Note when the defect appears

Check whether lines appear at the manufacturer logo, only in Windows or in one application. Are they constant or affected by workload? Take a phone photograph. A single symptom is not enough to choose a replacement component reliably.

Compare an external display

If you have a compatible monitor and a known-good cable, compare the image. A good external picture points inspection toward the internal display and its connection, but does not rule out every board fault. Defects on both displays call for checking software and graphics hardware too. This is a diagnostic clue, not a final diagnosis.

Do not press the panel

Pressure and repeated lid movement can make damage worse. Tell the technician if moving the lid changes the picture, but do not repeat the test forcefully. Black patches after an impact and visible cracks require a different assessment from flickering limited to one application.

How the repair is selected

The panel, cable, connectors and display circuitry are checked. Kmvle, MB in Vilnius selects a screen by model and specifications, not diagonal size alone. Mention drops, liquid exposure and previous repairs. Work is agreed before ordering a panel; some models require a special part order.
