back light and LED indicator not working

[advanzd]

Recently my xperia SP(c5303)'s screen stopped working. I think the problem is the backlight because if I point a flashlight at my screen and look at it from an certain angle I can see what's on it, so it's still displaying what it's supposed to. The led indicator also stopped working. in the weeks before today I had this issue as well

(/t5/Xperia-SP/Display-gets-pixelated-black-screen/m-p/974294#U974294 ) so it might have something to do with that. Any help would be really appreciated!
