Re: Unit turns on, then clicks off with a "protect"...

You have a bad speaker on this unit or the audio output circuit is in need of repair. Try to disconnect all of the speakers and then turn on the unit. If it still stays in protect, you will need to have this unit serviced, unless you understand how these solid state circuits work. If the unit does come on without the speakers, turn off the unit and add one speaker at a time until the unit will not turn on. Disconnect that speaker and have it checked out or have the wiring checked out. Good Luck

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.

Jvc protect

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Email i got from Sharp:

I do apologize for the problems you are having with your audio unit. The protect mode
indicator will appear when the unit detects abnormal resistance in your speaker setup. I
recommend removing any additional speaker wire that may be added to the unit to extend the
factory speaker lengths. Also, make sure you have all the factory speakers attached, and all
non-factory speakers removed. Finally, please unplug you unit from he wall for 1 hour after
checking all of the above suggestions to completely reset your unit.
If you are still having issues after doing all of the steps mentioned above, the unit may need
to be evaluated by a Sharp Authorized repair center.

Sharp Stereo- Protect Mode??

Try plugging in a pair of headphones. I tried it without the speakers connected and since it found the headphones and they were OK the system came out of protect mode.

Problem with turning my system on....

whan a unit goes into protect, it could be a bad speaker, shorted speaker wires. or the most common fault is a blown audio o/p ic in the unit. due to being compact units they are more difficult to work on than the full size unit. the part typically runs between $25.00 to $75.00 usd. if you are good with working on small places and are good with soldering give it a try. the ic will be on a heatsink. good luck.
