Re: LCD Screen Out?
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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

I also created a tutorial on fixing faceplates with 2R7 resistors (refer to my tip).
But, your unit will have a different chassis, as the faceplate is also a video display.
First you need to determine if the buttons on the faceplate are operating the various functions. If the buttons are NOT operating, then the faceplate itself (or connection to the main unit) can be considered faulty.
It's highly probable that the RIBBON cable (which connects faceplate to the inside of the unit) may be defective - this is common in some Kenwood units.
Try searching Google or youtube for ribbon cable repairs etc.
This is an indication of mechanical malfunction. Most of this symptoms is due to dirt build up inside which caused the mechanical to stuck. The unit must take apart to clean the tray and make an air blow. Another reasons of symptoms is the faulty mechanical tray motor. Once this part is faulty the tray will not eject and will sense by the processor and trigger the error code.
If you can't troubleshoot the unit yourself, I would advice you to look for a professional to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
The laser or laser mech or both are worn out. This is a very common problem. I had to replace my laser mech in mine. My advice is to replace the laser and mech. Best website for great prices and cheap shipping is..
You can find out how to take your ps3 apart and to show you how to replace the laser mech on youtube. You will need to take it apart before you order the new part. There are 2 different laser mechs... The model code in one the laser mech its self. It will be Kem-410ACA or Kem-400AAA.
One more thing, once you replace the laser mech somtimes the cd holder I guess is what you could call it, its the where the cd sits where the laser is reading the cd with not accept the cd and jam. This is common just make sure every spring is set in the right place. There are also videos on youtube showing what to look for. Everything has to be in sync. It took me like 2 hours the get everything in sync .. But some people have no troubles at all.
Yes, the problem is inside the main unit. I have fixed hundreds of these radios over the years.
The solder on these resistors get heat stressed and stop conducting properly. They just need a tiny little touch of solder.
With the radio in front of you and the face is facing you, take the top off and remove the CD mech. The CD mech can just be set over to the left a little and the ribbon cable to it can stay connected. Just move it out of the way gently. You will see a series of resistors in the right front corner area of the main board on top. They have 2R7 printed on them and there are quiite a few, all in that main area. Just resolder them and put it all back together again and the display will work normal.
this unit needs a new cd mech I have repaired over 100 of this model , RP8075 is another model it uses the same mech part number for the mech is
RCA Part Number: 255908.. if you need help in replacing the mech let me know
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.
I think you have a disc in the mechinism that has popped out of the tray.
Taking these apart and getting the disc out can sometimes be a pretty difficult problem. If you do not have some good mechanical skills and are able to remember exactly where each screw goes and how each cable is plugged in, I would not try it yourself.
A repair center could probably fix this for around $75, depending on the rates of the shop. It should only take them about an hour to do this. And normally they will also clean and lube the mech properly while they are already in there.
If you do attempt this make sure everything goes back together exactly the way it came apart.
Once you get the mech out of the unit, look to see if there is are any disc's that are out of place. Sometimes you can push the disc back into the tray without dis-assembling the top part of the mech. This would be the preferable method so you will not need to re-assemble the mech. If a tray is loaded into the area where the laser pick up is located and a disc is actually clamped into it, do not try to remove that.
It is likely that it is in the proper position.
If you require any further help let me know, and a good rating is always appreciated.
see if the disk tray comes with a rubber belt. if it does then figure it out how to remove and replace it! if it comes with gears then it probably needs maintenance like greasing some part of it causing toomuch friction!. replace the rubber belt if any! rubber belts often loosen especially with much heat build-up
