I need help with a scheme. For repair Please.

From now very grateful.

Hi, your thread is old, but this can be helpful for others with same problem.

1. Unscrew 2 screws at top of your phone, under the sim tray and under usb port cover.

2. take out lcd and disconnect TWO Ribbon cables from Main board.

3. Connect the Wider flex connector to Mainboard and leave your second connector unplugged. or alternately you can take that smaller flex out from lcd assembly like this: http://i.ebayimg.com/t/Nokia-Lumia-8...29g~~60_35.JPG

4. Reassemble your phone

5. Done, check your touchscreen.

i dont know why, but disconnecting Proximity/Light sensors Flex helped for me.

you know what will u lose by this. but its small sacrifice, at least youl get your TS working.

press thanks if its helped for you.
