I fixed the problem by replacing the battery!
Meer informatieSo there were two not so good looking components in the area around the LCD connector close to the backlight IC. Darkened capacitor, i replaced it. And one little darkened core-ferrite bead which i also replaced. And problem solved! The LCD lit up! I believe that the core-ferrite bed was bad, because its functions are to block noise for the backlight IC.
Meer informatieThe home button’s flex cable caused the problem, because i tried connecting only the LCD and it works fine, but when i connect the home button to the board, the phone immediately goes off, or when i connect the cable while the phone is off it doesn’t turn on. Now i saw oxidation where the home button connects to the flex cable on the back side of the screen.
