tvmitc could be either a bad digitizer (most likely) which would need to be replaced once more or a loose connection. Double check your work and make sure that everything is properly connected. If so, contact the vendor your bought the touchscreen from and ask for a different one. Badd parts and poor QA are not an uncommon issues.
