My Sony G520 all of a sudden has these faint diagonal lines (about 30* angle) going across the screen. (They're about the same brightness as the lines for the aperature grill). Usually these lines only appear when it's changing modes or just turned on, but now they're not going away. What do you think it could be? Could it be the video card? I tried a higher refresh rate and it just makes them closer together.
Thanks
