I have had my Samsung Tablet 10.1 P7510 since 2010. I had to go threw two replacement digitizers and I just recently replaced the charging port because I was having trouble charging my tablet. Every time I plugged in my charger I had to wiggle the cord around to get it to charge. So I just replaced the charging port and now my tablet will not turn on at all. Does anyone have any suggestions on what it could be? I was thinking about replacing the battery as well but do not want to invest more money into a battery when it could not be the problem at all. Any one have any advice on how to fix this problem or what could be causing it?
