#1 Asus R556L - Brak obrazu na matrycy X555LD REV 3.3

Mam laptopa Asus R556L z płyta o oznaczeniu X555LD REV 3.3, która miała lekkie zalanie na złączu LVDS i pinach 37-40. Złącze wyczyszczone, na matrycy brak obrazu. Obraz jest na zewnętrznym monitorze po HDMI.

Brak treści na matrycy po zaświeceniu w nią. Podłożona nowa matryca i bez zmian

Brak wyjścia 3V na układzie U4530, po zrobieniu mostka między pinem 5 a 1 pojawiło się 3V na złączu matrycy

J4520:
2- 3V
3- 3V
4- 3V
21- 3V
27- 3V
38- 19V
39- 19V
40- 19V

Nic się nie grzeje w okolicy. Gdzie szukać problemu?

Po odłączeniu zasilania od płyty głównej widać na matrycy mikro przebłysk, zanik lekkiego podświetlenia.

Przy okazji wymiany złącza matrycy, wymień także rezystory R4528 (100kΩ) oraz R4530 (10kΩ), bez względu na to, czy mierzą się poprawnie, czy nie.
