Touch screen on hand controller stop responding to key touches froze up on polar align screen after switching off back on again started changing display languages, at random press key would jump from one to next but not change screen then would freeze up again. Reformatted SD card and reinstalled HC firmware made no difference. Will boot up and go through first screen calibration OK but second calibration would not work. Any clues or know anyone in OZ that may be able to repair one can the touch screen be swapped out for another sort ??? HELP
