Hello,

Looks like your pin10 has only 2v it should be 3.3v. Try to measure r4830 pin 1 and pin2

When I unfasten the tape.

Ok, try disconnecting keyboard from trackpad, and leave only trackpad connected. Are you sure you connected ribbon cable in good orientation? Golden pins has to be downwards on board and trackpad.
