Question about Kenwood KDC-X590 CD Player

Re: Repair response

Hey there. Thanks for taking the time to post your knowledge...very cool to have people that care!

I do have a little experience soldering but how delicate is this procedure? Also, I'm not sure what you mean by the main board but I'm assuming you're talking aobut opening up the unit (as opposed to the face plate) & pulling the board out of that?

Do you have any kind of reference like a picture or diagram of what I should be looking at? If so, please feel free to email me at y2kasper2002@yahoo.com.


Thanks again!

Randy

If you are talking about the problem with the display out, yes the main board is right under the cd mech. All you need to take out is the cd mech, not the board if you are wanting the reflow the solder on the surface mount resistors in the front right side (with the radio facing you).

If you are talking about something else, just let me know. This question was not addressed to anybody specifically. But this is a comon problem with this model. I just came across this question today.

To ask a specific person a question you need to click the "Ask me" link right below that experts name.

If this was not eant for me, I am sorry, but I thought maybe it was.

Hey, everytime i try to play a cd it says error...is my cd player broken or is it something i can do to fix the problem?


Hi jmatt313,
If you have necessary tools and test instruments, know safety precaution in basic troubleshooting try the steps below to solve your problem.
Assuming that the disc is good.
1.Clean the lens. - Sometimes because of dust and any fine foreign objects build up at the top of the optical lens it can't read any disc. Try clean the lens by soft cotton buds. Be careful while doing this.
2.Check the ribbon - Check the ribbon connected to the lens from the main board for scratch, damage. Once it has an open line then of course the lens can't read the disc. Also try to erase the contact by pencil eraser. If you've done the steps above and the symptoms still there then the next step requires you a little knowledge in soldering technique and reading the ohmmeter.
3.Check the motor - Check the motor that spin the disc with an ohmmeter. You can test it using the ohmmeter (x1) even it is connected on the lens assembly.Good motor - reading should be fairly high and it will spin. Bad motor- reading will drop to low resistance and will not spin.
Hint : 50% of my repaired unit the above parts are commonly caused of the problem.
If you confirmed that you have a defective motor then replace it with a new one. Before replacing the new motor you have to check the clearance of the disc holder with the old one. The clearance should be the same as the old because if not the lens will not read the disc if it is too far or too close.
If the above steps didn't cure the problem, high chance that your optical lens was faulty.

If you can't do the job yourself, I would advice you to look for a professional to troubleshoot the symptom.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

I cannot adjust the stations, switch to CD or Radio mode or anything as it's stuck on one XM station. The presets won't even change the station. I noticed the disp/title button seems to be sort of stuck...


Hi,
Yes, Disp/Title stuck button could be cause of no other button function because one button can be operated at one time in these units and if any button stuck for some reason, other buttons would be inoperative.
Take off front panel by pressing eject button at lower left side and try to release Disp/Title button with finger nail, if that does not help then remove screws at back of front panel, take off back cover then take out circuit board carefully and press gently, little bit Disp/Title knob from inside front panel to send it back in its original position then put circuit board and put back cover and tight screws.
Check Disp/ Title button gives little click sound while pressing as other buttons give that sound. Put front panel in unit and check.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

Wired it wrong and there was a little smoke from the stereo system. now it doesnt work. Anything i can do about it??


Smoke coming from electronics is never a good thing. If it was working or new before you wired it wrong, chances are it isn't something you could fix without the knowledge and proper test equipment to pinpoint what was fried. There are no user serviceable parts inside the unit. You can send it out for repair or get another one.

Kenwood deck cd eject problem


Actually, yes! That could very well damage any unit without a protection mode. Unfortunately, in my long time experience in car audio, a deck that spits cd's out has a damaged or misaligned laser lens. This could be caused by driving to fast through pot holes, speedbumps, or going down train tracks. Find an electronics repair shop locally to see if having it repaired will out weigh a new deck. I found one new in box on ebay for $89 + shipping.

CD player issues


Burned Cd's do play in these, I use them all the time when I test the one's I repair.

Yes, it is the "SCR" button you press, it stands for "source".

Since it is in your boat, it could have a small amount of water damage in it. I have seen some strange problems with car stereos put in boats.

