I have 4 LCD 4.3" with an BB-view. I calibrate two them without problems deleting /etc/pointcal and running ts_calibrate. But I cannot calibrate the other 2 LCDs, when I run ts_calibrate it finishes quickly (in less than a second) as someone would had done the calibration, ts_calibration finishes without errors. I thought one of the LCDs could be damaged but the other one is new.
Do you know which could be the problem?
Thanks
