Magandang araw/gabi sa lahat
May ibahagi lang po ako na kunting kaalaman.
Unit:
iPhone 6
Status:
No Display, Black Screen
Action Taken:
Check LCD Socket Voltages
Check for possible cut/open filters
Replace U1501 ic
Screenshots o Actual Pics
Checks this voltages if present, before doing hardware works.
If ~3.8v is missing possible only FL2024 is open, other thing will be the diode D1501 and the U1502 ic
If 1.63v is missing possible only FL2050 is open, other thing will be the power ic U1202
If 1.8v is missing possible FL2036, FL2035, FL2039, FL2027 is open, other thing will be the U1502 ic, in the worsest case is the CPU U0201
If ~.06v is missing possible corresponding inductor is open, namely L2041, L2042, L2043, L2044, the worsest case is the CPU U0201
If all this voltages is present possible U1501 ic is the problem
Proceed sa hardware, replacing the U1501 ic also called as display boost ic
After Replace the Display Boost U1501 ic
Thanks for viewing my thread !
Sana kahit papaano makatulong !
