I used laptopscreen.com.
Use a purpose built heating pad at 100 degree Celsius eg; https://www.aliexpress.com/item/Uyue-948...
I used a purpose built heating device at 100 degree celsius. Lower temperatures didn't work.
I would suggest getting the cable loose first as the vibrator comes out suddenly and you could break off the cable if it is still glued down.
And the answer is in here. It sits at 8.9 then ramps up when it is happy with everything. http://www.righto.com/2013/06/teardown-a...
Why is it 6.8 V and not 16V?
Why wouldn't we check the voltage here instead of later?
It took 1.5 hours to do the second one.
I've done many phones and ipads in the past. I did 2 of these in a row. Both screens were broken before hand but I was unable to remove either of them completely without leaving fragments around the frame. This would suggest that replacing the drive on one with a good screen will require a replacement of the screen too. Do not put a tool into the speaker areas as it mushes up the screen and requires you to glue the screens back in. The screens I purchased did not have adhesive with them so you need to apply that before plugging the screen back in. I ran 1 or 2 stips of 2 mm tape depending on the with of the contact area. There was a metal cover over the right hand connector on mine. I found the metal covers easier to remove with a dental pick which I inserted into the small holes on each tab then levered up. You have to transfer a small board over to the new screen which requires heating. Make sure to connect the LCD to that board before sticking it back down. Ken Davison meditlondon.com
While reassembling it's easier to insert the cable into the connector while placing the SIM board into place. This allows you to get the end of the cable back enough and slip it into the connector.
