Hi Jean,

Without a brand and a model, best that I can provide are generic possibilities:
1. unplug the unit from the mains for a couple of hours. This is supposedly to reset most systems; and/or
2. check the speaker wires and make sure none of any bare wires are touching each other.

If your concern has not been corrected after completion of the above procedures, pls post back brand and model.

Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Hi again Jean,

    Understand now that your concern is a Sharp BA-1700. The message "PROTECT" indicates that the built-in diagnostics have determined an internal fault which could either be:
    1. the logic circuitry or the firmware controlling it;
    2. amplifier circuitry or its components;
    3. mechanical problem.

    Of the above, I tend to suspect the audio amplifier section to be at fault. Normally this would be a single power pack IC that provides audio amplification to drive your speakers. They often fail when driven loud.

    If you have done any or both of the two procedures initially posted and no positive results, am afraid that your only alternative is to seek the services of a qualified professional since this would require opening the unit. Further diagnosis and appropriate repairs would require that you be familiar with electronic circuitry and components, use of a DVM and a soldering iron.

The display just reads "protect"


Protect is bad. It means the amplifier thinks it is overloaded. Check the speaker wires to make sure there are no loose connections or shorts.

My Sharp model no. CD-BA250 is displaying "protect". It will not turn off on or anything!! How do i clear it out to fix the problem.


Disconnect your speaker boxes. If the "protect" error goes, then the speakers or wires may be at fault. If the error remains, most likely the audio output IC is blown.

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
