This is insanity. TS0P is sensor inside trackpad cable; the cable going between the trackpad and the motherboard. Why are you people replacing the entire case over one stupid cable?
Further, TS0P shares I2C_ALS_SDA & I2C_ALS_SCL data line with other sensors, so it is possible that the webcam is pulling the TS0P sensor line down. Unplug webcam/wifi/bluetooth cable and see if you still have same failure.
