I recorded a video showing the problem I hope you can help me , thanks.
Youu can't calibrate a broken touchscreen, which your is as it appears that any place you touch registers it at the lower right hand corner (4:37-5:16)
The reason the calibration fails is because to it, you are just touching the same place no matter the location of the cross it indicated (It senses every touch as that lower right section.
So buy a touchscreen and replace it is your only avenue. If you have a maintenance agreement, use that, if not, there are many out there at low cost.($10-$100 in the US)
