Sony PRS600 screen lookup table

Hi all.
The problem with this otherwise working e-reader is that the screen calibration waveform is incorrect resulting in multiple ghost images of previous data.

The panel is one with the black dot and -1.29V set voltage but adjusting the trimpot made no difference so its the waveform which is evidently wrong.

There is a procedure to update it but Sony won't give me the information ie the waveform for the particular screen.

Any ideas?
