Some other things to check......

When the phone powers on fully..the display will be illuminated and then the backlight will go off.
After the LCD backlight goes off...press for a short time the power on button and check to see that the backlight comes back on again..post results.

In checking the skems for V3RE... there are only 2 componants between the keypad flex and the controller...a filter and a protection array...see below.

You can remove VRBB1 and then check to see if keypad operation is back to normal

If you remove FL1401, be prepared to replace it, because keypad signals pass thru this filter and its in series with the controller.
