Not sure what kind of car you have but,,, just for the heck of it, when you turn on your lights , try turning your interior dimmer all the way up. If the radio works again, then you have it powered from the wrong wire in the dash. It needs to go to a constant hot (12V) and Accy/ignition (12V) and not to a lighting wire which would power the back lighting of a factory radio.

Either you blew the memory fuse or didn't connect the radio to the proper wire. Check fuses inside and under the hood.

The memory wire to the radio needs 12v all the time. If it's not connected or no power at the lead the radio will reset every time you turn off the car.

I have a 2007 dodge ram 1500 3.7 v6, I'm having trouble with my pioneer stereo! I have everything perfect but when my stereo goes off it resets! What color is the memory wire?

It is usually called the remote wire. Either solid light blue or light blue with a white stripe. On the back of the pioneer deck look for the wire labeled REM+ it's just a 12v constant.

Apparently, you have no power at the 12 volt battery/memory wire at the radio harness of the vehicle. This wire is white with blue in color.
Also, based upon your description, you have connected the battery/memory wire and the accessory wire of the radio to the 12 volt accessory (switched) wire of the vehicle. This wire is white with red in color.
Check the radio/ stereo fuse of the car. You may have blown the fuse during your installation.
You have no memory at the radio because when you turn off the key, you lose all power to the radio.
Also, I mentioned the wire colors just in case you used an aftermarket radio wiring harness. Make sure that the yellow from the Pioneer unit is going to the battery power source and, the red of the Pioneer is going to the switched power source.

The speaker output doesn't work

Hi Marlena,
I had the same problem with the 2200ub, so I will post the solution for that. Hopefully its the same for you, if not sorry I couldn't help better.
I have a 2002 Suburban and was installing the Pioneer DEH-2200UB. The suburban had the factory stereo still and has onStar. So I had everything hooked up, purchased the harness which was perfect except for the blue and white wire on the stereo and a solid blue wire on the factory stereo end. I was confused by there being 2 plugs from the factory stereo and one for the 2200.
I finally went to Best Buy and talked to their tech and he told me that since I have onStar I need to cut the pink wire and wire it to the blue and white wire that goes into the new stereo. These guys were great they didn't hesitate to tell me how to do it and even gave me the extra wire and connectors I would need to do it. Best Buy is expensive but I will keep shopping there just because of their service from these kinds of people.
The pink wire is hooked into the amp which I believe is located under the drivers seat. As soon as I did this everything worked perfectly.
I am not sure if the onStar still works, but I don't plan on using it anyway so if that is important to you, you should probably have a pro do the install. Best Buy will install it for $50 (plus parts) but it could be more for dealing with things like this I really have no idea.
Hope this works for you.

Klipsch subwoofer doesn't work with Pioneer receiver

Make sure the subwoofer is hooked up correctly and powered. Also, be sure to make sure the subwoofer is turned on in the Head Unit's settings which can usually be accessed via a button on the face of the Head Unit.

Best Regards,

Sound shuts off, sub still works

That is a common problem with this radio, for it can not go to loud without going down in volume or shutting down.

Overall Problem - Panasonic RX-ED707 won't work properly at all

only 1 reason for that faults :

there is a flat connects the top panel which has all the controls with the other circutes in the stereo...
so you have to open it and care for the cd unit it damage easily then check the flat for loseness or cuts
it happened to me also and that works perfectly
good luck
