Image on the laptop screen has slight ghosting behind letters and icons. If you adjust the display and find the right position the ghosting disappears but it comes back if you move the display again. The laptop doesn’t have any ghosting on the external monitor. The ghosting appears only on the laptop screen.
1. Video cable failure.
2. Bad connection between the video cable and LCD screen.
2. LCD screen failure.
Possible troubleshooting steps and repair solution:
Most likely this problem is related to the video cable failure. The video cable transfers data signal from the motherboard to LCD screen and apparently, there is a short inside the cable. When you adjust the display, you actually flexing the cable. When you find the right position, there is no short inside the cable and the video goes back to normal.
If that’s the case, you’ll have to replace the video cable.
Before replacing the video cable try reconnecting it on the back of the LCD screen, just to make sure it’s not a connection-related problem. Reconnect the video cable and test the laptop.
If replacing the cable doesn’t help, most likely it’s the LCD screen failure. You’ll have to replace the LCD screen.
