Protect error how do you remove a "PROTECT" error on a Sharp CD-BA2100 stereo?

Take the 4 screws out of the top, lift the CD drawer out, disconnect the two wire harnesses, take the top off, lift the 3 disc tray out, then force the drawer open and closed a few times until it slides freely. Put it back together and it may or may not work. Worked for me.

Here is a solution to a similar problem and it might be relevant: http://www.fixya.com/support/t2327524-protect_error_model_cd_ba200_sharp

Make sure the speaker wires aren't shorted together and that they are not freyed or cracked...the unit is in protect due to it's internal circuitry sensing a shorted output condition...this is in place to protect the unit should the speaker wires become shorted together. You can remove the speaker wires entirely and then turn on the unit to see if it comes on...if so then I would look at each wire carefully to make sure they look good..of course if the unit comes on and the wires look good then you may have a bad speaker component...Now, if the unit stays in protect after you unplug the speakers, then the unit probably has a blown audio output stage inside the circuitry and will need to be serviced.

This is a circuit inside the unit that is proventing the flow of eletricty to the rest of the unit so the amp does not blow. without looking at the unit I could not tell you what blew or what part is effected by the protection fault. However any tv sterio repair shop would be able to look at this and let you know if its worth the fix or not.

1 suspect speaker defect
2. suspect wiring defect ensure all your wires are connected up properly and your speaker are in good order
3. suspect that the cooler fan may be blocked and the system is overheating. use vacuum cleaner on air vents to remove dust.
4 see specialist as this product maybe defective.

If you are a technician desolder the Audio amplifier IC,and check if the stereo turn on but with no sound.If the stereo turn on the audio amplifier IC is in short circuit and need to be replaced.
Good luck

I own a Sharp DVD Micro System XL=DV60 that began to have a "protect" error message when I crank up the volume. Not sure if this applies to your system, but it could be worth a try. Before you proceed, the solution requires you to open up your system (Do not proceed if the unit is still under warranty :)).  
IF you are not experienced in opening up electronic equipment, I suggest you find somebody who does. The error on my system was caused by the cooling fan being stuck or not able to spin. The system has a sensor or sense circuitry wherein, when it detects that the "amplifier" IC heats up, it spins up the fan to cool it down. IF the system detects that the fan is not spinning during the cooling phase, it will give out the "protect" message. Note that the fan only spins when you crank up the volume. Less or 0 volume will shut down the fan due to it's "energy star" feature. One possible reason why using headphones does not show the error, since headphones require less energy that the main speakers, thus the amplifier IC does not overheat. To solve the problem, I cleaned out the dust in the system via a 1 inch wide paint brush (haven't tried the compressed bottled air used to clean computers BUT it might do) and nudged the fan. Played the system w/o a cover and observed the fan operation and so far it has solved the issue. I plan to lubricate the fan shaft with very small amount(less than a drop) of machine oil using a syringe. If it does not work, I plan to see if I could purchase a replacement motor for the fan...
Again, I have not seen the internal layout of CD-BA2100 and not sure if there is a cooling fan. But then again, it's better than having the "protect" error popping up. :) hope this helps....

You have a blown amplifier IC in the stereo that must be replaced, that is what causes the protect error on the display. It is a good idea to take it to a repair center and have them do it if you are willing to spend about $125 to $150, depending on the rates of the shop, to have it repaired. Otherwise, you will just need to get a new one. There is no other way to fix this problem without replacing the amp IC.

Sorry for the bad news, I wish I could have given you an easy fix, but there just isn't one for this problem.

Let me know if I can be any more help.

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.

that is your movement protection. In your manual it says how to get rid of it. mostelikely you have to push power and open button at same time
