Won't turn on or charge, have replaced battery and charging board
What next? If I replace the motherboard is that likely to fix it? I am new to phone repair, so I can't think that it's anything else, but I wanted to ask people with more experience first!
Background info: I got the replacement battery from ifixit (along with the excellent tools) and the charging daughterboard from ‘therepairshop' on ebay. Both went in without a problem, but the symptoms remain the same as they did when we discovered the problem one morning - the phone is completely dead. Won't turn on, apparently won't charge - no LED indicator, and leaving it plugged in overnight does nothing. Also, before I started the repair process I followed Samsung's triage process for resets, different chargers etc.
Hope that's enough background :)
Is this a good question?
