Have an old cheap digital camera. It still takes pictures, but the LCD is faint and blurry w/vertical lines thru it. Can't hardly read the function menu's anymore. Is there any hope for it, or is it toast ?
Yep, probably toast. I vote with Stoney. But, you can try two things first.
Fully charged batteries or try to get at the board under the lcd with canned compressed air and a straw nozzle. (Hold can perfectly level so that the liquid propellant doesn't get in there.) Dust on the board might cause that condition but I am more inclined to believe that the display is shot. If it's and old cheapie, chuck it and don't look back.
