The protect message indicates that there is a problem with the output amplifier section. Verify that the speaker wires are not shorted together. If they are fine, there is an internal problem that is usually the output transistors. Your specific model I believe uses an amplifier pac (STK411-230). It should be replaced. It is available from tritronicsinc.com using part number VHISTK4113E-1 at a cost of $83.04.

Radio flashes (protect)cant get any stations at all


This is an indicator of an output load problem, turn unit off! remove the speaker wires from the back of the stereo, now turn power on and turn the volume down. If the word protect stays off there is a short in the wire or one of the speakers, but! if the word protect comes on " with the speakers and wires dis-connected " it indicates a short in the audio output ic pack in the stereo.

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.

You got to open this puppy up and replace the 2 bad IC boards.  Known problem with this brand stereo.  Defect in the IC boards causes your fuses to blow and they will keep blowing every time you try to put new ones in.  Cost for parts will be about $200.

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.

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.

Can't do anything - LCD screen says "PROTECT"


It may be that there is a problem with a fuse inside the stereo. It may say protect because the fuse has broken a connection that allows it to turn on. If the protect goe sup it is trying to help save the stereo from cooking its self, and give you a chance to get it fixed. If that is not the problem then it may be easier to just buy a new one, because a fix may be expensive if you don't have any warranties.
