Question about Kenwood KDC-X590 CD Player
What a wonderful thing to see posted, when I saw your solution. I have opened my headunit in the past suspecting the problem was internal. Do you know if the KDC-MP532U is basically the same in regards to the bad solder joints?
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,

Thanks tech48! I had the same problem, fixed it today on my kdc-mp532u. As you described, I just had to resolder the five resistors on the front right of the headunit (not the faceplate/display part). There are five surface-mount resistors connected in series, each resistor 2.7kOhms in value. You can use an ohmeter in the two vias that the resistor-network is connected to, and make sure it adds up to about 14kOhms.
