Needs a new charge port. If the port is soldered onto the board, i suggest getting a new tablet, however, most of the tablets use a flex with a charge port on it, try finding this flex/daughter board, but be careful, and make sure you bought the correct revision. If you could post pictures of your tablets motherboard (with just the back cover off) then i can tell you if the charge port is something that is soldered or is on a flex/daughter board.

I had one doing this same thing.
I replaced the charging port but when I plugged it in I got nothing.
The soldering looked fine under the microscope so I knew it had to be the battery or the board.
I did the battery connector reset several times until I got the screen to flash the back light.
Leaving it plugged into the original higher amp charger it would keep flashing the back light on and off.
Until it got enough power to boot the LCD. Then finally enough charge to keep the screen on.
Its a bad design on Samsungs part. The board doesnt allow the battery to charge enough before the battery can support the screen voltage draw. I think when the battery drains too much it can get to a point the board wont even charge due to this draw.

Ardit, you have to tell us a bit more. It is important that you let us know what you tried. We do not know what other people do or have suggested to you. Also, what do you mean by that "I tried to put off the connector of battery "?

oldturkey30 is correct about needing more info. Particularly, I believe the three most useful ones are, did you go a long period of time without charging your phone? 3-7 days or more while the battery was still inserted. In that case, as is for most any rechargeable device, when you plug in the correct charger the device will not show any usual signs of charging for a while, such as the LCD not turning on, a sound or vibration. Keep the charger plugged in, and it will start charging, I have waited 10 minutes to 6 hours for a a device to start charging. In reference to the 6 hour wait, that was a galaxy s3 with an over charged battery. Such as if you leavee it plugged in for long periods of time, the battery will start to drain faster and eventually die, then you would need a battery replacement.

CONTINUED...... The third one, was refered to by Alec Tocosh below.The ports in Samsung products are delicate little flowers. If you accidentally attempted to put in the male adapter in they easily break, or if you used the wrong male adapter that fit, outlet adapter, it could have also ruined the port, or something else. (Maybe there is a great plan devised by Samsung, to conspire to make their expensive product, easily, and simply breakable, in order to get more money from the consumers. But we can leave that for another forum.) Anyway from my experience, most galaxy 3 models' ports are not soldered, so you,or likely someone else (since this an old post), who likes to fix, disassemble, and reassemble for fun and or education could appreciate some basic information. Well good luck, and always save your spare parts.
