Look on the back of the unit to see if you can find a reset button. If not then you may have blown an internal fuse.

Happens to us, too. We do what the manual specifies: disconnect from the electrical outlet and connect it again. Works even though it is a consistent and annoying problem this equipment has.

SOURCE: Protect

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.

SOURCE: HCD-XG500 it says push power protect

Power protect tends to mean the main power amp chip has "blown" and needs to be replaced. It only costs about 20 dollars (10GBP). If you are handy with a soldering iron it is easy to do (after you get the thing to bits !) It is the big black thing on the big heatsink inside. The Sony part number is STK442 - 130. Seems a waste to throw the whole thing away for the sake of 10 pounds !. Hope this helps. Nik Howell (nh@totalise.co.uk)

Sony hcd-ec99i i have no sound from the speakers at all. I am not getting the protect message. please help


Check the simple stuff first

Is it muted?

Is the source selected sending signal (radio staion broadcasting, cd playing, ipod all the way ect)

Try doing some basic troubleshooting like,

see if all sources available yield the same result (TV, Radio, CD, Ipod, Aux jack)

When you turn the volume all the way up, do you hear an audible hiss from the speakers?(or use a test tone) If so, your amp is working and the problem is, your unit is not sending any signal to it.

If possible hook up your speakers to another system to rule them out, however I doubt that is your problem.

Here is sony's recommendation and a review video

Sony stereo protect mode


If "PROTECT" appears on the display: Immediately unplug the power cord, and check if anything blocking the ventilation holes on the back of the system after "PROTECT" disappears. After you have checked the ventilation holes and found to be all right, reconnect the power cord, and turn on the system. If the issue persists, contact your nearest Sony dealer.

Disconnect the speaker wires from the unit. If it still says protect when you turn it on, then the amp ic has been shorted and needs to be replaced.

The only thing I can think of is its goin into protection mode like an amplifier would, you maxed the volume out and it's protecting your speakers or you don't have the right voltage going to it, I can see you don't have it on a straight 120v plug and you might have the wiring wrong on the speakers to it might be too low of a ohm or too high
