Anyone know how this issue might be rectified? It turns on but won't respond to screen taps. Have tried cleaning the screen and stylus and have tried a soft reset (and yes i have checked whether it is locked).

This happened to anyone before?

Do the hard buttons work; if yes I suspect the digitiser has gone, proaly  est just to get another unit. If no the battery lock switch sometimes goes, soldering can sort this out, but cannot remember which pins. I do have it somewhere, will try to rememer to look it up.
