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.
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.
Hi, This feature is designed to protect the unit from short circuits going to the speakers. To test this, 1 Shut off the System 2 Disconnect the speakers from the back of the system. 3 Start the system with the volume turned completely down to 0. 4 If the system starts and does not go into protect. Do the following
a Turn off the system b Check the wiring to each speaker and make sure none of the wires or wire strands are touching each other. Do this at the speaker end of the speaker wire and at the system end of the wire c Connect the speakers back up observing not to have any strands of the wire touching each other d Turn the power on and see if it plays OK. e If it does not power up properly. Leave the system completely off for 45 minutes. Then turn it back on and see if it works properly. If it does not at this point. Professional repair will be necessary. Hope this helps, Best, Mark
Disconnect the speakers and turn it back on. If it still says "protect" it needs serviced. If not, turn it off and re connect one speaker at a time and turn on. If it goes back into protect, you need to check the speakers themselves for an internal short or a blown voice coil. If you have a multimeter, check the impedance on the speakers or the resistance on the speakers. If the meter reads 1...... the speaker is more than likely bad. If you need further help, post a comment and I can help you further.
Stereo sytems have a protection circuit that alerts you by displaying "protect" when there is a electrical short circuit detected in the system, the most common short happens in a speaker, try disconnectig the speaker wires of both speakers(all speakers) at the back of the system, then play the CD or cassette player(although you will not hear anything with the speakers disconnected) and see if the unit goes into "protect" mode if the problem is still present then you have an internal short circuit and the system will need to be sent in for service or replaced(depending on age,repair costs). I would not recommend investing more than $80 into repairs. Now, if the unit does not go into "protect mode" then one of the speakers or speaker wires is shorted,be sure you check the conndition of the speaker wires before you replace the speakers, then you can replace the speakers(in a pair) and you should be back up and listening! Good luck and Merry Christmas !
You cannot . This a feature that detects a short and shuts the stereo off before it can do further damage. If you can disconnect your speakers try that then turn on your stereo. If it displays protect mode your problem is internal. If it stays on try hooking up one speaker at a time to see if one of your speaker is bad. Make sure you turn off your stereo before attempting to reconnect your speakers . Good luck
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
