My wife's Cingular Samsung phone (don't know model - it's a flip-type phone, new in 2004, no camera, color display, free after rebate) had its display stop working today.
The display and keypad are backlit, the thing makes and receives calls fine, but intermittantly, the display doesn't work. It's been good at times today, and been not good at other times. Right now, it's not good.
It was not dropped and was not exposed to moisture or extreme temperatures.
Any ideas what to do?
