My sony cyber shot dsc-w220 has a black lcd screen. All other functions work, flash, menu displays, just the screen is black and when I take a pic it is black.....any suggestions???

Sound like a malfunctioning CCD-image sensor. Rare, but possible problem with your LCD screenviewer (I dont believed, if you can see Menu icons)... in both cases (LCD or CCD) this isn't a job that you could solve yourself; this wrong include distorted images or abnormal colors, scratchy purple lines, blank or black pictures, and/or black videos with good sound being recorded on the camera's flash card.

I suggest check THIS LINK for additional details in this previous solutions for an Defective CCD (Charge Coupled Device) and next contact your Sony service. I strongly suggest (taking into consideration the age of your camera) to evaluate the cost of repair versus the cost of a new camera with similar features, before making a final desicion.

Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.
