Member: 1319762 Status: Offline Sonork: krisszmix Thanks Meter: 2 | iPhone 11 no power, U2700 changed. I got an iPhone 11 with no power problem. No water damage, no dropped. Checked the power measuring points, and i saw, there is no PP1V8. This voltage making from U2700. I changed it, now i have PP1V8, but when i pushed the power putton, the amper meter jumping up to 20ma,then power off. I measured the U2700 pad resistance, and i find the problem resistance B2 and D4 pads only 20 Ohm. ZXW say, i need 62 Ohm this pads. It is big difference, and this pads connecting to the Main processor. Is the Processor dead, is it possible ? If yes, i not need to make any hour to repair time...  |
