Witam,
Model: MSI MS-1758
Płyta: MS-17581 VER: 1.1
KBC: ENE KB3930QF
CPU: Intel i7-4712MQ
GPU: Nvidia GeForce 840M

Na laptopie brak obrazu na matrycy. Tylko podświetlanie. Po jakimś czasie przy otwieraniu i zamykaniu klapy matrycy pojawił się dym i zapach spalenizny.
Dym na taśmie matrycy przechodzącej z obudowy przez zawias. Matryca przestała być też podświetlana. Wypiąłem taśmę matrycy aby nie pogorszyć sytuacji.
Po rozkręceniu laptopa na płycie widać przepalony element Q3 znajdujący się po drugiej stronie płyty zaraz za gniazdem matrycy.
Można prosić o identyfikację tego układu?

Jakie powinny być pomiary po wymianie tego układu? Mogło się coś jeszcze uszkodzić?
Prośba o pomoc jakie pomiary mam wykonać obecnie i po zakupie nowej taśmy?
