[HELP] S3 Wont turn on at all!

[JThurai]

SGH - T999 TMOBILE version

The whole day the phone kept freezing, and turning off. This happened about 3 times. But i was able to turn the phone back on after the first two times.
The last time, i was on fb and opened my gallery to send a picture, then the phone just froze, shut down and refused to turn back on.

I tried charging, no light, no vibration. Tried power,home volume up nothing came up. I can't do anything, it is basically dead.
With the battery in and charger in, i get no light

however when i take battery out, and put charger in i get a red light as if its charging for a few seconds
I still cant turn it on though

When i plug into computer, i hear a sound, but the comp says device not recognized. Please tell me this can be fixed

Also i have no warranty anymore...

EDIT: My phone is a pentaband unlocked version, I bought it in canada and use it with WIND mobile


Would JTAG work, or would i need a new motherboard?

It does have a one year warranty. Take it where you bought it for repairs/replacement.
