I installed new rom ( NBD 8.3 ) After that touch screen is not working

I had a similar issue with another rom the other day, it turned out to be totally unrelated to the flashing of the new rom. I found i had a small piece of lint stuck between the screen and the screen surround, cleaned it out and the touchscreen worked perfectly again. Check really good around the edges of the screen to make sure there isn't any debris pressing on the screen. Then if it still doesn't work, try to flash back to original rom and reflash the new one and see if that resolves the issue.
