Answer to "Why isn't the LCD displaying anything after replacement?"Inspect the display cable (the one with 51 pins on it!) and it's connectors really well, if a connector's had a knock you may be able to see/feel if it's loose. inspect for dirt/grit/lint/glass inside them too. If the connection is happy you should be good to go, I had no such problem with mine. unplug the battery again, for an extended period of time, and after that leave the charger plugged in for a few hours (unless you can hear the machine is on) and try again.
