PSP Go Back Light on But Half is Black do I need NEW LCD? Help please!

I just bought a PSP Go & was told that sometimes it lights up & will play but then goes Black with Back Light still on. I thought it was a Software issue because it’s been modded so I did a Hard reset & it went Lit/Black and lines but NO Game or visible options though I do have sound. Is it the LCD itself that’s broken or does anyone have an idea on what it could be? I greatly appreciate anyone to take the time to read this & possibly help me.
