*FIX* no touch after screen replacement - GSM-Forum

echow2001 · 08-13-2018, 22:47

screen repair went as normal but had to reconnect old bad screen to reset so it would open up to pair with new screen. that went normally but after connect new screen touch not work. my solution is to look at it under microscope and see if there are any cracked contacts on the ZIF and if so, put flux on connector and put tiny amount of solder to re bridge it to fix. hope this help

Use a chisel-type blade (like Xacto #17) to remove the module. Then you can reattach it with Z-tape. If Z-tape is not available (you can get it from e.g. Adafruit) use conductive ink on the two bumps and then superglue for strength. The second method is more fiddly.

The two solder points underneath the module are NFC antenna connections.
