When I take a picture the picture is all black

I just tried something that I read a few days back tried it then but just tried it again. I held my Canon Power Shot S3 SI Camera Lens up to a Very Bright Light and started Taking Pictures started in TV mode then kept switching modes but taking lots of pictures in the different modes kept checking after taking a few I could start noticing that the screen was getting lighter and lighter with each picture that I took ... and Finely it started looking more and more like a picture.. and now my baby is back working...... thanks to who every the person was that posted about using a light to get her the Death of the Black Screen working... Just a little hint make sure that the light is really bright a flashlight did not work the yesterday for me so today a used a lamp and now me and mt Camera are both doing the Happy Dance .... Hope This May Help Others Who's Cameras Have Been Hit With The BLACK SCREEN OF DEATH....hope this works for you like it did me.:)
