What are the exact symptoms when you turn it on? don't leave anything out. does it make any specific noise that you recall? does it seem to cycle on and off without fully coming on while making a squealing noise from the back of the set only stopping when the set is unplugged? has any service at all been performed to this set prior to this problem?

Pwr-0501ssb-dmp-pcb no sound

The best you can try the same at Mumbai where there are many shops in the Lamington road but I fear that the PCB will be available.
Try for a good service shop to do a final check for a component level service.

Replace the motherboard (part # WR55X10942) but be careful to check that the evaporator fan (inside the freezer) turns on when you power up the refrig again. A bad evaporator fan motor can take out the motherboard. If compressor starts with new board but not evap fan, unplug immeadiatelly and replace the evap fan motor to save new board.
