Question about Kenwood KDC-X590 CD Player
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 email@example.com.
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.

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

Tips for a great answer:
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!
