Is it still under warranty ?? Have you tried a different battery ??
Need more information.
I am trying to fix a friends samsung (sgh-t599n) and I'm getting no where. The phone wont turn on at all, no led light indicators, no sound/vibration, no screen image at all. I've tried all sorts of tricks including removing the battery, holding down the power button, plugging it in with no battery and doing the same. I've tested the battery and of course changed the power cord. I've pulled out the power button to insure it wasn't stuck. I dont really know where to go from here. Also when i plug it into my pc it continually connects then disconnects about 10 times then all I get is the disconnect chime over and over....Any suggestions would be appreciated