The problem you are describing is nothing that any normal end user can fix, meaning that there is no reset that will help or anything of that nature.

If you are good at taking things apart and putting them back together and able to pay close attention to detail, you may be able to fix this yourself if the problem is not too extensive.

If it has a small amount of water damage, you could clean the main board and see if that helps.

First you take the top off, it has 1 screw on the top right in the back middle of the stereo. Take it out and then take the top off carefully so you don't bend it up removing it. You need to gently pry the sides up near the back first, then a little closer to the front as well. After the top comes off, the CD mech has only 2 screws holding it in, they are at the front of the mech at the bottom and connect into a brass post. Take them out and the mech will come out very easy, but be carefull not to damage the ribbon cable holding it in. That ribbon cable can be taken out right at the main board where it is connected. Just pull it out of the connecter, nothing special holding it in, just a tight fit.

Now you can see the main board. First remove the plastic part that holds the display, it has connectors that just need to be lifted a little to pull it off.

This may be all that needs to come off, but taking the board out all the way may be whats needed, so go ahead and remove the screw that holds the board onto the chassis. Might be just 1, maybe two. Look in the middle front of the baord for a screw and the back area also. You can always look at the bottom of the chassis to see where there are screws coming thru and remove those. Now on the sides of the chassis are screws on each side near the back to remove. After you get those, it should just pull out with the heat sink attached. Just make sure you don't force anything out, it could break the board if you missed anything. I am pretty sure that is all, but I am going off of memory and might have forgot something.

Once the board is out look it over very closely for any type of green or greyish type of corrosion. Check the pins of the IC's with a magnifier if need be. Any tiny little spot of corrosion can cause problems, even if it is not on a component.

The solder should be shiny and silver, no rings or cracks. If any of them are grainy looking they may be bad also and would need to be reflowed with a soldering iron and a touch of fresh solder.

Any of the corrosion you may find can be cleaned with an old toothbrush and some alcohol. We use flux remover in our shop, but it's unlikely you have any of that. After cleaning it off with alcohol it will leave a residue that does not look good, but don't worry about that. It won't do any harm. Just make sure all of the corrosion has been removed. Look at every little area of the board on both sides.

Once it is done, just put it all back together just the way it was taken apart. Don't forget any screws and make sure they are on tight but not so tight it may break the screw. Just good and firm.

After doing this, if it still does not work, you will need to take it in for service or just buy a new one, these models are just a little over $100 and the repair will run close to that much or more.

I hope you found this useful, if so a FixYa rating would be appreciated.

Thanks and good luck,

Dave

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.

Problem with my kdc-4019


The most likely problem is the laser pick-up, it needs to be replaced. There are also a couple of other things that can cause this, but all of them are things that only a service technician can figure out. Things like the spindle motor, the DSP IC, or a defective voltage regulator. None of which are easy to diagnose without the proper test equipment, service manual with schematics and knowledge of how to troubleshoot electronics. I work at an authorized Kenwood service center and have over 18 years of experience repairing them myself, so I am not just guessing at this.

When the laser pick-up goes bad, it cannot read the disc. The very first part of the disc that it tries to read is the TOC, which stands for the "Table of Contents". If the player can not read that area of the disc, it cannot play any of the disc. That is where all the information about the disc is located. You can ask any technician who repairs CD players and they can verify what I have posted. Call a service center and ask to speak with a technician for a moment.

Most repair centers charge about $125 to $150 for this repair, depending on the labor rates of the shop and the mark-up of the part. The laser pick-up is the most expensive part of the whole radio normally.

I would be happy to offer you more help if needed. If you need a part number or even the service manual, I can email that to you (I have it in PDF format) if you have some electronics knowledge and want to do this yourself.

I hope this has helped you, and if so, a rating of "FixYa!" would be appropriate and very much appreciated. After all, it is the only reward we get for offering free help to people like yourself.

$250 is a bit tough if you are sure the IC is only $27. It is not clear from your post if your microprocessor works alright. If your display and other functions were okay when you gave it to the service guys, your micro is okay, in that case the only other costly thing in your board is output ic. Getting a board from Pioneer isn't easy, they don't sell boards in shops, they provide it to their authorized service ceneters only. You can try finding a friend who is aware of the boards and have this checked.
