How to replace the Digitizer
I have a cracked digitizer, and have purchased a replacement. Note: This is JUST the digitizer, as my LCD screen is fine. I get the phone broken down as far as I can get, with the screen component completely apart, but can't seem to figure out how to get the digitizer off of the LCD screen. Do I need a heat gun or something?
Usually when the digitizer and LCD need to be separated, you'll need a heat gun, thin prying tools, and a lot of patience. My two prying tools of choice are our guitar picks or a plastic opening tool.
Soft tip prying tools for DIY electronics repair. Use to open your iPod, iPhone, or any other sensitive mobile electronic devices. The soft plastic won't scratch your device, but the strong tip will easily pry it open. It's the essential tool for opening — 50+ available at 2.95 each.
Thin prying tool for opening electronic devices. Guitar picks are essential to open any iPad, tablet, or smartphone sealed with adhesive. — 50+ available at 4.95 each.
Your correct. I probably should not have posted after screwing up a nice 4G LTE screen at the very end of an hour plus of fiddling. Anyway as you say doing it by hand is (just barely) possible but its too time intensive for me *I'm running a microbiz.
I dug around some more and found a you tube video titled "How to separate the screen from glass using SM-252 separator" In short its an adjustable hotplate so you can insure you don't cook the lcd. Then you use a Molybdenum Wire (Like a garrot) to slice the glass (Or Digitizer) off in one clean cut. To get all the glop (glue) off the Display you can use a chemical called LOCA or LPA and an ordinary toothbrush. They have a glue to rebond the LCD to the Glass (or Digitizer) *Note you need a Ultra Violet light sounce to cure the glue. They sell UV flashlights on Ebay and probably a number of other places.
