    Very detailed set of instructions! Does anyone known the thread size of the screws in step 2? 8.4 mm T5 screws: is the length of the screw (8.4 mm) ,and the head specification (T5- size of screw driver). I need the actual thread specification. I lost one of the screws and the other one 's head is stripped. I need to replace both screws.

    • Remove touch screen by using the plastic opening tool as a wedge to pry the touch screen from the case.

    • It is easiest to do this by pulling on the side tab as you wedge the touch screen away from the case.

  6. RBOuGLXjYUwalgpu

    • Lift the touch screen above the mother board so that its position is similar to what is shown.

    • Remove the tape connecting the gold ribbon cable circuit to the motherboard.

    • Peel the tape off slowly so there won't be any damage to the motherboard or gold ribbon cable.

    • Lift up the tab connecting the gold ribbon circuit to the motherboard, using a plastic opening tool if necessary.

    • Gently remove the gold ribbon cable.

    • To insert a new screen in, attach the gold ribbon circuit to the motherboard by sliding it in place and pressing down on the tab. This may take a few attempts before it is connected successfully.

    The gold ribbon cable must be fully inserted under the flap. If there is no resitance in closing the flap, then it is not inserted all the way. It is difficult and takes patience with a steady hand. The tiny pins on the underside beneath the flap must penetrate the ribbon cable. A good magnifying glass is helpful.

When do i find replacement glass

I just purchased an aftermarket touch screen with digitizer on ebay for $17 USD from a Chinese seller. Will update here with item listing # if the item is successfully installed and works.

I just got my aftermarket screen today. One thing worth noting is that these aftermarket screens don't have that thin adhesive shock absorbing stuff around the perimeter of the screen and it's impossible to take it off the original screen and reuse it. I used pieces of weather stripping that I cut down thinner. This isn't necessary for it to work, but it helps provide some protection.

I installed it about 3 hours ago and everything seems to work fine. How long it's going to last is another story.

If interested, you can buy the screen from ebay seller mingxing200808 Item # 400709570325. I live in NE USA and amazingly I got my screen in a little over a week after I completed the purchase. Not bad.

BTW: for those that just need the digitizer, you can pick one up on ebay for just a coupe dollars, however I have no idea how hard it would be to remove the old one and replace the new one. Looks like it might be harder than just changing the whole screen+digitizer kit.
