Vcc_Main shorting to ground pls help
Can anyone please help me with fixing an s7 edge.
First the Vcc_bat and vcc_main were shorting bit after I removed the big cap under the battery connector, the short on the battery connector was gone. But the Short on Vcc_Main is still shorting.
One day the phone was charging over night, in the morning the blue notification light was blinking and the phone wont turn on. After a couple hours the notification light shows nothing and the phone was dead.
Things I've tried:
I tried to remove the display ic but short is still there so i soldered it back on.
I replaced the U7000 and reflowed the other three ic's on this side.
I removed the cap under the battery port.
I tried the ice spray trick but it seems that nothing is getting hot.
I reflowed the ics on the back. (U7011, U8008, U7009)
After I removed the max77854 PM ic on the back, the short was gone so I ordered a new one, soldered it on but the short went back. I thought maybe the chop is bad so I ordered another 2. But same problem with them.
Update: After reflowing the Max77854 chip, the short on vcc Main is gone. When i put the Battery back on and try to charge the phone, the PMIC S535 is getting extremle hot. The Cpu also is getting hot but not as the PMIC.
