    umm....i was driving down the interstate, listening to music, and suddenly my stereo stopped working and went into 'protect' mode. i haven't tried many things to fix it, mostly because i don't have the owner's manual anymore... please help.

    was playing a cd at the end of the disc and went to "PROTECT". WTF!!!!!!!!!

  • freakout895 May 14, 2009

    Mine went into protect mode the other day and the reset button worked fine, but I turned my car on this morning and it was in 'protect' mode again. Reset didn't work so I'm not sure what to do.

FYI the reset button is a small recessed button, second from the left on the face of the kenwood 6019 and 7100 (the two units I have). You can use a pen or pencil to push it.

If it goes into protect mode. U can hit the reset button located on the front of the face. But according to the manual if this continues to happen, then u may have a short in the speaker wires touching to ground. So i checked all of my wires and connections and it still goes into protect after about 20 or 30 min. of play time at a fairly high volume. I dont understand why unless it is just a flaw in the design. anyone have any ideas?

Selling Receiver

Hello alleycat121,

The KDC-MP235 was replaced with the KDC-MP238 which was replaced with the KDC-MP242, the current model. It's an entry-level receiver that retails new for around $120 with online prices around $75-100.

If the receiver is in good working condition, and you have all of the paperwork and installation accessories, it should be worth about 50% of new cost.

Hope this helps.

Protect:- The speaker wire has a short circuit, or touches the chassis of the vehicle, then the Protect function is activated. Wire or insulate the cable properly and then press the reset button. If the "Protect" code does not disappear, consult your nearest service centre.
