myriad things could have gone wrong, you should check if the cable its properly connected, also the cable might be faulty or even the LCD

LCD is fine, can it be a problem if i don't conect this flex cable all parts well, for example i didn't connect well with loudspeaker?

But before i changed the old one flex cable which has broken microphone connection, which goes also from flex cable, the LCD display works well, but after i changed it to new flex connection, the screen didn't work, when i replace it again to old flex cable and screen also didn't work.

You have few options, contact your Local support maybe they can test it for you, if not then you will have to buy a new LCD and test it yourself.

I have got 2 new LCD screens and they doesn't show anything, there is a problem between  motherboard and lcd screen connection, because everythink work fine except LCD display.

Anyone know how to charge the battery without phone. I take out a battery and want to charge it somehow. Any ideas?

check online for third party battery chargers, you are aware that this will void the warranty if you haven't done it just yet.

I changed LCD display by myself, so warranty is over.And i can't find that charger for xperia Z2, because this battery is with flex cable which connect with motherboard. Maybe is another way to charge  battery?
