(samsung t 555 ) Cant switch on tablet olso if battery is charged

I have a Samsung tab SM -555.The battery is still good but sometimes (a few times) I found it switched off and I dont know why (olso if I think the problem maybe can be the mini usb.One time after switching off the tab wont witch back on but afer "mooving something in the mini usb " I was able to power on again and use it (before I was able to power n the tablet only if the tab was connected at the charging cable). I think that it can be a false contact in the mini usb.Who can tel me the the order and functions of the various pins in the tab t555 mini usb?

Thank's

Check the charging port for debris and use something like a toothpick to clean it out. Shining a flashlight into the power will make it easier to see if it's physically damaged or blocked.
