here's my email ... jjohns04@pnc.edu. I'm an electrical computer engineer amongst other things. I have to do the same repair as soon as my friend gets back from Iraq next week. If you have the triwing screwdriver and have the back off... F1 and F2 are marked by the letter F on the circuit board.
Link is a pic of a DS board... if the board is the same as yours... cheers. If you need help ... please email me.
