I had this problem last week and Nick Swayne gave me some excellent advice.
LEGO will replace your faulty NXT at no cost because the display issue is a
known problem. You may have a problem b/c you attempted to repair the unit
but you can always ask. Below is the number I telephoned. The
representative told me to write a brief note explaining that the display was
intermittent and include my return shipping address. He gave me the address
below to ship my NXT. I asked if any kind of RMA (return merchandize
authorization) number was required and he said no--just include the note
about the display and the problems I've encountered.
