Would really not recommend 'bridging' it with wires until the facts of how it occurred in the first place are known. Having said that, I have just replaced these in the past and the drive worked fine afterwards with no other components seemingly affected....
Good luck... :)

Why did You Remove The Capacitor .Also The Bottom Of This Definately Has Voltage IMHO As There Are Capacitors Bridged To Ground From There .

Which CaPaCiToR are you talking about?

Could the "4" be part of the date code, ie 2014? That seems to fit with the JS3 and JS4 examples that I have found.
As for the grounded underside of the package, I would expect that it is intended for heat dissipation and would have no electrical connection to the chip's die. Perhaps this chip is different?
Would you be able to measure the voltage on the output side of this chip? I expect that it would be 5V, ie the same as the input side.
