#1 Lenovo Yoga C930-13IKB - brak obrazu na matrycy

Witam,

Model laptopa: Lenovo Yoga C930-13IKB
Model płyty głównej: EYG 70 NM-B741 Rev 1.1

Laptop włącza się, ale nie wyświetla obrazu na ekranie. Na ekranie zewnętrznym obraz działa prawidłowo za każdym razem. Kilka razy udało się, że laptop włączył się i był obraz na ekranie, ale jak wyłączyłem laptopa i włączyłem ponownie to już nie było. Na zewnętrznym ekranie wszystko śmiga OK. Bios zrobiony i nadal jest taki sam problem. Laptop po zalaniu.

Dzięki za pomoc.
