    black bob (sic blob).....rajat, yes, as you state it is an IC. The packaging format is "un-potted" or "un-packaged". This is generally done with very high volume PCBs where saving $0.02 means adding 6 figures to profits....sadly, it also means that the device is so cheap to mfg that they do not intend for it to be repaired.

    Ideas?

    1) Check & verify the battery/power connections

    2) Buy a new one.
