No screen, before white screen and disturbance

Dear

I opened my tablet because:

Samsung Galaxy Tab 2 (P5100) 10.1

I have no screen anymore, I see sometimes white screen if I press on the power button, sometimes it related with disturbate.

If I touch the LCD ribbon then I see white screen with disturbations.
So I ordered an original LCD ribbon.
Same result.

I also tried to connect it on a laptop. He can find the tablet, also in samsung kies.
But no screen.

I also tried to reset it by VOL+ + VOL- + Power button.
I can feel it restarts but that's all.

I also pulled out the battery for an half hour and all the ribbons but no result.

Can someone help me please?

Thank you!!
