Hi there,
Sorry to bring some bad news here but just as a word of caution : if you're going to replace the screen on your iLiad you may want to read following link. As it happens it requires a whole lot more skill than just the replacement of the screen itself and may in fact be completely impossible for lamen unless you get one that happens to be exactly from the same screen BATCH (with the same Waveform settings...) , but that is nearly impossible without information from iRex and 'tuning' a screen from a different Batch seems to be difficult, if not impossible.
