Question about Kenwood KDC-MP532U
I have been reading all the posts about the kenwood dash radios heating up a set of resistors causing the display to quit iluminating. I was hoping to get calrification on the exact model. I have a KDC-MP532U with a blank display.
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.

After months of using cleaners and asking techs at shops around the city, and then online, in order to try and fix my display; then I found this site. I figured it couldn't be this easy as boat116 says it is but tried it anyway as I was going to buy a new deck.
My soldering skills are horrible and I ended up with nasty gobs everywhere. But it works perfect now, and I'm amazed. Thanks to all on here.

Old post I know but...I just soldered the 5 resistors and it works good as new. Took about 30 minutes from start to finish on taking out the deck, fixing it and putting it back in.

SOURCE: 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,

Hello. Have the same problem. Have just downloaded the Manual in German. It says In Standby Mode use the small joystick up to FM or AM till it says DEMO OFF and then press the small joystick for 2 Seconds. Hope this helps.
