Hi all Our 15" Ti suffered a tragedy. Its left screen hinge was broken and the display is completely black. It still functions in target-disk mode. Don't know about display mirroring because cannot read the display. We have PowerBook models back to the 5300C and this the first time a display has failed so we have no experience with this kind of failure. The questions are, is it difficult to repair and is it worth its repair cost or should it just be replaced? TIA, CDG
