Question about Kenwood KDC-X590 CD Player
My display on the faceplate has stopped working, is there a battery in this unit or some type of recall or fix for this ?
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.

I did the repair posted by Tech48. Open up the radio, take the cd player portion out, and resolder all of the resistors in the right front portion of the radio ( when looking from the face side) There are a row of around 10 or so of them, with the letters 2R7 on them. Place the solder gun on the joint and it will begin to melt the joint, then flow a tad of new solder onto each joint.
My face is now working after the repair. Thanks again!!

I have the KDC-632U and experienced the "black screen of death" error on my deck. It would occassionally come on and eventually failed altogether. I opened the faceplate and did notice the mark on the LCD...but it's not a factor. I opened the head unit (Thank you Tech48) and found the resistors on the right side. When magnified, you could actually see where the cracks had formed on the solder and there was a break in the circuit. I resoldered these resistors (and some others, for good measure), put it back together, and it works like a charm. THANKS for all the help folks. It's a quick fix, and a great save!

I have the same problem with my faceplate... but the problem isn't actually with the faceplate. I have friend who bought an X590 head unit a month after me, his still works properly. So I swapped our faceplates, and what do you know, my faceplate works fine with his head unit. So the problem is within the head unit itself.

I am going to attempt fixing my X590 soon, but I want to know if anyone
actually took any pictures, or if anyone is kind enough to take theirs
apart to take a few pictures of exactly what and where needs to be
soldered? I have never done this before, but I think I am handy enough
to pull this off. Thank You.

Wow....Thanks alot for the help Tech48. I want to make a donation! I am back in business :)

Would the KDC-MP532U head unit suffer from the same bad solder joints? I have two of these and my wife's just followed mine with a non existant display. I am so glad I saw this post.

Guys, I just wanted to say thanks to Tech48's solution and because of his technical expertise my KDC X590's display is back up and running like it should be. Even though the problem seems as if it would originate from the faceplate itself it isn't. I too took apart my faceplate and looked at it and found the "burnt black spot" that everyone talks about. Again though this isn't the problem. Download the service manual for the X590 and follow Tech48's guide on which resistors to solder here: http://www.fixya.com/support/t689830-kdc_x590 and you are good to go. Thanks Tech48!

The ones that are burnt need a new faceplate assy, for the ones who work sometimes and dont its usually a loose solder connection osmewhere on the board, not the faceplate board but the main board of the unit, im currently working on one now if i find it ill post the curcut # for every1

I have exact same problem with all LED's on my KDC-X590 faceplate do not illuminate anymore but all functionality is OK (all the buttons and functions work). It started as intermitent problem but lately haven't seen the display for months.

I fix it too....
My Kenwood model is DPX-501U (2din)
I resolder the 2R7 resistors at the mainboard and the display works fine again.

I hv a same prob with dpx-4020
but i could not find the resistor..
anyone can help

Brilliant! Thanks everyone for sharing. Same problem here, so this site was perfect! I will post my results after breaking out the solder gun.

Thanks a 1.000.000 tech48! My display cut out whilst on holiday in sunny Italy. Radio controlled blindfolded, with random results.
Soldering the 5 SMT resistors in place did the trick. This is what I love about the internet. Real life issues and ways to resolve them.

Tech48!!!! wOw! I was ready to give up... You ROCK! Instructions were PERFECT! If you ever get to Canyon Lake, Texas, I owe you some beer, scotch, whatever you like. Look me up... www.dgdigitalimaging.com

Just to let you know the burnt out looking portion in the face plate is supposed to be there. It is not actually burnt out. If you follow "tech48" solution you will find that it will fix the problem. I have been driving around for about 5 months not being able to see what station I am on, or what song is playing. Thanks to "tech48" solution I can see in the dark again. : )

Just fixed my KDC-MP532U following tech48 instructions. Works great just be cautious not to overheat the surface mount resistors or they will come off completely.

Tech48's solution is exactly right -- worked perfectly on my mp632u. Once I got the unit open, found the resistors, and didn't see any that were visibly loose, I thought 'there's no way that simply putting a bit of solder on all these ends is going to make any difference', but sure enough -- it did.
one more thing -- if you can't find the resistors (or don't know what a surface mount resistor looks like, as i didn't), there is a diagram here: http://claims.satisfusion.com/ServiceLit/Kenwood/BulletinsAndManuals/KDC-MP632U.PDF

Hi well i just got a 2000 dodge dakota and it hade the kenwood deck in it and the face plate did not work !!! i open the face to see if there was somthing wrong and only saw that there was that burn on it but i open up the hole deck and still could not find the problem !!!! so i put it all back together conetet back in the truck but since i dint realy car about the deck i started hiting the top of it whit a wrich like 3-4 time and it came back on !!!! just hit hard but not to hard and it should come back on!!! am just happy that i dont have to get a new one

I took my faceplate apart and noticed there is a little burned spot on the bottom left hand side of the digital display. My assumption is that some sort of transistor burned out. I don't see how that part could be replaced unless you replace the entire digital display unit. Kenwood should have known better and created a display that would not fizzle out. I love this deck and hate to replace it. I won't buy a Kenwood because their new decks seem to have the same type of digital display.

I just took my faceplate apart... what do you know... a burned out portion on the lower left hand side of the faceplate.

SYMPTOM: No Display.
COUNTERMEASURE: Re-solder the following components on PCB X34-415:
R43, R44, R46, R47, R48, R49, R50, R51, R55, and R57.
Ok so if you remove the top of the unit and cd player down the right side you see a line of surface resistors that say 2R7 on them, they all need to be resolders to the bord theres 9 total.
