I'm facing a similar problem, i cant even make the touch work.
I'm new here, and i got a problem that probably will be in futher also a problem for someone maybe.
I just bought a TFT http://www.ebay.com/itm/111114349519
400x240 as recommended and seems the LCD its working fine, just the calibrate its a lil hard to do.
I dont know what more can be done, but i believe its impossible to calibrate it, since i cannot sucess to do it.
Someone faced it before or know another way to calibrate?
I'm also tryng with lastest URtouch and UTFT to find a way to calibrate, no sucess...http://www.rinkydinkelectronics.com/
All help will be welcome, and futher customers also will need help probably.
