Definitive method for glass only repair
This question goes for pretty much any iphone, not just the 5.
Has anyone managed to develop a method which leads to having a decent screen after replacing just the glass?
I feel I am close, but am ultimately missing a couple of vital things.
I can successfully remove the broken / cracked glass and all the old adhesive and still be left with a good lcd and digitiser.
What I do next is desolder the backlight from the lcd and replace this with an older already damaged backlight - this is just to make up the correct thickness in order to place the assembly into a jig. I remove the original backlight in order to prevent any of the loca glue from getting in there.
I then use the loca glue and attach a new piece of glass to the lcd. Take it out and clean it up, removing all excess loca glue. I use ipa to clean the back of the lcd panel (although I can never get this looking 100% as it did originally)
Once I'm sure all the loca is removed, I resolder the backlight and secure it back in place. I connect the display back to the phone and hey presto, all is good.
I then fully assemble the phone again, but by the next day, some of the loca has leaked out into the backlight! - and the backlight will sometimes flicker.
No major drama, I can just switch the backlight for a new one again, ensuring that all further traces of loca are cleaned up.... But by now, even if the display looks fine, the backlight still has a flicker. This can't be down to the backlight filter on the phones motherboard as a new display assembly connected to the same phone works perfectly.... So, even though I'm being very careful soldering the backlight back on, am I causing some kind of damage in doing this?
Can anyone see where I'm going wrong? Who routinely does this with good results?
Thank you for reading.
Ist dies eine gute Frage?
