SOURCE: I have sharp cd pc3500

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.

Will not play , loud clicking noise. No lights nothing.

Ther clicking is probably coming from a relay and it is cycling because either the power supply itself or possibly an audio output power module has failed, the latter will overload the power supply so it tries to protect itself by interrupting either the AC or a DC voltage supplied by it.
This problem will likely require the hands-on of technical help.

Unresponsive buttons

First, try unplugging the unit for a couple of hours. That should reset the internal microprocessor. If that fails, try pushing all of the buttons one at a time. If one of them is stuck, nothing will work properly. You should be able to feel the button working. Report back here with your results.

Won't start up

"Protect" error could mean one or both of the output IC's are defective. This can be caused if the speakers or the wiring have shorted. Try the unit without the speakers to see if it starts up.
