Got in car this morning and radio was blinking protect

Hi.

Protect mode is a special condition that kicks in when an internal fault has been detected. In protect mode all the unit function are disabled to prevent the stereo getting more damage in consequence of the fault. The state is a forced standby condition that starts when a wrong voltage or a short is detected.

Try disconnecting the battery terminal, pulling the radio out of the dash and checking the wiring at the back of the stereo. Most of the time protect mode is triggered by a wiring contact. If possible check also speaker wiring. A contact in wiring to speakers will trigger protect.

Regards.

Volume to about between 40 and 28 causes receiver to turn off

It sounds like protect circuit is kicking in due to excessive current. If an OHM meter is handy, check for shorts on your speakers. If not disconnect one speaker at a time from the back of the reciever. Play unit at the volume that it fails. If it then plays fine you've isolated the bad speaker.

My Stereo Is Always On Protect Can It Be Easily Fixed

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.

Subwoofer does not kick in during stereo mode with front speakers

There should be an adjustment in setup that for 2 channel sources, you may have to enable the subwoofer output. Or alternatively, if the subwoofer output for 2 channel sources is in fact enabled, then increase the crossover frequency for the sub.

See add details

Since the receiver eventually works, the delay circuit is failing. This is a circuit that allows the power supply to settle down before kicking in the output relay. This prevents the "pop" that was sometimes heard on older units. This should be a simple and inexpensive repair probably requiring the replacement of a couple of small capacitors in that delay/protection circuit.

Turns off if sound level is increased

there is a protection circuit kicking in.

First thing to check.....Verifiy that all speaker lines are in correct polarity.

+ and gold or writing/stripe on cable.

Check this all the way around and if the sub is a line in sub,, check that also.

You really should just unplug them all and start one by one.

If you cannot get to the wires or its too hard to access,

hold your hand 1/8 of an inch from the woofers. they should be kicking out, not pulling in.

Could also be a blown woofer somewhere in the system.


Hope that helps!

Kenwood amp kac-x401m

How long will the bass play before the amp kicks into protection mode and how loud are you listening to it? I've noticed with my amps that if they don't have enough air flow they will get hot and kick into protection mode. They will also kick into protection mode if you are running it at more than it can handle. Check your adjustments on both your amp and the head unit. Make sure you are not running more bass than the amp can handle.

I have a sa-gx770 techniques stereo reciever, have had it for many years. But the problem with it is, once you start playing music ( a CD) periodically it will shut off through out the song, and never...

There are bad solder connections inside the receiver that are causing the protection circuit to kick in. This is a simple resoldering job and should only cost the labor rate at a local service shop.
