you need to clean it using isopropyl alcohol. that will involve completely disassembling it.

pcb I already cleaned in an ultrasonic cleaner. A few capacitors fell in and there is no pmbb layout because it was short
halo cześć,
0,06A przy starcie wskazuje na niski bilans energetyczny. W takich przypadkach warto przestudiować linie główne zasilania. W większości przypadków, jeśli ich parametry mieszczą się w normie szukałbym “korka” za PMU. Sprawdź porty LDO z MPU i CPU razem z liniami SOC. Niewiele dalej, bo od 0.09 zaczynają się spięcia pod procesorem, spowodowane przegrzaniem 7-ki przy zdejmowaniu shield’ów.
pozdrawiam,
