Member: 1675922 Status: Offline Thanks Meter: 61 | Missing PPVCC_MAIN - Ipad Air Any idea why could PPVCC_MAIN is missing when connected to USB? There are no shorts and PPVBUS_USB_DCIN is present. Also, D8100 is fine. This happened after nand desoldering: First due to heating PP1V8_NAND rail was shorted. Found a shorted capacitor by injecting power to the rail and check for heating. Then the board came to life, enter DFU -> Recovery...all OK. Next day, the board was dead: PPVCC_MAIN is missing... Thx, |
