Witam.
Laptop: Acer Nitro 5 AN-517-41
Płyta: LA-L031P Rev 1B
Matryca: NE173QHM-N76 B8.0. QHD 165Hz 40pin
Objaw uszkodzenia: Pionowe i poziome pasy na ekranie

Wykonane czynności: Pomiary na kondensatorach sygnałowych (wszystkie sygnały mają powyżej 1MΩ i rezystancje są symetryczne). Wymieniona matryca LCD (niby na nowa, ale wygląda jakby ktoś zmienił jej taśmy na rantach na taśmę izolacyjną) i efekt taki sam. Sprawdziłem również SVODem taśmę LCD. Na teście "cable" chyba ok, na teście "motherboard" dwa sygnały dziwnie przerywają, ale same z siebie, nie na skutek poruszania taśmą.

Dodam jeszcze, że matryca UHD 60Hz działa normalnie.

Zamieszczam zdjęcia i film jak wygląda test "motherboard" SVOD, może uda Wam się coś podpowiedzieć. Byłbym wdzięczny.

Masz tu ewidentnie matrycę słabej jakości lub źle zregenerowaną. Wymiana matrycy na nową załatwi problem.
