For me this is another problem repairing newer electronics. Manfactures who use surface mount devices not because there is not enough room, but because they are cheaper to build by robotic placement, wave soldering, etc. and no thought is given to repairability. Even if you can find the replacement smd. and using a high end Pace solder system it can take you an hour and a half or longer to remove and replace one of those chips. Ok, I feel better now, end of my rant.
