the touchscreen (digitizer) is separate. however, its very delicate.. even if it doesnt appear broken, if the LCD has taken enough pressure to break, it's likely the digitizer has been harmed as well.
I got one here
eBay: LQ035Q7DH04@Toshiba e400/e410/Dell Axim X3/X30 LCD Scrn (item 290092226521 end time Jul-06-07 20:28:46 PDT)
thats $85 and he'll have it to you in about 6 days. amazing really.
The LCD was perfect, but the digitizer he sent me wasnt very responsive on the side and bottom. He offered to replace it, even tho it was weeks after the sale when I noticed the issue. So... 1/2 the cost of a local replacement, but alittle more inconvienent to get service.
the PPCtechs service is great.. but that is the cost of whole 'nother unit. :( It makes the ebay/chinese/self replacement a much better value. For a x51v, that would be a different story, they are still worth 2x more than the cost to repair.
anyway, I've done a few replacements.. and you can easily separate the digitizer and it's metal frame. dont try to take the glass of the frame, you'll break it. the metal frames separate. super easy.
if you junk the unit, please PM me.
