There are a series of them in the right front corner (as you look at it from the front) of the main circuit board, on the top side of the board. You need to take the top panel off the radio and then remove the CD deck. Be careful removing the CD deck, it has a ribbon cable connecting it to the main board, you can just move the CD deck off to the left back side without disconnecting the ribbon cable if you want. The CD deck is held in by 4 screws, one in each corner of the CD deck at the bottom of the deck. They screw into some brass stand-offs from the bottomo of the radio casing. The surface mounted resistors all have "2R7" on them, and all of them need the solder to be reflowed. Just a small touch of the soldering iron and a very small amount of solder on each side of each resistor. This will get the display working again 99% of the time with this problem for your model number. It is always possible that there is a different reason for the display going out, but for your model number, this is a very common problem.

A "FixYa!" rating would be appropriate and very much appreciated for this free information. After all, it is the only reward that the "Experts" here at FixYa! receive for helping people like yourself. I hope you have a good day, and if you need any further help with your radio, feel free to just reply to the post with any further questions.

My kenwood KDC-X590 car stereo has no illumination but radio and cd player works. Is something burned out? HELP!!


there are about 8 - 10 surface mount resistors inside of the deck that need to be resoldered. They are on the front right of the board with the face toward you.

Display screen not working


Sounds like you might have a bad connection where the faceplate connects to the unit, or the faceplate is bad.

Similar problem, does anyone have pictures?


what are you trying to fix on this deck? if it is no illumination, there are a series of surface mount resistors on the right side of the deck as it is facing you. you need to resolder these resistors.

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.

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

Hey did u find the curcut # on the kenwood kdc-x590 if so pleas let us know !!! thanks for ur time


Are you talking about the circuit that lights the display? If so, you need to resolder the surface mount resistors in the front right corner on the top of the board. Front right while facing unit with top off and CD deck out. you will see a series of surface mount resistors and they all are connected in series. All of them need to be resoldered. That will make the display work again.
