Sony Home Theater Problem: Protect mode keeps coming on

by voodoodoodoo / August 5, 2007 3:04 PM PDT

I got a Sony HT-DDW670 Home Theater in a Box system a while ago via Ebay. The sound is good, but we keep having a problem when trying to watch movies. Often, the dialogue seems much quieter than the music and other efx, so we turn up the sound to hear it. But then if there's a loud part, the sound goes off and the unit flashes "Protect", then turns itself off.

We don't have the sound up particularly high -- maybe 40-50. Yet it will continually do this. Could this be a problem with some of the speaker wiring? And, in general, do others have this problem where dialogue is much quieter than music? Perhaps there's some setting that I've missed.

Forgive me, I'm a relative newbie with home theater...

Sony HT-DDW670 Home Theater in a Box System

One other note -- after it turns itself off, if we press power it will turn on again immediately and if the volume is a little lower, will continue to work fine. It's just those times when we want to hear the dialogue...

Have you balanced you speakers???

There should a routine to balance your speakers.
My guess is that the center speaker level is to low, you need raise the level of just the center speaker. Look thought the owners manual on how to do this. John

I had this same problem...

You have a "crossed" wire somewhere {or a basic short circuit}... For instance... With mine... I split and spliced 2 seperate wires {B/BW} together to make a longer run... and the splice where I put electric tape slipped off/came undone and they were touching each other {bare}. Thats why my system went into protect mode {for obvious reasons}... check all/any splices and where the speaker wires connect... I can almost guarantee this is your problem.

Since I use mine mainly for movies I have the center to + 10 {or whatever the max is} everything else around +3/4 if I remember correctly.

Honestly it's not a bad little system at all for the price! I love mine!!!

Good luck!
