LCD Monitor not working Answered

i have a lcd moniter (acer V233H 22inch)
but overnight it stoped working it will turn on  then display a black screen 

PS my cable works if you need more ifo than that comment


The most common problem is the back light is out. Does anything get displayed when you go through the screen's menu and settings? If not try shinning a bright light into the screen and see if you can see the image. If you can it's the back light and it's likely a cap has blown in the inverter. Which can be easily replaced.

it does show a screen that says cable unpluged when its unpluged if i plug it into my hdmi adapter it says no signal but when it gets plugged into my computer it turns black so all i see is the back light

PS my cable and adapter work i testeded them on a tv

Never mind after my cable fell out i re plugged it in(thats was the tenth time) and it magicaly works again but thanks anyways
