Why black screen, gradated screen when working and screen freeze?

Texto:

-I have been having issue of intermittent black screen. Then screen worked for some time then started showing gradated screen. The top being lighter and the bottom being darker. I replaced the LCD display thinking that would solve the problem, but it still has the gradated screen and it freezes up. I opened it back up and checked connections and cleared out the dust on the fans. Now, it's back to a black screen. I took a picture of the power source while I had the computer open because it looked odd. If someone could tell me if they think the power source is bad or if maybe the inverter is causing the issues, I sure would appreciate it!
