Witam szanowne grono . Na stole ACER A515-45-R3GZ mb: ZAUR DAZAURMB8D1. Laptop po mikro zalaniu - okolica zaznaczona kółkiem na pierwszym zdjęciu - dwa elementy. Po uruchomieniu miga podświetlenie matrycy. Próby przelutowania przyniosły pozytywny skutek ale na chwilę. Po krótkim czasie niestety matryca znów zaczyna migać. Pierwszy prawdopodobnie rezystor został wylutowany i oczyszczony - wlutowany ponownie. Drugi natomiast - kondensator lub cewka... (na zdjęciu po wylutowaniu zaznaczone kółkiem pola lutownicze) Niestety element tak mały, że raczej nie uda mi się go wyczyścić i wypadałoby go zastąpić innym. Pytanie co to może być za element i czy oba elementy mogą być odpowiedzialne za defekt ?

Hello!

The components are as follows:
A= Capacitor 100nF/6.3V, package 0201
B= Resistor 2.2Ω/5%, package 0402

These two components may be responsible for backlight flickering. I suggest you to replace both.
