The problem is most likely something you did in your rework. Some common issues in no particular order:
-> New component soldered to the wrong place.
-> New component has the wrong value, for instance replacing a 10,000 ohm resistor with a 100,000 ohm resistor.
-> Solder blob that is shorting out two terminals that shouldn't be connected.
-> Electrolytic cap wired in reverse.
-> Bad (cold) solder joint on one of your solder connections.
Good luck.
