I850 my telephone screen is not working. i can not see anything the time in the front of the phone works but that is about it.

i just tried several things with my phone , off and on removed battery , pressed diferent buttons, etc. my phone screen is on, but can;t see any thing ekse, just a line down the middle of it. when i plug it for recharge it says device attached which is normal. but what is that skinny line down the middle mean? nothing else shows on it. i just tried several things with my phone , off and on removed battery , pressed diferent buttons, etc. my phone screen is on, but can;t see any thing ekse, just a line down the middle of it. when i plug it for recharge it says device attached which is normal. but what is that skinny line down the middle mean? nothing else shows on it.
