Have you tired posting on digital-car the UK site? You might have some luck on there.
You could also try giving linITX a bell as they sell parts for their monitors which also use the hitachi panels so they might work.
As for the TS, i is just an overlay made from a couple of mm of glass and some plastic which links to a small USB controller so no it wont matter if you get a panel from a TS version.
While i am here, if your screen is fubar any chance of sending it over for me to take apart (read sig and this thread for reasons: LCD Backlight Upgrade )
