Hello everyone - I replaced a non functioning PRONTO NG TSU 3500 screen (not the LCD the glass part on top) with a kit I bought from eBay for 29.99. It included the replacement screen glass and all the stuff you need to do the work yourself (except a cheap soldering tool) including a really good manual with a lot of pix. I emailed the seller with a question before I started the repair and he sent me back his cellphone number and his FaceTime info - he walked me through it by video-conf the next day. Way better value than going to that one repair place that is owned by Philips. As of now the listing is still active.
