Sudeep Chatterjee, I'd start by double checking the work you did. Make sure that all the cables are properly connected. Check the DC jack to make sure it is properly seated. Then check the AC adapter for proper voltage. If it does have the proper voltage, plug it in and measure the voltage on the DC jack of your logic board, to see if it does work. It seems like you have a main power problem which occurred after your repair, so start with that first.
