No service after screen replacement?

Try a different sim on the same network, double check antennas are connected properly (clean with alcohol and reconnect)

Got the same issue on my private G2...replaced cracked screen - screen works fine but now I've got (almost) no service. Did anyone find a solution in the meantime? Double-checked all connectors and antenna cables several times, but still no improvement. Any helpful advice would be highly appreciated!

"I am in the same boat. My LG G2 screen was cracked and I replaced it successfully. Only thing is that there is no Network. Cannot make calls as no network Signals.

Wi-Fi is great, speakers, screen, camera etc all are working fine. I checked antenna cables, connections to the motherboard. Everything is fine. I even ruined my back cover connectors by watching few videos where people inserted some paper behind the copper connections (On the back cover).

I do not understand what is the problem. Only thing that is left is to change the whole antenna module but I am not sure that is the problem as it is a sturdy piece held by 5 screws at the bottom. I am stumped... Tried googling the answer but there is no explanation or solution. Please if you find a solution post it every where as people are stumped with this problem...Many thanks.

Update

By the way I checked the phone with different sim cards and the problem appears to be with the phone. I am really disappointed as I have voided the warranty now and probably will have to pay for an expensive repair or something"

Did you find a solution for this?

Ran into this problem as well. My tech changed out an lcd assembly for a LG G2 over the weekend, and the customer came back yesterday unable to make phone calls but able to use everything else. When I opened the phone I found that it was missing the white wire that runs along the right side of the board. I replaced it and solved the issue. Make sure the pair of cables are properly connected; hope that helps
