J4D Buy a new one! Although it may be salvageable, it will definitely be unreliable and dangerous to use.
Roudykh I will definitely buy one tomorrow. I'm too far from the city now. I thought if i can fix it myself. Thanks anyway.
DNA it needs a bit soldering skills and it will be as good as new, but it appears you have no idea so as the guys said its better to get a new one.
