The lines start at any position on the screen and it then works down and up until it fills the screen with these line. This total clears up by applying pressure on the laptop base or giving it a slight twist on the base(the lcd screen is not the problem.) It could work for quite awhile w/o this problem or could do it repetitvely after it has been cleared by base manipulation mentioned above.

Re: Aspire 5600 gets horizontal lines on lcd
The horizontal line means that there is a loss connection in the horizontal projection of the monitor. This can be resolved by fixing the horizontal panel board that gives error. this require quite expert in the LCD troubleshooting. However, if you believe that you can do it, ok you may proceed.

More than likely it's the lcd screen and will have to be replaced. I
could be the video card, but most likely the lcd screen especially when
you can put pressure on the screen and cause changes. To isolate the
problem try connecting another monitor to the computer. Borrow a
monitor from a neighbor, friend, relative or co-worker and connect it to
the laptop. If the Borrowed monitor displays ok, then the problem is
with your lcd screen and the video card is ok. If the Borrowed monitor
displays the same as your lcd screen then the problem is with your video
card inside the computer.
Plug in an external monitor and see if the
display shows up on it. It can be any kind of monitor even the old big fat crt
monitors as long as it has a vga cable to connect to your computer's vga
port. If so that proves your video card is ok. The video will show
on most systems when you reboot without you having to do anything. Some systems
will require you to hit the FN (Function key) + F1 thru F12. Hold down
the FN key then hit the correct key for displaying on the monitor (F1 thru
F12). The correct key will normally have CRT/LCD on it or it will have
the icon of a display.
Once you narrow it down to the lcd screen as being the problem
you might try taking the lcd screen apart to reseat the lcd cable on the
back at the top of the lcd. Just unplug it and plug it back into the
connector. You can also try doing the same where the lcd cable plugs
into the motherboard. Just pull it out and put it back.
sounds like the LCD panel may need to be replaced. To further check it, try to test if the same issue happens when you connect an external monitor to the laptop. Also, go to the BIOS screen and see if the same line are showing. If no issues with external monitor and line also shows in the BIOS, it would confirm the issue is specific to the LCD of the laptop. If within warranty, you can refer to Acer for repairs and/or replacement. If out of warranty and in doubt, see if you will get other advise from other users, or have a local tech verify it, whichever works for you.
