Well All,
I was able to get the Ipronto apart successfully without breaking anything.. seems there are some plastic teeth that need alittle "convincing" to open... once i got it all apart.. i thought i would be able to reconfirm the cable connect to the TS Screen. no luck.. I was able to check the entire unit... physically to confirm no visiable issue. none found.. after getting it all back together... still the same issue though .. calibration failure.. tried different icf. files, tried reloading the latest firmware.. tried the default icf. the only thing left i can think of is to try an older firmware option?? anyone know where i can get one???
