Thank you thank you.... I made few mistakes.... one of the cable got detached and I have to tear my camera apart to be able to fix the cable that was going underneath the bottom....
Everything is working well now ! Thank you very much
Next time I will do it differently. I will draw on a piece of paper what I see and put a needle hole on each screw on the paper to place the screw inside it.
The screws come on different size so it is important to know where goes each. I had more screw to unscrew that what it was initially planned.
