The original screen has the following code stamped on the back of the display: "TL055VDXP34-00".

The first replacement display assembly (did not work) had the following code: "TLD55VVXP31-00".

The second replacement assembly (did work) had the following code: "TL055VDXP34-00".

On that basis, I would suggest that the first unit I received was an earlier model, and was the incorrect part. I assume that the replacement display assembly must be model TL055VDXP34-00.
