As noted, a shop will repair this, but a few low‑risk checks first narrow the fault and can reduce cost. The combination of colored vertical bands and the symptom changing when the AC lead is moved most commonly indicates either a power/charging jack or a video path problem; if the same artifact appears on an external monitor the fault is more likely on the GPU/mainboard.

  • Watch the screen during power‑on (BIOS/splash). Lines visible before the OS loads point to hardware; lines only after Windows starts suggest drivers — booting a Linux live USB or Safe Mode can confirm that.
  • Test with a known‑good external monitor and use the laptop display toggle (Fn + display key). Internal only = panel or panel cable/connector; internal + external = GPU/mainboard.
  • Power tests: boot on AC only (battery removed) and try a different compatible charger. If wiggling the AC lead or moving the DC jack changes the display, suspect the jack, cable, or a local power rail.
  • Flex test: open/close the lid slowly while powered on; changes with lid movement point to the LVDS/eDP cable or hinge damage.
  • With power removed, reseat accessible items (RAM, removable drive) and visually inspect ribbons and connectors. Follow ESD precautions.

Immediate backup of important files is advised. Panel or cable replacement is usually cheaper than a motherboard swap; GPU/mainboard faults generally need professional repair. Avoid DIY reflow attempts — they are unreliable and often temporary. When presenting the machine to a technician, listing which of the above tests changed behaviour shortens diagnosis.

Sounds like there is a bad connection in there somewhere. Your only real option is to take it to a professional.
