I have a Sony Compact AV System DAV-S400. Recently, the sound to the left channel has started to become intermitent. When you play a DVD or listen to the radio, the front left channel seems to cut in and out. Sometimes you can be using the system for a while before it happens, other times the sound goes almost straight away. I have tried using one of the other speakers and the problem still occurs. There doesn't seem to be a problem with the connection into the rear of the system but I'm not really sure what I should be looking for. Everything else on the system works perfectly, including the other four speakers.
Many thanks for any advice you may have,
The socket that goes to the headphone jack at the front, should be soldderd if u have the (HP THEATER) come up on the display without haveing headphones plugged in, other wise re-solder the speaker out sockets on PCB again or failing that re-solder the output chips that are in a row with a piece of pcb on top that should fix the problem.

Hi, Yes, tis unit has 2 video inputs at rear so you can connect any other dvd player sound (analog or digital) to get 5.1 channel surround sound from DAV-C770 speakers. Click Sony Support to download user manual copy of DAV-C770 that has more details about connection setup. Hope this info will help you. Thanks.
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 !
I have exactly the same prob and I belive that it is in the amp module?! I am going to take mine in for repair as my other sony HT amp has just give up the ghost, (STR-DE435), it has a protector prob and is probably not worth repairing, although it is a great amp.
If anyone knows the solution to this prob it would be great to hear it!!!
