Why my Sony A6400 not turning on

When my A6400 change to a new mainboard, I install everything but the problem is that it doesn't power on. Did I miss something?Where was the power of the sony a6400?

Hello there, my guess is that the top flex cable is compromissed, more specifically the mini shutter lever that is on the top flex cable. My a6400 is presenting the oposite of yours, it’s always turned on, when I put the batterry is working no matter which way I turn the “on/off” button.

Maybe you should try to replace the top flex or the entire on/off block, find below links of these components;
