The LCD is broken and needs to be repaired. That green glitch was caused by damage to one of the traces going to the LCD. Essentially the screen itself was broken and when the controller (that's connected to the LCD) tried to power the screen it got damaged, thus the black screen. This is very common on the S4. Luckily, replacing the screen is quite easy. iFixIt has[guide|16540|an excellent guide] available.
