RAJESH, the very first thing you want to do is to stop trying to turn the phone on. You may create more problems by short circuiting the phone. Then totally disassemble your phone.Clean all the part with isopropyl alcohol 90%+, do not forget to clean the connectors. Check your logic board for any burned or missing components. Once it is properly cleaned and inspected, replace the battery and reassemble. Re-evaluate for any further problems and let us know. Hope this helps, good luck.
