How to Reset a Sony DAV-SB100

Updated April 17, 2017

The Sony DAV-SB100 is a home theatre system with many advanced, programmable features. It is also designed with sensors that allow it to protect itself from situations -- such as overheating, or being connected to the wrong kind of speakers -- that might damage it. Like any computerised device, it can fall prey to memory errors that cause it to lock up. In case of malfunction, the DAV-SB100's main stereo unit can be reset to factory defaults.

Turn the DVD player off by pressing the Power switch in the lower left hand corner of the control panel.

Unplug the power cord.

Leave the unit unplugged for at least 2 minutes.

Plug the power cord back in.

Turn the unit back on by pressing the Power switch.

Remove the two batteries by pushing the hatch on the lower rear of the remote down and lifting the batteries out.

Press every key on the remote two times.

Replace the batteries in the remote.


If the DVD player simply isn't playing discs, make sure there's a valid disc in the player and that the laser doesn't need cleaning before you reset the unit. As you're resetting the remote, make sure none of the buttons is stuck down. This can cause the remote to ignore other button commands. It's a good idea to replace the remote batteries, so you can eliminate low battery power as a cause of the problem.


Make sure the DVD player is turned off before you unplug it from the wall. Failure to do so can damage the unit. Never unplug the DVD player while a disc is in the drive. Even if the disc isn't playing, it is spinning, so unplugging the unit could cause the disc to jam or be damaged.
