest u test it again take piece of wire any old thing long enough will do and run the wire directly from the battery under the hood and just run it outside the car through the window and connect it directly to the yellow wire make sure u have a good connection at the battery on the positive side if u have test light or volt meter test the wire before connecting it to the radio if it works then u know there is a problem with the wire from the vehicle (fuse wrong wire bad wire ) if it doesnt work make sure ground is connected tight and that paint is cleaned of the surface where ground connects and that the yellow wire to the radio is tight in the back of the radio.
The 'illumination' wire is to hook up to your headlight switch to back-light all buttons when headlights are on. The pink and black audio interrupt I believe is for hands free cellphone communications it will cut out audio when you have a call and have your hands free hooked up through your stereo. The remote turn on is for external amplifiers it provides a small amount of power to to turn on/off external amplifiers. As far as your unit not working I would make sure you have a sufficient ground using a voltmeter and make sure your battery lead is fused and fuse is not blown. You should have a memory lead(maybe yellow) that need constant 12v and a ACC power that needs switched power that is only on with key(usually red). Hope this helps! :)
The correct wiring is constant power on the yellow wire, switched power on the red wire. I'm not certain why you weren't able to get it to work in this configuration; the unit needs power on both wires before it will turn on, but if you lose power on the yellow wire the settings will be lost.
