That is a DC error.

What happened and why?
amp IC is fried, probably from overheating playing at very loud level. Maybe from a speaker going bad, maybe just random part failure

Is this fixable?
Yes

How do i fix it?
You must get the replacement part, take the radio apart, remove the solder from the amp ic, put new IC in and resolder connections. Put radio back together without forgetting anything you took apart. Also need to make sure the soldering is good, no solder bridges or anything like that (you wouldn't want to blow it up again right after replacing it)

How do i prevent this from happening again?
If it was caused by playing too loud for too long, don't turn volume up to point of hearning any distortion, that is clipping in the amp you hear and is very ******* amplifier ic.
If it happened from a speaker going bad you must replace the bad speaker.
If it was a random part failure there is not much you can do, you had some bad luck, thats all.

If you do not know how to remove solder and to solder very good, it is reccomended that you take it in for service, but it may not be worth it since this unit is not very exspensive. A shop may charge as much as $100 for this repair. part alone is about $30 or $40.

If you want to know the part number please reply and I will look it up for you, or you can get the generic number off the ic itself.

Make sure that the music files are indeed mp3 format. An iPod will play several different formats but most av head units only play mp3. A lot of the songs that are downloaded from iTunes are actually mp4

Volume decreases drasticly after playing loud 15-20minutes


Shes overheating and thus goes into emergency mode and shuts down the volume to help cool down the built in amp . Dont know if it has a built in fan (likely not) but its overheating which can be a number of reasons why...from a failed heatsink componet, inadequet venting, shorted circuit. Can you take it out and inspect it?

Firstcheck whether it is still in demo mode. to cancel demo mode -- press [enter]when message flashes "to cancel DEMO mode press ENTER key" for 10-15 secs. Turn the control knob to "YES" and press ENTER key. If it still fails to operate properly press the rest button to return to factory settings(The reset button is behind the front console)

Error message on screen will not go away


Hello bigdsketch,

The "DCER" error is caused by one of the speaker wires shorted or grounded or a shorted voice coil. Remove the speaker wiring one at a time to determine which one is causing the error, then repair or replace the defective part.

You may need to press the reset button (small recessed button to the lower right of the volume control) after the problem is corrected.

Hope this helps.

Kenwood KDC-138 Operation Problem


Here's the quote from the manual regarding "dcer": "The speaker wire has a short-circuit or touches the chassis of the vehicle and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT/DCER" code does not disappear, consult your nearest service center "

I believe the manual can be downloaded from crutchfield .com after you go to the Kenwood KDC-138 page on their website. The reset button is either on the lower left of the face or, removing the face, on the lower left of the body. Hope this helps you.
