vivo y20s no display problem
na try kuna sa mga lcd ayaw mag display kaya
Ginawa ko nag tester ako voltage reading muna
Ako sa backlight normal naman 3.7v
At lcd voltage ay normal din yung VREG_L9A 1.8v at sa LCD_RST 1.8v din kaya ginawa ko diod mode naman ako gamit kayo schematic diagram para ma sundan niyo tapos nag tester ako isa isa sa mga pin out ng LCD connector
Ang pin out ng LCD_VSN ay dapat O.L ang reading sa diod mode ay naging 004.7 papunta po ito sa charging IC kaya pinalitan ko ang charging IC naging normal na ang reading back to O.L na may half shorted po ang charging IC
