I had a nasty incident with a pickle jar and my Pronto about 2 weeks ago which cracked the screen. Man, was I pissed off! You don't realise just how useful the Pronto is until you have to go back to using 7 different remotes.
However I ordered a Samsung UG-24U01-WGHT3-A screen from www.earthlcd.com
, followed the instructions in the FAQ very carefully and now have a fully working Pronto again. Hooray! I had to trim the plastic support bezel slightly to accomidate some capacitors which aren't on the original screen, but apart from that it all went smoothly. The backlight slightly nosier than the original screen and the touch sensativity is less, but it works beautifully.
Many thanks to FAQ authors and to the people who posted their experiences in the forums, without the info here I'd never have fixed it!
