Has anyone got any tips for heat shield installation?

After successful lcd refurbish we go to install the lcd on the original device. This is ok up until the heat shield installation and subsequent full installation of the screen. It seems to work fine when it is out of the phone but once set in place there seems to be a “dead” spot right down the middle.

we can only suggest that the ribbon cable gets pressure from a push, or twisted from installing - has anyone got any tips how to install the metal heat shield as we thin this is causing the issue? The touch will not work until the device has been locked and unlocked again.

thank you

U need to make sure the big grey chip is in the correct spot. Push the flex cables with the phone slightly open with the bottom of ur tweezers so the flex folds inwards… if the patch is down the middle vertically then it might be a swollen battery as it's an LCD refurbish it might also be the oca ur using or the glass being too thick etc, lots of different factors

Make sure the rim of the housing is clean no lumpy left over adhesive and when u push the screen in push it upwards firmly first and then equally down on both sides working downwards, important part pushing it hard as u can into the top corners…

do you bend the flex`s out straight when refurbishing? this used to cause me issues as they are so fragile, best to keep them formed with the bend whilst refurbing.

Yes we need to because our polariser remover and applicator machines means the cables need to be at 180 degrees flat. I have just had success by applying a small bit of tape to secure the flex cables in place with the correct amount of tension, hopefully this is a successful workaround going forward. Apple obviously use the adhesive on the heat shield but I am reluctant to try that as if I need to remove for another reason it will become painful!

It could be the polorizer layer as well we've had some issues with some oca some polorizers and even some glass just being just that little tiny bit iffy thicker/thinner and it causes problems
