Hi all,
some days ago I was using my Inspiron 17R-7720, when I noticed that the screen was losing its bightness. Once I rebooted, the laptop makes 8 beeps at POST and I cannot load Windows. The screen has regular black vertical lines and there's a split screen at about 3/4 of the height.
If I run the LCD diagnostic, I can see the colors correctly. I tried to connect an external monitor through the VGA or the HDMI port, but it remains blank.
What can I do? Any thoughts?
Thank you.
