What does it show on the screen, completely black or white? There's a good chance the setting you have on manual mode is either severely underexposed or over exposed depending on what it shows on the screen. You can also try and take a picture of subject in auto mode then view the photo and do as what RioRico suggested and press the info button to look at the exif data. (ISO, Aperture, Shutter Speed, Etc.) Copy those settings in Manual mode then take a picture of the same subject with the same lighting condition and see how it comes out....hope this helps.
