Thanks for the replies.

Stoobie is correct.. having read through the TSU3000 thread that Lyndel linked me to, it seems to be a different problem altogether;

In my case, the touch function of the screen is retained, but the screen only displays a white image (so can still be used if I guess where on the screen I need to press)

I've ordered a replacement screen, but having searched around and read a bit, I fear it may be a board or comonent issue.

If this is the case, does anyone have any information regarding the board i.e. links to schematics, or which chips on the board control which function?

Any help at this stage would be great
Thanks,
Stu
