step 1: measure 2 resistances here, if lost -> tracking to line and lifting or replacing the wire (yellow frame) on line.
step 2: Measure the capacitors (orange and purple frame) -> isolate and remove (purple), with orange capacitor ->replace same value.
step 3: take a look at the resistances (green frame) just error when drop in water and rotten.
step 4: replace chip DAC (Amplified sound). the next wire haven’t found error yet.
Note: In reality, Speaker of Ipad mini was error at any sides -> measure the resistance, if have ->replace chip DAC , rarely error capacitor, resistance around. IC code different iphone 5c, 5s, so don’t know it can be use for each other or not. Will be updated later.
