Help black screen on lg esteem

[Android Question]

I have an lg esteem and the screen went black on it all the other buttons light up the screen even lights up and have a rainbow colored line down the middle of the phone the line changes colors but no picture not even the lg logo that pops up when you turn the phone on. I answered it one time and it works so im thinking that it's something with the screen I was going to replace the lcd display screen in the phone to see if this would fix it. What do you guy's think.


Oh ya I also tried taking the battery out and putting it back in but no change still black.
