iPhone 6 PP1V8 Oscar 0 Volt
Hi,
Iphone 6 connected to power supplay 4V will boot until 0.07a - 0.09a and LOOP.
LCD Blank , Not in Recovery or DFU Mode .
Tested Tristar before and after replace 1V8 - 3V0 - 5V0 Lines Ok.
Tested Tigris 3V0 and 5V0 Lines Ok
No Short on VCC Line
PCB Not Heat
No water damaged.
Due Low power amp Loop i suspect to 1V8 SDRAM.
Start to Test all 1V8 lines and i fund 0V at line PP1V8_OSCAR.
IC - U2203 c2247 and c2248-1 instead of PP1V8_OSCAR has 0V.
IC - U2205 c2270-2 instead of PP1V8_OSCAR has 0V.
IC - U2205 c2272 instead of PP3V0_IMU has 0V.
From where PP1V8_OSCAR is taking power ? While Tristar and Tigris 1.8 are OK
Any Help will be highly appreciated
