Question about Kenwood KDC-MP2035 CD Player

1 Answer

No sound I've just installed an MP2035 and there is no sound. I've triple checked the wiring and all fuses. The unit lights up, but there's no sound for the tuner, CD or auxilary. I have installed a number of radios over the years, so this isn't a first timer - but I'm wondering if I'm missing something with the internal "computer" set up with the unit. Suggestions?

When there is no sound from an car audio in-dash receiver, FIRST be sure that all connections are GOOD!!!. Incorrect DC conditions affect many units by muting the audio output., so check ... a mistake (often a short circuit or short to chassis in the speaker wiring in a power up condition) has often been made at the deinstall or install under way stage, in that a in a bad condition may result a “no go” situation, that can blow the units audio output IC(s).
Most high power BTL output stages present in a particular way. This can help us to identify a problem with the operation of the device. Whilst the unit is still in the car, measure the voltage on each of the speaker outputs with a multimeter. If they do not appear to be at approx 6-8 volts range, then the output chip(the chip with a heat sink tab secured by 2 screws about *----------* far apart), may have blown. Open the unit up and you can often see this "blown" chip often as

  1. cracks in the black plastic part of the chip
  2. burning or "melt" stains on the PCB about the pins of the output chip.
  3. pins from the chip completely missing or "fused"
  4. main power supply fuse blowing
  5. burnt copper tracks to the printed circuit board about the audio output chip
  6. SMOKE coming out of unit is often a giveaway.
If the chip "looks" blown... then it will be. Replace it with a new one and see how you go. Always check for shorts and short to earth in the speaker wiring before reinstalling unit as reinstall of a unit that has been fixed can be completely undone by the same short circuit still being there.
NOTE-----NOTE-----NOTE-----This is an expert type repair to remove an output chip form a modern in-dash unit. A lot of energy(power) is focused in this area, and mistakes made.... usually result in more "blown" replacement parts. If you have NOT done this type of repair work before, GET A CAR AUDIO DOOOD to give you a quote for the repair. It is better for him to do the job for you, then you get a warranty also. Just remember that some output chips can be as much as $80 to replace, so experts attention is needed to find and restore a faulty part replacement at this level. Be sure to use the EXACT replacement part from the OEM(original equipment manufacturer) right down to the brand of chip WHERE YOU CAN to avoid any extra complications from the part being incorrectly spec'd for the job and still not working when you install it.

Double check the red..yellow and ground wires..sounds like your not getting power.. check fuse in unit itself.. when installing any component in a vehicle..triple check and use things like solder and shrink wrap..always remove negative cable from vehicle battery prior to starting work or adjustments .also prior to removing cable from battery..reference owners manual.. some vehicles need to be disconnected a certain way to avoid future electrical and drivability problems..also ensure faceplate is secure

When head unit is on tuner everything is fine when on ipod or cd mode there is no sound ...i have taken off the face and reset the unit and still tuner sound on ipod and cd sound off

are you using an amplifer? if so, it sounds like you are using the blue wire instead of the blue/white wire to turn the amp on. the blue is antenna remote and turns of when it is not in tuner mode. the blue/white is amplifier remote.

This is a safety feature to avoid damage to internal components, the wiring must be shorting out to earth. Disconnect the speaker cable connector at the rear of the unit and try it, if it is ok then you have a speaker wire shorting out to ground. if it is still saying protect then disconnect the other wires one by one.

I can't figure out how to get the player into mp3 mode. There is the button that changes between CD and tuner, but that doesn't do it.

Here's what they don't tell you: AUX isn't automatically an option when you scroll through the SRC button. You have to turn it on. I know, I know...stupid. I had to contact Kenwood (the maker of the unit) directly to get an answer.
  • First, press the SRC button repeatedly until it displays STANDBY.
  • Then hold down the Menu button until MENU is displayed.
  • Next press up or down on the right control knob, to scroll up or down, until AUX OFF is displayed.
  • Next hold the right control knob to the left or right until Aux switches on.
  • Now just press the Menu button to exit.
  • AUX will now be an option when you scroll through the SRC button

Mp2035 cd player will not turn on.

My hunch is that the fuses blew. When you cut all three at once you shorted the battery to ground and most likely blew out the fuses. Check the fuses and let me know. That is my best guess. Good luck

Not Holding the Memory

Sounds like a wiring problem.

There is a YELLOW wire that should be connected to a constant +12 volt supply when the vehicle is off. This retains the settings.

Check the connections and see if thats the problem.
