820-00138-A MBP A1398 2015: Charging IC blowing repeatedly

[Saurabh]

Hi,

The MLB was dead and there was no light on the MagSafe.
- No visible corrosion on the MLB. Found charging IC faulty.
- After replacement, it worked for a while and the charging IC blew again
- Tried with another IC, same.

Please help me with the next steps.

Was the machine working properly after U7100 replacement?
Was the battery charging?
Did you check PPBUS_G3H voltage without battery?
