KCD-X590 is looking for a code that i never put in, and i bought the deck brand new
Every time i turn on my deck via source button it says "enter code - - - -" i never put in a code, i have asked the tech that i paid to install the deck if he put in a safe guard code and he didn't either, i went to a service center and paid 40 for the guy to work for all of 10 seconds and he immediately fixed my radio, i want to know what he did. thanks.

Method of clearing the programmable security
1. While "– – – –" is being displayed, press [->> ] key for at
least 3 seconds while pressing [AUTO] or [TI] key.
This makes "– – – –" display disappear.
2. Using the remote controller, input "KCAR".
Press remote controller  key 2 times (Input for "K") and
then press [->> ] key.
Press remote controller  key 3 times (Input for "C") and
then press [ ->>] key.
Press remote controller  key once (Input for "A") and then
press [->> ] key.
Press remote controller  key 2 times (Input for "R") and
then press [->> ] key.
3. The security is released and the unit enters the STANDBY
4. If a wrong code is input, the unit goes into the Code Re-quest

A couple things may cause this: If a speaker wire shorted out (either a voice coil or the wire itself is grounded; touches the vehicles chassis ground) Solution: disconnect each speaker from the deck and see if it turns back on. 90% of the time thats the problem.
I do not think your use of an equalizer has caused any problems. I will explain the proper use of the source/direct button. This button's function is to monitor the output of a recorder connected to the record outputs of your amp. When this button is pressed on the sound going to the speakers comes direct from the "source" (cd, radio tuner, phonograph etc.) when in the off position you can monitor the recording of whatever source is being recorded via the tape deck. This switch must be off to record through the amps record outputs.
To test this, put a blank tape in the tape deck, choose the source as phono and place the dec in record/pause. With the source direct button pressed on you should hear a change in volume when moving the amp's volume knob only. When source direct is off you will be able to hear the output of the tape deck, so adjusting the tape deck's record level will also affect the volume coming out of the speakers. more record level in/ more level out.!
Below is copied from page 9 of your user operation manual for Marantz's explanation of the source/direct button.

your amp turn on is hooked to the power antenna wire. Swap the blue wires and youll be good to go. Since the power antenna is not needed, when the radio goes off tuner, the 12V signal is turned off. and your amplifier will also then lose its remote turn on.
Reverse the 2 blue wires.
The first thing to check would be the voltages on the speaker wires. They should be about 6.5 to 7 volts on each wire. Then check the surface mounted resistors on the front right side of the main board. Take out the CD deck and reflow the solder on them. Make sure you do this part with no power source connected. The surface mounted resistors have "2R7" on the top of them and are located in the right front as mentioned before, while looking at the unit from the front facing you. If you do not find the surface mounted resistors it could be that I am thinking of another model of Kenwood, but I am pretty sure they are also in this model as well. Use just a touch of solder on each side of the resistors, there are about 6 to 8 of them all connected in series. After that, reconnect the CD deck and connect the power source to the red and yellow wires and the black wire is your ground, connect that as well. The display should light up. Let me know what you come up with on the voltages of the speaker wires and if the display starts working again. I do not have access to my service manuals at this time, it may be about 2 weeks before I can get them. So I may not be able to get you completely fixed up until I can get my service manuals. A schematic is sometimes the most valuable tool when fixing electronics.
The problem is not the faceplate for any of you, it is inside the main unit. If you know how to solder, you can fix is very easy. First take the top off the unit, there is 1 screw in the back middle. Then take the CD player out. It has 2 screws holding it in at the front corners at the bottom of the CD deck. Use a number 2 phillips and take out the gold screws holding the CD deck in place. Then you can pull out the CD deck, and be careful not to damage the ribbon cable connected from the CD deck to the main board. The deck can just sit up and over to the left to get it out of the way for what needs to be soldered.
Look inside the main unit on the board and you will see in the front right corner a series of surface mount resistors all connected in series. Just reflow that solder on them with a small amount of new solder added and the display will once again work perfectly. That solder is very heat stressed, that is the problem. I have fixed dozens of these over the last few years. Make sure you put it back together the same as it came apart, and you are done.
