Hello friends,
I am having IBM ThinkPad R51, around 4 years old. The system is working fine. Recently it started showing single thin line. After some days another line start appearing.
I shown the system to laptop engineer. He suggested me to replace entire screen.

Is this really the problem of LCD screen or some other problem? Any suggestion is highly appreciated.

A compact diagnostic note to complement the thread: the original report from and the followups by , and point to two common causes (panel vs. cable), but a few quick, objective checks will show which is at fault and prevent an unnecessary purchase.

  • External-monitor test: attach an external display and duplicate the laptop screen. If the external is clean while the laptop shows the thin vertical line(s), the fault is inside the display assembly (panel or internal cable). If the external shows the same artifact, suspect the video chipset or motherboard.
  • Pre‑boot/BIOS observation: watch the screen during POST/BIOS before any OS drivers load. Lines present at that stage indicate hardware. Lines only after the OS loads suggest a driver/software issue.
  • Lid‑angle / wiggle check: change the lid angle slowly. Lines that change, flicker, or disappear with lid movement usually implicate the hinge/flat ribbon (LVDS) or its connector. Lines that remain perfectly steady regardless of angle point toward the panel’s internal column/driver circuitry.
  • Reseat and inspect connectors (only if comfortable): with power removed and battery out, remove the bezel to inspect and reseat the LCD ribbon at both panel and motherboard ends. Photograph connections and use ESD precautions; oxidation, a pinched cable, or a cracked conductor are sometimes visible.
  • Workaround and parts: an external monitor is an immediate workaround. If a replacement panel is needed, match the part number printed on the back of the LCD (not just the laptop model) or confirm the panel’s FRU with a parts supplier.

Power should be removed and the battery taken out before any bezel removal; ESD‑safe handling is recommended. For an older R51, used panels and cables are commonly available, so the diagnostic sequence above helps determine whether a simpler cable reseat/replacement or a full panel swap is the correct next step.

ok i'll say no ,you believe me or a laptop engineer.
im no engineer but i have to agree with one !

I had a problem on a T series where the internal video cable (ribbon type) broke down due to heat and caused artifcats on the screen. Maybe a similar issue?

I would agree with the engineer though, new screen is probably the wy to go.

When I changed the LCD panel itself, I found that the source of the problem is the panel, not the video card, not the wireing... You only need to drop out the old LCD panel and get a new one. You cannot repair the wrong panel.
