Hi A while back my screen went black, it has recently come back very dim (not usable dim), I tried cleaning the dust inside connectors attached to the board, used the FN bright buttons and the slider brightness in control panel with no results (some times it makes the screen go even darker or black not lighter at all very random).

I was wondering how I can go about fixing this without warranty and without spending a small fortune on a replacent screen as I think it is only something to do with the blacklight, Can anyone tell me either how and where to replace it in computer (pictures would be great) or how to clean it or if it could be something else, any help would be great.

The picture shows the computer works fine on my second screen and you can see the same image on the left but very dark and annoying.

Thanks
