SOURCE: Pioneer car stereo output Ic's

In most cases the problem is the electronic volume IC, ref # IC151 and part number PLM003AM (in the DEH-1600). It is a different part number and ref # in other models.

It is not always this part that causes the failure, sometimes it can be the muting transistor, a voltage regulator or even the micro on more rare occasions. It will require some troubleshooting to figure out exactly what part it needs. You will need to have an O-scope to trace down the audio signal and follow it from one pin to another. You also need a multimeter to check a few voltages in the radio. All of this must be done on a test bench with the radio powered on with a power supply. If you do not have these tools, you will not be able to figure it out for certain, you would only be taking a stab in the dark. That can get rather frustrating and even expensive buying parts that do not fix the problem.

The electronic volume IC is a flat pack surface mounted component and requires the very best soldering skills to be able to replace. It is very easy to do damage to the circuit board that can not be repaired if it is not done perfectly. If you have not replaced these type of components before, you should not even attempt this repair.

If you would like the service manual I can sell you the PDF format of it for $10. I also have the service manuals for most Pioneer products as well as Kenwoods, JVC, Panasonic, Denon, Marantz, Clarion, and more. Let me know if you would like to get it. The service manual is very helpful in repairing electronics. It contains the schematics and parts list which is vital to make sure you get the right parts and to be able to trace down any signals and to know what parts are doing wha, and to figuring out if the voltages are correct.

I hope this helps,

Dave

SOURCE: i need unlock code for my kdc-mp2035 kenwood stereo

Unfortunately Kenwood codes are only available from the Main Dealer or by using a Radio Decoding Service who will connect a laptop to read the working code inside your radio`s memory chip (EEPROM)

My stereo have a problem when i am opening it the screen appear protect how an i solve ghe problem of that stereo


First, if you can, check your speakers and speaker wires for shorts and/or grounds. If they check out fine, press the reset switch, it should be a small indentation about the size of a pencil tip and will not be marked. If that doesn't work, you may have a bad output ic.

Not really.It probably fried the either IC board or IVR.It would be much cheaper to buy another one and pay professional to install it.

On my kenwood kdc mp438u i tried everything it said to do but it keep saying protect


Could be a short circuit on your speaker output, try disconnecting all 4 speaker wires and then power up. Otherwise its the audio amplifier circuit that needs to be replaced ( audio IC )

Static in speakers when treb in turned up and volume above 50%


the output ic is cooked. it is upc1130h2 or similar.
these chips are floating ground.do not ground one speaker lead.
outputs are typically 7 dollars.
it is mounted to the aluminum heatsink inside.you need to desolder and resolder the pins,and then solder in the new one.
special heat sink compound has to be applied,or it will go very quick
