    I have the same problem but don't really want to be taking the thing apart? Any other suggestions apart from an out of warranty repair job? Also I notice that there are not many authorised Sony repair shops around...

open the system and remove the cables (white cable) that are installed on the panel at the right hand-side.Replace the dettach cables after 10minutes,couple the system back and insert your cd.
i am sure it will work fine.

nb: the white cables are about 5cables at different location on the panel.

Hi, you have to unplug your unit and open it up you will see two printed circuit boards one slightly over the other at the back of the unit. You have to loosen the top one off so that you can get to the bottom one, turn the bottom over and take the protective copper board off wth care so that you can see the soldered joints. Check all large pole joints and re-solder as i had to do 14 joints also the brown capacitor was loose on my board and re-soldered that also. I found that the cable inside the unit that comes from the headphone socket,follow it to where it is connected to the bottom board, three of the soldered joint were loose and i re-soldered them also. Rebuild circuit boards into place dont forget to put the copper cover board back in place on the bottom circuit board. The above info i found on an internet site and followed the instructions my unit now works just as new. P.S. USE SMALL TIPPED SOLDERING IRON.

Power protector on sony surround sound system


Power protect is an error message that some thing is wrong in your sound system and requires qualified tech.

Normally that error message appears when unit got problem in amplifier output section, either it is speaker problem or some output chip is fried.

Sony compact AV SYSTEM DAV-S400


Hi Joey - I had exactly the same problem.

In my case, I followed the advice of others and took the thing apart. On the main amp board there is a large brown capacitor. Mine had come completely loose, so I soldered it back in place with a good amount of solder to make sure the contacts were ok. I also dabbed some solder on the headphone connectors on the same board (just follow the wire from the headphone socket to the board). Well, when I put it back together and tried it again everything worked perfectly, and it has so far remained free from the error. Hope that helps !

Protect


The protect message indicates that a problem was found in the output stage of the amplifier. Unless this gets repaired, nothing will work. As a verification that the speakers or the wires are not the problem, unplug all of the speakers and try again. If protect still is displayed, the problem is inside the unit.
