When using the camera it says recording and wont take still pictures

Replace or repair

DSC-S930 does record sound and you can hear video clip sound by playback of Media Player in Computer.
This camera does not have inbuilt speaker for playback sound but it have inbuilt mic to record sound, transfer recorded movie clip in computer and play it with media player to get sound and picture.
Hope this info will help you.

Does camcorder show good picture in playback and does not give you live view to record?
or it does not power up?
Your post is not clear about porblme with camcorder and please intimate exact model number of camera too.

have you eset the camera to factory settings. procedure will be given in the instruction manual

You might need a source picture from a camera or off the tv so that the DVD has some sync pulses to actually record the sound. Some won't do anything without any pictures.

your mode switch is dirty/defective. the camera still finds itself in the movie mode.

If it plays back pre recorded tapes then there is nothing wrong with that section of the unit. Does it playback audio and not picture or does it not playback anything.
Also, when trying to playback a recording what is seen of the screen? Snow(black and white dots or wiggly picture?

The unit uses two separate circuits to record and playback tapes. Is any thing else connected to the unit while you are recording? If you are using anything plugged into other ports on the recorder it may not see the camera input causing it to not record anything..
