Try opening the monitor disconect the display panel from pcb power on amd then connect ur display panel. Hopefully display will be remaped when u restart the monitor
Sounds like your lcd screen is bad and needs to be replaced. Try
connecting an external monitor to the laptop. Borrow a monitor from a
neighbor, friend, relative or co-worker and connect it to the laptop.
If the Borrowed monitor displays ok without the lines, then your video
card inside the computer is good but your lcd screen is bad. If the
Borrowed monitor displays the same lines as your lcd screen then your
video card inside the computer is bad.
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 the video shows on the external monitor that proves your video
card is ok, ,but your lcd screen is bad. 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.
Hook a spare monitor to the video output, if picture okay the LCD panel display will need to be replaced, go to www.ebay.com type make and model of laptop, refine search to screen. But if both show the same symptom it is the video graphics card.
Sounds like your lcd is going bad. Try tapping the lcd on the back of
the lid and see if the lines flash or appear. Try connecting another
monitor to the computer. Borrow a monitor from a neighbor, friend,
relative or co-worker and connect it to the computer. If the Borrowed
monitor displays ok without the flash lines then the video card inside
the computer is good, but your original lcd screen is bad. If the
Borrowed monitor displays the flash lines like your lcd screen then your
video card inside the computer is bad.
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.
No DisplayShine a flashlight on the dark screen to see if youbarely see the icons on the desktop. If so, then the LCD Inverter isbad.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad
Either your lcd screen is going bad or you could have a loose lcd cable. Either one will require you to disassemble the lcd screen. Try connecting an external monitor to your laptop and see if the screen image displays ok on it. if so that means your video card is ok, the problem is with the screen. You'll have to hit the FN (Function Key) + (F1 thru F12) key to get the image to display on an external monitor. It can even be one of the old fat crt monitors as long as it connects to your laptop's vga port. Hold the FN key and hit the corresponding key that allows the external monitor to display. Normally the correct F1 thru F12 key will have the words lcd/crt or an icon of a display on it.
This issue is due to the malfunctioning of the screen or due to any other internal hardware malfunctioning of the notebook. To further isolate the issue, I request you to connect the external monitor and check.
Once after connecting the external monitor, please tsp Fn+F3Switch between the display and external monitor in the following order: Display External monitor Display and external monitor
If the external display is fine then the issue either could be due the malfunctioning of the display cable connector between the screen of the notebook and motherboard or due to the malfunctioning of the screen.
As this the hardware issue, Please contact the nearest repair center to get it resolved.
It may have one of reasons: 1. "Dirty" supplying voltage in the monitor - check all electrolytic capacitor. 2. Bad controller chip - check if it gets extremely hot when working, also you may see darkened area on other side of the PCB where that chip is located. 3. Loosed connection between controller PCB and the display itself - disconnect the cable and clean contacts, especially of blade connector on display side, check if there are some overpressed contacts.
