So this Phone arrived dead but after inspection I noticed damage on the backlight area of the lcd connector, so I immediately thought backlight but nope the phone was indeed dead
please check picture
and so I still checked the filters and backlight circuit but all was good and the lines checkuot in diode mode as well
And so I promted to boot on DCPS and it’s stuck at 0.178A
there is very small heat on the pmic area so I tracked that down anyways,
My tester board which is a USA model not sure if cdma or Gsm as well as this phone I think is T-Mobile or Att anyways
so what I found was
on
PP1V1_SDRAM was located nearby or exactly where the small heat is generated on the pmic this line was at 0.220 in diode and on my tester is at 0.050
I was hoping for a short but in this case well it’s harder but I wanted so see if this is just a different version of the board or I do have some cold solder below some ic like the cpu
