I dropped my FP3, now it's dead

My FP3 was working well but yesterday I dropped it and now it’s not charging or turning on. The battery was OK before the fall and would have had 50/60%, I cant check the voltage because the probes on my meter are too thick but I am going to get that checked tomorrow and the fact remains that when plugged in I get no buzz or LED.
Some forums have suggested that the fall may have dislodged a connector and to dismantle and rebuild it. I have removed the display unit and popped the connectors between the various modules and the motherboard then re-assembled it all but it has made no difference. Is there another level of disassembly that I should try? Is there something that anyone can suggest that might bring it back to life?
