Why does my Samsung home theatre system HT-C550 come on amd go off

buy a new one.

Sounds like it's stuck in it's power saving mode. If you've tried reset, checked all the connections, and kicked out the plug for a Cold Reboot and it's still no go, open the back, spit in it 3 times and hit it with a rock - or take it to a TECH because you've already done ALL that you are capable of, or you'd already know that.

If it is making any sound at all then it is "on".

Check your subwoofer function and level with Test Tones (page 29) and Auto Sound Calibration (page 30) and don't expect too much from an 8-lb 6.5" subwoofer and a multichannel amp that only draws 75 watts of electricity. Maybe place the sub nearer to a corner.

Looks like it is to do with the rear wireless speaker. Now, my problem is over. Its gone. I first turned the reciever on and then turned on the rear speaker wirel less on. No rear chk in problem now. Hope this helps. R.
