Sony Z2 D6503 touch/digitizer problem!


Hi

I have problem with Xperia Z2 D6503, touch screen not working.

In 3 new set (2 replacement and 1 orginal), touch not working.
On the NEW mainboard in phone, 3 set working fine.

Capacitors and resistors near lcd connection look good.

It started with the fact that exchanged power flex and i changed 4 flex (used, orginal from disassembly) and in each of the flex is not working some button.
I bought replacement flex and connected to mainboard and then touch screen not working.

Please give me solution!
