While shipping my laptop, the laptop seems to have got a shock. The top 40 % of the screen is showing the correct display whereas the remaining portion shows vertical lines.
What could be wrong ? any help would be appreciated. I am attaching the picture of the laptop

Most likely cause: physical damage to the LCD assembly or its signal path. Vertical bands that occupy a fixed portion of the screen after a shock usually mean the panel’s column drivers, the T-CON board, or the LVDS/eDP cable running through the hinge has been damaged. Software or driver problems (as mentioned by ) are less common with this symptom, but are easy to rule out with a couple of quick checks.

A practical diagnostic sequence that isolates the fault:

  • Observe the image before the OS loads (BIOS/POST). If the lines appear there, it is hardware.
  • Capture the screen to a file (PrintScreen → paste into an image editor). If the saved image is clean while the physical display shows lines, the panel or its cable is at fault rather than the GPU.
  • Attach an external monitor. If the external image is clean while the laptop panel shows lines, the GPU is OK and the problem is in the laptop display path.
  • Gently vary the lid angle and feel the hinge area. If the bands change or flicker with movement, the hinge cable is suspect (echoing 's experience).
  • If comfortable and out of warranty, power down, remove power/battery and carefully reseat the display cable behind the bezel; otherwise leave this to a technician.

Repair guidance and cautions:

  • If tests point to the panel/cable, reseating or replacing the LVDS/eDP cable is the lowest-cost attempt; a failed T-CON or the panel glass/driver array will require panel replacement.
  • If the same artifact appears on an external display and in screenshots, the GPU/mainboard is likely damaged and repair is more expensive.
  • Do not open the case if the laptop is under warranty. Take appropriate ESD precautions when working inside, and avoid DIY if unsure.

Summary: shipping shock makes physical damage the leading suspect. The screenshot + external monitor tests are the fastest way to know whether the panel/cable or the motherboard/GPU needs attention.

I have also seen this happen if the driver is expecting the wrong screen.
