Witam, trafił do mnie tv kolegi, który pryskając Cleanem do szyb delikatnie go zalał :-). Po tym incydencie tv się uruchamia, lecz matryca świeci na biało. TV pracuje na platformie BN41-02152, napięcie VCC na płycie i t-con 5,40V. Bezpiecznik na t-con sprawny z napięciem 5,40V. Rozebrałem matrycę, pomiędzy warstwami slady cieczy, przeczyściłem izpopropanolem i wysuszyłem .Tv reaguje na pilot, wiem że biały ekran wiąże się z brakiem zasilania matrycy. Co jeszcze sprawdzić?

Chodzi Tobie o driver na T-con czy na mainboard?
