iPhone 5c completely dead, no power
i have an iphone 5c which is just completely stone dead. i have tried a brand new battery with no luck, tried reconnecting any cables going to the logic board and still no luck, i have inspected the logic board and charging port assembly which have no signs of damage whatsoever. i had heard about the charging ic going bad on iphone 5c's but by plugging in a new charged battery would still mean that it would boot up but not charge right?
also a few things to note. i have this charging brick which generates quite alot of electrical noise, if i plug in a working device the noise would go away and the device would start charging, but if i plug in this phone the noise only partially goes away.
