ANY help on backlight button issue?!

[unreal253]

wuts good yall.
i need to figure out wut kind of issue this is.
say my phone is on and screen is on. i press the 'Backlight' button(NOT the red/end/power ) on the top of the phone.. and the screen will turn off. Normal. Great. Okay now I go to press it again. The screen doesn't power on. I noticed the phone is definitely on and as if the phone is being used with no screen. The lights and controls works.

I tried flashing new roms of all sorts. I primarily use NRG roms. Can ANYone help me out here? I cant seem to figure it out. Can it be hardware, even tho it still turns the screen off?
