Dear petfresh,
Please switch off the system, remove the speakers wires from the system and switch on the system. If system gets on then the speakers or speaker wires are defective.
Output IC is Audio out put IC.( Integrated circuit)
It can be fixed only by service technician at service point

SHARP BA200 Protect Mode?


Check the speaker wires for shorts, if okay! the audio output ic's are loading the circuits causing the protect mode to engauge, only option replacement of the above mentioned parts.

What does it mean when it says protect when power on?


It indicates that the audio output ic is shorted, first check the speaker wires are not shorted, if okay! the audio output ic must be changed to fix the problem.

It's not coming out of stand-by mode.display shows only stand by mode. non of its function is working.


It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition.ALSO if there is no action the processor should be checked for the parameters.

The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

I just got a jvc compact component system hx-d7 i go to turn it on and it turns on but thats about it i get a red light at the on button and it beeps could it be a fuse on something


This seems that the unit switches off due to a protect cut off. It is not so easy to probe into to find a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier.

My stereo won't work. Whenever I try to turn it on, it always turns off saying "protect." How can I fix this?


The protect has come on because it senses an output load problem, Turn the unit off, unhook the speakers and wires from the stereo, now turn the unit on and turn the volume down as far as it will go, this should reset the processor ic, if the word protect stays off you have a short in the wiring or bad speaker. If the protect comes back on with everything unhooked the problem is in the audio output ic pack in the stereo and will require a technician to remedy.

My audio system says protect on display


As Shown Here, A Sharp-Associated Repair Person Suggested Replacing A Specific Output IC, As Well As Two Other Small Components. The Total Of The Three Replacement Parts Is $55.43. I Suggest Doing The Repair Yourself, As The Stereo Would Be No Longer In Warranty, Unless You Have No Experience With Working With Electronics. You Could Also Get The Repair Done By Circuit City, Best Buy, Or A Similar Electronc Consulting Business

Protect error


The 'Protect' error means there is a DC voltage present in the output section(which should not be there). This can be caused by a defective output IC(the big IC on the heatsink). Disconnect the IC and see if the error goes away.Also check the resistors around the IC.
