[Your turn SF]. Ehhhh Stewie ..... He took it apart and reseated the cables [first post].
Some digitizers are soldered into the LCD's ribbon and there is a common flat connector, they are an absolute bit*h to repair. Others have a separate connection to the mainboard and are relatively easy to replace. I recall that 6x0, 7x0 and some 2xx share the same screen configuration and the digitizer is separate and easily replaced. They are very cheap, from US$2 to $3 upward posted from China or Honkers. Just be sure to use a hotair gun or hairdryer to loosen the sticky brown tape before removing the old one from the LCD screen. Have a look on ebay.
