Hi Adrian. Did you do a proper decontamination of the logic board (ultrasound etc.)? Was the water damage extensive or localized (if so, where)? Which Touch IC did you change; Cumulus, Sage or both? The more information you give us, the better the answer will be.
You should probe the the Touch IC voltage rails, both input and output and get to me with your findings.
