One of the more confusing car stereo problems can be when an amplifier goes into protection mode. One minute it's working and the next minute it's not, ...

If the protect function works and causes hindrance to trouble shoot, cancel the protection function as described below, and it will be possible to enter the self-diagnostic function mode. (The protection functions other than the excess current dtect function will be disabled.)

While pressing the "Tone Control" and "Info" keys, press the "Power" key to turn on the power and keep pressing those 2 keys for 3 seconds longer.

The seld-diagnostic function mode is activated with the protection functions disabled.

In this mode, the "Sleep" segment of the Flourescent Display flashes to indicate that the mode is self-diagnostic function mode with the protection functions disabled.

Caution!!!! Usiong this product with the protection function disabled may cause further damage to your unit, so use special care when using this mode.

i have a kenwood kdc-241 car stereo and it has gone onto protect mode i have done everything it says in the manual and even taken it out of the car just in case it was damp i have tried putting it back in but still is in protect mode can anyone help me please

Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

It's normal for some amps to go into protect for a few seconds when initially powered up. If it remains in protect mode, it may have shorted output transistors. To eliminate other possible causes, read through the following troubleshooting page:

Let me know if you have any other questions.
