It's unlikely to be a hardware failure. You probably just messed up the system files by changing so many ROMS.
Make a backup if you don't already have one
Do a system reset from the settings menu (note that this will delete your user files!)
Boot to recovery mode and choose wipe cache (recovery mode: remove battery for ten seconds, replace. then volume up + home + power)
Use Odin or Keyes to flash a full stock firmware image (replace system files)
More than likely this will fix your GPS
You will need to reinstall the ROM you ended up choosing, apps, etc
