Smashed the screen. Everything worked, but the cracks are prevented. I bought a new display module. Disassembled, laid a charge — not working. Thought defective. Bought another one — no picture. Sound, vibration, everything is there. The charging indicator (red light in the corner of the display) is on. Backlight and no picture. Under the microscope looked all paths intact. Circuit Board no. What may be the problem? Is also the second marriage?
