Thx, I did it with a TZ8 and it works with the same mechanical design.
My big dust in blue sky is no more there and I'll enjoy my camera for a couple of month more ;-)
Only one comment about PCB connector, I disconnected it to make it easier but not so easy to replug during reassembling! But it's done. So if you can avoid it, my recomendation is to not disconnect any cable.
