A short diagnostic summary and safe next steps based on the symptoms in the thread (small horizontal band showing the Windows logo; tapping the case changes the band width).

That behavior usually means the monitor’s panel electronics are still receiving video but some internal timing/drive connection is failing — common culprits are the panel’s row‑driver/gate outputs, the T‑CON/timing board or its ribbon (LVDS) contacts, or failing power/inverter parts. A failing gate driver or a loosened tab/ribbon often produces a single horizontal stripe that can change when the case is pressed. (ifixit.com)

Quick, non‑invasive checks (do these before opening the case)

  • Open the monitor OSD/menu: if the menu fills the whole screen, the panel is still being driven; if the menu is also limited to the same stripe, the fault is inside the monitor.
  • Remove the video cable: if the monitor’s “No Signal” or self‑test screen shows the same line, the failure is internal (not your PC or drivers). LG’s troubleshooting advises this exact cable‑remove check.
  • Try a known‑good cable and plug the monitor into another computer or laptop to rule out the graphics card or cable. (lg.com)

If the problem is internal (what to expect and what’s safe)

  • Reseating the flat ribbon connectors to the T‑CON and the T‑CON-to‑panel ribbons sometimes helps; applying gentle pressure in the right place can temporarily change the symptom (diagnostic clue). However, opening the case exposes high voltages (CCFL inverters can be hundreds of volts) and charged capacitors — only proceed if comfortable and experienced. Inspect the power/inverter board for bulging or leaking electrolytic capacitors; those are a common, repairable cause on older monitors. (ifixit.com)

Practical recommendation

  • If the unit is under warranty, RMA it. If not, compare the shop quote for T‑CON/power‑board service vs buying a low‑cost replacement — for many small/older LCDs the repair cost exceeds their market value. Do not continue hitting the case; that risks further damage. If choosing DIY repair, photograph connections before you disassemble and discharge capacitors or get a pro. (lg.com)

Notes tied to thread: ’s tapping observation is a useful diagnostic clue pointing at connectors/T‑CON/gate‑driver issues; ’s and ’s posts about swapping settings/cables are reasonable first steps, but the OSD / No‑Signal test above narrows whether the problem is the PC or the monitor itself.

how old is it and have you tried it on another pc or fiddled about with the settings. If the answer is more than 3 years and yes but with no luck then bin it its prob dead!

Member Avatar for DiNeSh_123

i cant fiddle with the settings cause i am barely able to see nything in the horizontal line, but yeah when i just give it a punch on the side of the monitor the horizontal line widens from 5 centimeters to 15-20 centimeters but after few seconds it again shortens.

the monitor is above 3 years old another wise i could have gotten it replaced.:(

computer display settings is higher than the monitor can handle,.
when computer starts to boot up start hitting the f8 key to go into safe mode,when you get there right click on the desktop and go properties /settings and change screen resolution to 800x640 ,save settings and Reboot computer .
