@mrfixit1978, Did you power off the phone and/or disconnect the battery before disconnecting or reconnecting? Did you make sure to keep track of and put the screws back in their same hole they came out of? It does sound like you damaged the Back light circuit and not a "Fried" Logic Board. You will need to have Micro Soldering done to either replace the Filter(s), or possible the Driver, Diode and Coil.
