Question about Kenwood KDC-X590 CD Player

2 Answers

No display and trying to find resistors.

We have the main unit open. We can't see any resistors that are burnt out and we can't specifically locate the resistors for the KDC- MP632U display. Can you please assist? What are the numbers for the resistors?

They are surface mounted and are located on the top of the board in the front right area with the face of the radio towards you. They do not look burnt or anything like that, they just have some heat stressed solder on them and they are not the shiny silver color that solder is supposed to look like. They are small rectangle shaped about an 1/8 of an inch by 1/4 inch (estimate, not exact size) and are all connected in series. They start at an area that is right next to some white glue that holds another component to the board about two inches from the front of the board and less than an inch from the side of the board. You will see two of them right there and they are all connected to one another going to the front of the board. some are mounted in one direction and some in the other direction. If you would like, I can post a picture for you later today with the proper resistors marked for easy identification. Just let me know by addressing your next post to me.

DISPLAY ON MY KENWOOD STEREO STOPPED WIORKING


Hi there,

I also created a tutorial on fixing faceplates with 2R7 resistors (refer to my tip).

But, your unit will have a different chassis, as the faceplate is also a video display.

First you need to determine if the buttons on the faceplate are operating the various functions. If the buttons are NOT operating, then the faceplate itself (or connection to the main unit) can be considered faulty.

It's highly probable that the RIBBON cable (which connects faceplate to the inside of the unit) may be defective - this is common in some Kenwood units.

Try searching Google or youtube for ribbon cable repairs etc.


Hope this leads you in the right direction.


Cheers,

Scott

Most likely the backlighting has burnt out. Repair or replace if not under warranty.

Kenwood KDC-X590 Faceplate display problem


Yes, the problem is inside the main unit. I have fixed hundreds of these radios over the years. 
The solder on these resistors get heat stressed and stop conducting properly. They just need a tiny little touch of solder. 
With the radio in front of you and the face is facing you, take the top off and remove the CD mech. The CD mech can just be set over to the left a little and the ribbon cable to it can stay connected. Just move it out of the way gently. You will see a series of resistors in the right front corner area of the main board on top. They have 2R7 printed on them and there are quiite a few, all in that main area. Just resolder them and put it all back together again and the display will work normal.

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.

KDC-MP532U display blank


Solution from Tech48:

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.

Display on Kenwood Out


I am not sure exactly what solution you are reffering to, but the KDC-MP532U has a problem with the display going out that is the result of heat stressed solder on the main board. The surface mount resistors that are located on the right side near the front of the unit, as you look into it with the display facing you, are the culprits. This is common in about 3 or 4 Kenwood models. These surface mount resistors are on the top of the board, so the board doesn't need to be taken out to fix it. Just the CD mech does. The surface mount resistors just need the solder reflowed, an easy enough job if you know how to solder. They are all lined up connected to each other, I don't remember the reference numbers, but if you can recognize what a surface mount resistor looks like, you should be able to find them very easy.

Thanks for the compliment on the other post, it is appreciated. A good rating would also be appreciated.

Thanks and good luck,

Dave

Light faded out on face plate X590 kenwood


Here is the solution:
There are a series of surface mount resistors in the front right corner of the main board on the top side of the board. Front right while facing the unit looking in. Those surface mount resistors need to be resoldered, they are heat stressed. If you know how to solder, go ahead and do it. If not, I adise you to take it to a shop to have them reflowed. There are a line of them all in series with each other in that right front corner of the main board. That is the only way to fix this problem, have the solder reflowed.

Kenwood dpx-501


I just solved the problem with my kenwood dpx mp 2090U - (looks similar with 501). FL Display with single CD, USB, 2 Din.
I should share this......... as I received the clue from someone that share the same case to me . Thanks to Mr,Nasirbaek from Indonesia,
The problem is at the main board . Dry (bad) soldering occurred. There are more then 5 resistors in series configuration. The resistor is quiet big (1.5mm x 3.5 mm, surface mount type R) about 2,7Ohms.The position is start from near usb port cable and ended to near big transistor (1 x 1.5 cm power transistor). After resoldering check with multitester to make sure that all R are connected in series configuration.
Just open 3 screws to access the main board. 1 at the top case. 2 at cd assembly, then Carefully take out the CD and the CD ribbon cable.
good luck.
