Protect comes on why


Hello
Protection display will come over this type of set, when it is overloaded or system confused condition. Just unplug the device from AC mains socket and replug it after 4 to 5 minutes, and see whether it shows any protect display. If it shows it again, just disconnect the output loads, ie, connected speakers, and check. Again it displays 'protect', the internal circuit, especially the output amplifier circuits has the trouble, and the system need service. if it does not show protect display, after disconnecting the speakers from it, check the speakers or its connecting wires for damage. OK.

My Sharp CD-M10000W displays "PROTECTION"


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

I have sharp cd pc3500 stereo system when i turn the power on the message on the screen shows PROTECT. I cant do anything nor any function work


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.

My sharp cd BA150 is in Protect mode. What can I do?


The protect mode indicates that a problem was detected in the final stage of amplification and the unit has shutdown to prevent further damage. These units use an AMP-pac part number: VHISTK40270N1 which is available at tritronicsinc.com for $53.09 plus shipping.

Most likely cause could be a blown power amp IC.
