Screen suddenly freezes then fades to grey then eventually black
I have a MacBook (13-inch, aluminum, late 2008).
A few months ago I started having an issue with the display.
All of sudden, the display freezes and then fades to greyish/bluish then eventually black. During that I can see some sort of scan lines as well. When it's black I still can change brightness of the display by F1/F2. So it's not completely turned off.
It goes back to normal if I play with tilting the display.
Just for a note. A couple of years ago my Macbook was accidentally sunk in water. But when I tore it down and dried everything it worked fine since then (except the battery which I had to replace).
By googling reading some posts here I found out that it might be either inverter board or LVDS/video cable.
I've checked the LVDS/video cable connector to the logic board and it seems fine.
I haven't gone further as I'm not sure what exactly causes the display issue.
Also I'm not sure if I should replace the cable.
Thank you in advance.
