Backlight circuit is working.
You have open line to LED strip.
Bad LCD connector, video cable, or backlight LEDs into display.
 
Yeah that what i thought, but wanted to confirm there wasn't something else that could cause the display not to work before i purchase a replacement display. Testing the cable first. Thank you
