Sounds like its broken. the black ink stuff could mean the screen is cracked and it has bled internally. I had the same problem (screen bleeding). the not-turning-on part could be because ur not using full batteries, the batteries are not in the right way, or the screen crack is shorting something inside and not allowing the device to come on. get it replaced. when you turn it on press the menu/ok button is there any noise, tune. this happens to me to show its entered the menu section. if you are getting this sound, then its turning on but the screen is cracked. if not then you have a dead camera or change the battery positions or use new batteries.
