Dark Screen with Flickering Lines, Otherwise Works Fine

Dark Screen with Flickering Lines, Otherwise Works Fine
Hello, I have the HP Edition 20 gb Ipod 4th generation, model # MP102. Previous to this issue, I had replaced the hard drive inside it with compact flash solution at 64 gb, replaced the battery, hold switch assembly, and, in trying to fix the issue, replaced the screen. It had worked fairly well and easily for about a year prior to this issue arising.
